Highlights Our main leading indicator for China’s economy and the broad trend in coincident measures both suggest that investment-relevant Chinese growth is set to slow over the coming months. Even in a trade deal scenario, an earnings recession for Chinese investable stocks looks likely unless the flow of credit soon increases to an annual pace of RMB 26 Trillion. The recent trend in money & credit growth is not yet consistent with this outcome. The RMB has risen relative to several currencies over the past two months, meaning that it does not simply reflect a weaker dollar. The RMB rally is linked to the trade negotiations with the U.S., suggesting that further gains are likely if a genuine truce emerges. Feature Tables 1 and 2 on pages 2 and 3 highlight key developments in China’s economy and its financial markets over the past month. On the growth front, our Li Keqiang (LKI) leading indicator continues to point to weaker activity over the coming 6-12 months, even though the LKI itself has actually trended higher over the past year. We maintain that trade frontrunning has caused this gap (which is in the process of unwinding), as broader measures of coincident activity have been trending lower and are poised to decelerate further. The growth rate of housing construction also seems set to decline, given that the current pace of starts is still running substantially above the pace of sales volume. Finally, while we do not expect the speed at which Chinese import and export growth decelerated in December to continue, the export components of China’s PMIs and the end of trade frontrunning both suggest that trade growth will remain weak over the coming few months. Table 1China Macro Data Summary China Macro And Market Review China Macro And Market Review   Table 2China Financial Market Performance Summary China Macro And Market Review China Macro And Market Review From an investment strategy perspective, we continue to recommend a neutral stance towards Chinese stocks within a global equity portfolio over a 6-12 month horizon, and remain tactically long until the end of this month. The recent outperformance of investable stocks vs. the global benchmark reflects global investor expectations of a trade deal between China and the U.S. later this month, but a deal alone will not reverse slowing domestic demand (which will negatively impact earnings). Even in a trade deal scenario, an earnings recession looks likely unless the flow of credit soon increases to an annual pace of RMB 26 Trillion, and the recent trend in money & credit growth is not yet consistent with this outcome. Finally, the rally in the RMB over the past two months does not simply reflect a weaker dollar, as it has risen relative to several currencies. The timing of the rally is clearly linked to the trade negotiations between the U.S. and China, suggesting that further gains are likely if a genuine truce emerges later this month. In reference to Tables 1 and 2, we provide several detailed observations concerning developments in China’s macro and financial market data below: Both the Bloomberg Li Keqiang index (LKI) and our alternative LKI rose to 9.3 in December, maintaining an uptrend that has been in place for the majority of the past 12 months. As we noted in last week’s report,1 this uptrend is not only in contrast to our leading indicator for China’s old economy, but also other coincident measures of economic activity. Chart 1 highlights that China’s investment-relevant economic activity is trending lower when broadly measured, implying that the uptrend in the LKI over the past 12 months is anomalous and is set to wane. Chart 1China's Investment-Relevant Economic Activity Is Trending Lower China's Investment-Relevant Economic Activity Is Trending Lower China's Investment-Relevant Economic Activity Is Trending Lower Our LKI leading indicator ticked down in December, as a rise in the RMB reversed some of the improvement in monetary conditions that had previously lifted the indicator. More important, however, is the very recent trend in the money & credit components of the indicator: while the YoY growth rates in M2, BCA’s calculation of M3, and adjusted total social financing (TSF) have recently stabilized, Chart 2 shows that the trend over the past three months has been down. We highlighted in last week’s report that Chinese credit growth needs to accelerate this year to avoid an earnings recession even assuming a trade deal with the U.S., and Chart 2 illustrates that the recent trend in money & credit growth is not yet consistent with this outcome. Chart 2The Recent Trend In Money & Credit Growth Is Down The Recent Trend In Money & Credit Growth Is Down The Recent Trend In Money & Credit Growth Is Down Based only on the trend in construction, China’s housing market is healthy and growing at a robust pace. However, fundamental support for the housing market is materially weaker: housing sales volume growth is in negative territory, growth in PBOC pledged supplementary lending injections has turned negative, and our house price diffusion indexes are rolling over from elevated levels. Housing sales volume has historically led the trend in construction, suggesting that China’s housing inventories are rising anew and that the pace of construction is set to cool significantly. The NBS and Caixin manufacturing PMIs for January provided conflicting readings: the former ticked up fractionally, whereas the latter deteriorated meaningfully further. The fact that the new export orders components of both PMIs moved higher in January suggests two things: 1) exporter sentiment is stabilizing (at a low level) in response to expectations of a trade truce with the U.S., and 2) the domestic demand outlook is weaker than the external outlook. This underscores that a framework trade deal with the U.S. at the end of the month is not, on its own, likely to lead to a significant reacceleration in the Chinese economy. Chinese investable stocks have rallied significantly in absolute US$ terms since the beginning of 2019, up over 11% year-to-date. Given that Chinese stocks are comparatively high-beta, most of this performance can be attributed to the rally in global stocks (up 8% YTD). However, it is notable that Chinese stocks outperformed global stocks both when the latter sold off aggressively in December, and in response to the recent global rally. This likely reflects global investor expectations of a trade deal between China and the U.S., which was the basis for our recommendation of a tactical overweight towards Chinese stocks in our December 5 Weekly Report.2 Chart 3 provides some additional evidence that global investors have driven the recent rally in investable stocks. First, panel 1 highlights that domestic stocks have underperformed investable stocks meaningfully over the past two months. Second, panel 2 shows that domestic infrastructure stocks, likely beneficiaries of a policy-driven reaccleration in domestic demand, have not rallied at all in absolute terms over the past few months. Chart 3Global Investors Drove The Recent Rally In Investable Stocks Global Investors Drove The Recent Rally In Investable Stocks Global Investors Drove The Recent Rally In Investable Stocks Within the equity sector space, the most notable development over the past month has been the substantial outperformance of Chinese consumer discretionary stocks (up almost 11% relative to global consumer discretionary in US$ terms year-to-date). For the most part, these gains reflect the idiosyncratic performance of Alibaba, due to recent changes to the global industrial classification standard (GICS).3 Prior to the changes, the automobiles & components industry group competed with retailing as a driver of the Chinese investable consumer discretionary sector; today, retailing accounts for 3/4ths of the index, with Alibaba accounting for all of the increase in retailer market cap (from 26% in November). Alibaba’s stock price recently bounced in response to a positive Q4 earnings surprise, but disappointing revenue growth underscores the challenges facing investable consumer discretionary stocks from deteriorating consumer sentiment in China.4 Despite the rally in China-related global financial assets over the past two months, Chinese onshore corporate bond spreads remain elevated in reflection of concerns over rising defaults (Chart 4). While we believe that investors are pricing in excessively high default rates over the coming year (i.e. the level of spreads is probably wider than warranted), the trend in onshore corporate spreads is highly informative and served as an early indicator that China’s economy was set to slow. Somewhat concerningly, the trend in spreads of different quality are not moving in a direction that would be consistent even with a stabilization in the Chinese economy. Panel 2 shows that AAA-rated corporate bond spreads have recently been trending higher, in contrast to that of bonds rated AA-. The former has reliably led the latter over the past year, implying that the odds of overall onshore spreads rising have gone up. Chart 4High-Quality Corporate Spreads Are Moving Higher High-Quality Corporate Spreads Are Moving Higher High-Quality Corporate Spreads Are Moving Higher The budding rally in the RMB that we identified last month has continued, with CNY-USD having recently broken above its 200-day moving average (Chart 5). Panels 2 and 3 highlight that this does not simply reflect a weaker dollar, as the RMB has risen relative to the euro and the basket of currencies included in the Bloomberg U.S. dollar spot index. It remains unclear whether this recent strength has been driven by trade talk-related intervention or market expectations of a trade deal, but its link to the negotiations is clear. This suggest that further gains are likely if a genuine truce emerges later this month.

Highlights So What? The late-cycle rally faces non-trivial political hurdles. Why? The rally is based on a too-sanguine view of the Fed, China, and the trade war. Other issues – like Brexit and the U.S. border showdown – are also problematic. Venezuela still has the potential to push oil prices sharply upwards. Feature All is well. Global equities are on the path of recovery, as should be the case at the end of an economic cycle. The U.S. S&P 500 has gained 16% since the bottom on December 24, with healthy technicals suggesting a breakout is ahead (Chart 1). The S&P 500 may be entering one of its typical late-cycle rallies, which tend to be the second best-performing decile of a bull market (Chart 2).1 Meanwhile, emerging market equities and currencies are outperforming developed market peers (Chart 3), a reversal from 2018 Chart 1Late Cycle Rally Ahead? Late Cycle Rally Ahead? Late Cycle Rally Ahead?   Chart 2 Chart 3...As Does Current Global Outperformance ...As Does Current Global Outperformance ...As Does Current Global Outperformance Typically, global risk assets outperform American risk assets at the end of an economic cycle. While institutional investors can use these rallies to lighten the load ahead of a recession, most investors cannot afford to miss such a rally. As such, BCA (and others) are calling for investors to play what is expected to be a yearlong rally in global risk assets and the S&P 500. Our view at BCA Geopolitical Strategy is more cautious, perhaps because it is informed by a methodological bias rooted in geopolitics. We believe that the reversal in U.S. outperformance relative to global risk assets rests on three pillars: The Federal Reserve remains dovish throughout 2019; China begins a major reflationary effort;  The U.S.-China tariff truce results in a trade deal. In addition, a consensus is emerging that a “no deal” Brexit will not occur, that U.S. polarization cannot get worse, and that President Trump eschews foreign interventionism. While we hold a nuanced view on each of these assertions, the mix is far less bullish than investors may think. We see a witches’ brew of factors that is murky at best and bearish at worst. The Three Pillars Of The Bullish View Before we turn to geopolitics, let us examine the three pillars underpinning the bullish view. Our colleague Peter Berezin, BCA’s Chief Global Strategist, remains bullish on the U.S. economy and expects the Fed to resume hiking rates by mid-year.2 The Conference Board’s Leading Credit Index remains in expansionary territory (Chart 4). While business capex intention surveys have come off their highs, they still point to robust spending plans over the next few quarters (Chart 5). Chart 4Little Sign Of A Looming Credit Crunch Little Sign Of A Looming Credit Crunch Little Sign Of A Looming Credit Crunch Chart 5Capex Plans Still Solid Capex Plans Still Solid Capex Plans Still Solid It is no surprise that the BCA Fed Monitor continues to suggest that “tighter monetary policy is required” (Chart 6). This is a far cry from 2016, when our indicator was in deeply “tightening” territory and the Fed paused for 12 months. If we compare 2019 to 2016, it is difficult to see how the market expectation of 4.72 bps of rate cuts will occur over the next 12 months (Chart 7). Of the three components that make up the BCA Fed Monitor, only the financial conditions have fallen into “easing required” territory (Chart 8), and they are already shifting back to “tightening required” territory with the stock market rally underway (Chart 9). Chart 6A Hawkish Fed Is Needed A Hawkish Fed Is Needed A Hawkish Fed Is Needed Chart 7 Chart 8BCA Fed Monitor Calls For Tighter Policy BCA Fed Monitor Calls For Tighter Policy BCA Fed Monitor Calls For Tighter Policy Chart 9Financial Conditions Starting To Ease Financial Conditions Starting To Ease Financial Conditions Starting To Ease In addition, in 2016 the Fed was not contracting its balance sheet. Today it is doing so, although the pace has moderated. As such, the Fed’s rate hike pause is occurring amidst an ongoing effort to normalize monetary policy and to transfer rate risks back to the private sector. By chance, this is also occurring at a time when the Treasury Department must issue more debt to cover a larger deficit, a process that could significantly pull U.S. rates higher and, by extension, yields on assets further down the risk curve. This would be a particular problem for global risk assets given the exposure of several EM economies to dollar-denominated debt.  The bottom line for investors is that a rate hike pause is not a pause in the overall hawkish policy of the U.S. Fed, which acts as a global central bank. The fall in the amount of dollars available for the international financial system acts as a brake on growth. Over the past 10 years, each time money supply growth fell below the loan uptake of the U.S. corporate sector, BCA’s Global Industrial Activity Nowcast, BCA’s Global Leading Economic Indicator, Korean exports, and global export prices all deteriorated considerably (Chart 10). Chart 10Deteriorating Excess Liquidity Hurts Global Growth Deteriorating Excess Liquidity Hurts Global Growth Deteriorating Excess Liquidity Hurts Global Growth Our muted view on Chinese reflation is unnecessary to repeat here. There is no doubt that Chinese policymakers are stimulating the economy, but the question is whether they are willing to pull the credit lever as aggressively as they have done in the past (Chart 11).So far, all of the evidence we have reviewed point to a cautious effort to stabilize growth, not reflate the entire planetary economy as Beijing did in 2016. If our BCA House View on the Fed is correct, a tepid Chinese effort to stimulate the domestic economy will fall short of lighting the flame of a global risk rally in 2019. Chart 11Compare Any Stimulus To Previous Efforts Compare Any Stimulus To Previous Efforts Compare Any Stimulus To Previous Efforts The BCA China Play Index, which in the past has tracked EM vs. DM equity outperformance, is sending mixed signals today (Chart 12). Enthusiasm for global risk assets has not been confirmed by the most China-sensitive plays. Chart 12Mixed Signals From China-Sensitive Plays Mixed Signals From China-Sensitive Plays Mixed Signals From China-Sensitive Plays Finally, there is the trade truce that should produce a trade deal. The logic is clear: President Trump sets aside the political constraints working against a deal and focuses on ensuring that he wins 2020 by avoiding a recession. The near bear market in the S&P 500 was a game changer that focused the White House on averting any further downside to markets and the economy from the trade war. But if the current rally proves that the selloff in December was a temporary pullback, the White House may be emboldened to play hard-to-get with China. After all, the electorate is generally supportive of getting tough on China (Chart 13) and there is no demand from either Trump voters or Democrats for a quick deal. The Fed pause and lower oil prices also give Trump some space to push negotiations a bit harder. Chart 13 Already there are leaks from the negotiations that the U.S. is asking for a lot from China, which could prolong the talks. This includes genuine structural changes to the economic relationship that would address long-standing U.S. concerns of forced technology transfers, intellectual property theft, and foreign investor access to the Chinese domestic market. It also includes U.S. demands that these changes be verifiable and enforceable. China is likely to balk at some of the U.S. demands, particularly if the U.S. is indeed pushing for regular reviews of China’s progress, a condition that implicitly creates a hierarchy between the two economies and would thus represent a loss of face for Beijing.3 Table 1 presents our latest expectations of where the U.S. and China will be on March 1. We assign only 10% each to “black and white” outcomes, a “Grand Compromise” and “No deal, with major escalation.” The remaining 80% is divided between “mushy” outcomes, including a 25% probability that negotiations simply continue. Table 1Updated U.S.-China Trade War Probabilities Witches' Brew: How Geopolitical Risks May Short-Circuit The Late-Cycle Rally Witches' Brew: How Geopolitical Risks May Short-Circuit The Late-Cycle Rally How would the market react to such uncertain outcomes? We think that almost anything other than a “Grand Compromise” would be greeted with limited relief, if not outright market correction. A vaguely positive meeting between Presidents Trump and Xi, and a memorandum of understanding, would not remove long-term risks in the relationship, especially if the parallel “tech war” is not resolved. On top of the ongoing U.S.-China negotiations, there is one remaining trade issue that investors should keep in mind: auto tariffs. The Section 232 investigation into whether auto imports are a national security threat is ongoing and U.S. authorities are expected to present their conclusions on February 17. We fear that the Trump administration could still stage a surprise and impose tariffs on auto imports. This is because the just-concluded NAFTA deal likely raised the cost of vehicle production within the trade bloc, necessitating import tariffs in order for the deal to make sense from President Trump’s set of political priorities. An extended truce with China could provide the opportunity. The Trump administration may not have the stomach for a long-term trade war with Europe, but the timing of this decision could upset the market’s perception of Trump’s commitment to free trade once again. Bottom Line: The conventional narrative is that global markets are experiencing a late-cycle rally, one that is worth playing given its usual duration and amplitude. This view rests on three pillars: that the Fed has backed off from tightening, that China is stimulating in earnest, and that the trade deal will produce a definitive outcome. We fear that all three pillars are shaky. First, the Fed is not easing. Its balance sheet contraction process, which is ongoing, is a form of tightening. And the U.S. economy remains healthy. As such, the expectation of a 12-month Fed pause is overly optimistic. Second, China is stimulating, but only tepidly. Third, “black and white,” definitive outcomes are unlikely in the U.S.-China negotiations. In fact, more protectionism could be around the corner if U.S.-China tech issues continue to flare or if the U.S. announces the conclusion of its investigation into auto imports. Geopolitical Factors To Monitor Aside from shaky pillars, markets will also have to contend with several uncertain geopolitical processes this year. While we are not necessarily bearish on each one, we are concerned that the collective investment community is overly bullish. Take Brexit. We agree with the conventional view that the chances of a no-deal Brexit outcome are below 10%. Political betting markets have only priced in an actual exit on March 29, which is in ink in British legislation, at just above 30% (Chart 14). Chart 14Online Betters Expect A Brexit Delay Online Betters Expect A Brexit Delay Online Betters Expect A Brexit Delay The problem is not with the conventional view but with its timing. While Prime Minister Theresa May will ultimately be forced to extend the Article 50 deadline, it may take a lot of brinkmanship and eleventh hour negotiations to do so. Getting from here – collective bullishness – to there – an actual extension of Article 50 – may require a downturn in GBP/USD or other U.K. assets. Furthermore, several scenarios could produce a downturn in GBP/USD (Diagram 1). For example, the Labour Party remains neck-and-neck with the Tories in the polls, despite being led by the most left-leaning leader since the 1970s. Although a new election that produces a Labour government would likely reduce the odds of Brexit eventually occurring, it would raise the odds of Corbyn pursuing unorthodox economic policy while also trying to negotiate his own version of Brexit with the EU. Diagram 1Brexit: The Path To Salvation Remains Fraught With Dangers Witches' Brew: How Geopolitical Risks May Short-Circuit The Late-Cycle Rally Witches' Brew: How Geopolitical Risks May Short-Circuit The Late-Cycle Rally The point is that it is tough to recommend that investors close their eyes and buy GBP/USD, no matter how cheap the currency may look, unless one has a very long time horizon and a high threshold for pain. The second issue where we take a more nuanced position is the ongoing U.S. executive-legislative standoff over the border. The government shutdown is only on pause until February 15. The House Democrats are demanding that a solution be found by Friday, February 8 if it is to be voted on in time. Meanwhile President Trump’s popularity is in the doldrums (Chart 15). His supporters note that President Reagan was even less popular at this point in his term, but that is because unemployment hit 10.4% in January 1983 (Chart 16). The grave risk for President Trump is that he is as unpopular as Reagan, even though unemployment is at 4% and the U.S. economy is on fire. Chart 15President Trump Is Unpopular... President Trump Is Unpopular... President Trump Is Unpopular... Chart 16...And It Can't Be Blamed On Unemployment ...And It Can't Be Blamed On Unemployment ...And It Can't Be Blamed On Unemployment As such, the real risk is not another shutdown, but rather political dysfunction in Congress that imperils the legislative process. The current two-year budget deal, which raised spending levels in January 2018, is set to expire when the FY2019 ends. Democrats and Trump have to come to an agreement to avert the “stimulus cliff” expected in 2020 (Chart 17). If they cannot conclude the border issue and the FY2019 appropriations, then Trump may declare a national emergency (or act unilaterally in other ways) and spark a new conflict with the courts. He could also threaten not to raise the debt ceiling in spring or summer. This is not an atmosphere in which a FY2020 deal looks very easy. Chart 17Stimulus Cliff Ahead Stimulus Cliff Ahead Stimulus Cliff Ahead Ultimately, we expect Democrats to succumb to the pressure from their voters for more spending. But a total failure to cooperate is a risk. Furthermore, the greatest political risk in the U.S. is that the 2020 election will not be contested on the same issues as in 2016: trade and immigration. Instead, income inequality is rearing its head, as Democratic candidates jostle for attention and as they test various messages on focus groups. If income inequality catches fire as the issue of 2020, we will know it soon. And it may begin to impact the markets as Democrats begin to campaign on, for instance, reversing President Trump’s income tax cuts. While the market may ignore headline election risks for some time, we do not think that non-financial corporates can do the same. Any hint that President Trump’s pro-business policies will be reversed could send shivers down the spines of CEOs and negatively impact capex intentions, hurting the real economy well before the next election. Finally, there is the issue of foreign policy. President Trump has abandoned his maximum pressure tactic on Iran and has begun withdrawing the remaining troops in the Middle East. These trends are likely to continue in 2019 as President Trump focuses on China and lesser issues like Venezuela. There is one important area of alignment between him and the defense and intelligence community, notwithstanding recent scuffles: less focus on the Middle East means more focus on Asia and specifically China. However, President Trump is facing a dilemma. Despite an extraordinary economic performance, his popularity remains in the doldrums. When faced with similar situations in the past, presidents far more orthodox than Trump have sought relevance abroad, by means of military interventions. A convenient opportunity has presented itself in Venezuela, where a revolution against Chavismo could give the U.S. an opening to intervene. On paper, we see how such a scenario could look appealing for a quick, and relatively painless, intervention. The problem is that it could also get messy and, in the analysis of BCA’s Commodity & Energy Strategy, raise oil prices to nearly $100 per barrel by mid-year if a total loss of Venezuelan production ensues (Chart 18). This is a non-negligible risk. Chart 18A Venezuela Collapse Could Send Brent Crude Prices Toward $100/Bbl A Venezuela Collapse Could Send Brent Crude Prices Toward $100/Bbl A Venezuela Collapse Could Send Brent Crude Prices Toward $100/Bbl Bottom Line: Geopolitical risks still abound. We are not alarmist. However, there is little reason to believe that Brexit, U.S. polarization, U.S.-China tensions, or a potential U.S. intervention in Venezuela will end painlessly for the market. An unpopular U.S. president is seeking to remain relevant and a global populist wave is continuing to create unorthodox and anti-establishment policy prescriptions. Given that the current rally is supported by three shaky pillars, any one of these geopolitical risks could catalyze a relapse, the history of late-cycle rallies be damned.   Marko Papic, Senior Vice President Chief Geopolitical Strategist marko@bcaresearch.com Matt Gertken, Vice President Geopolitical Strategy mattg@bcaresearch.com   Footnotes 1      Please see BCA U.S. Investment Strategy Weekly Report, “Late-Cycle Blues,” dated October 29, 2018, available at usis.bcaresearch.com. 2      Please see BCA Global Investment Strategy Weekly Report, “Patient Jay,” dated January 18, 2019, available at gis.bcaresearch.com. 3      Please see Reuters, “Exclusive: U.S. demands regular review of China trade reform,” dated January 18, 2019, available at reuters.com.   Geopolitical Calendar

Highlights Portfolio Strategy Chinese reflation, the ongoing global capex upcycle, and the Fed induced cap on the greenback with the knock-on effect of higher commodity prices, all signal that it still pays to overweight S&P cyclicals at the expense of S&P defensives.  Sustained EM stock outperformance, a soft U.S. dollar, improving semi equipment operating metrics, along with compelling relative valuations and technicals, all suggest that there are high odds that the recent semi equipment run up has more upside.   Recent Changes There are no changes in the portfolio this week. Feature The SPX consolidated the 350 point advance since the Christmas Eve trough last week, setting the stage for a durable advance in the coming months. The Fed stood pat last Wednesday, and signaled a much more dovish policy stance going forward. Chairman Powell was clearly humbled by last December’s convulsing equity market and abrupt tightening in financial conditions. On that front, in the latest FOMC statement the explicit mention of patience is significant: “the Committee will be patient as it determines what future adjustments to the target range for the federal funds rate may be appropriate”. A definitively more dovish Fed, which will help restrain the greenback, remains one of the three key catalysts for a durable equity market advance as we have highlighted in recent research.1 Encouragingly, our proprietary Equity Capitulation Indicator (ECI) has bottomed at two standard deviations below the historical mean (Chart 1). Over the past two decades, such a depressed level in our ECI has marked previous equity market troughs including the early-2016, 2011, 2002 and 1998 iterations. Only the GFC episode was lower, falling to three standard deviations below the mean. Clearly the late-December selling frenzy registers as another investor capitulation point and, if history at least rhymes, more gains are in store for the broad equity market. Chart 1Capitulation Capitulation Capitulation Chart 2 shows some other measures of breadth that corroborate our ECI’s message: investors hit the panic button and exited equities in droves in Q4. The upshot is that with selling exhausted, stocks can now stage a durable recovery as long as profits continue to expand. As a reminder, the continuation of the earnings juggernaut is the second key catalyst we identified two weeks ago.2 Midway through earnings season, SPX EPS have held up well with growth approaching 16%. For calendar 2019 we expect mid-single digit EPS growth in line with the signal from our macro driven S&P 500 EPS growth model (please refer to Chart 4 from the mid-January Weekly Publication).3 Chart 2Selling Is Exhausted Selling Is Exhausted Selling Is Exhausted A positive resolution to the U.S./China trade spat is the third catalyst we highlighted recently in order for equities to break out to fresh all-time highs.4 Related to this, China’s reflation efforts are equally important. On that front, news of quasi QE from the PBOC suggests that the Chinese authorities remain committed to injecting liquidity into their economy.5 Already, the PBOC balance sheet, with over $5.5tn in assets, is expanding anew. Empirical evidence suggests that SPX momentum and the ebb and flow of the PBOC balance sheet are joined at the hip, and the current message is positive (second panel, Chart 3). Chart 3Heed The PBoC Message Heed The PBoC Message Heed The PBoC Message Beyond the PBOC balance sheet expansion, the Chinese six-month credit impulse is also in a sling shot recovery. This Chinese credit backdrop is enticing and moves more or less in tandem with the SPX six-month impulse (top panel, Chart 4). Chart 4Reflating Away Reflating Away Reflating Away Two forces explain these relationships. First, China’s rise to become the second largest economy in the world along with its insatiable appetite for commodities and durable goods. Second, 40% of S&P 500 sales are international and an increasing share now originates in emerging markets in general and in China in particular. Keep in mind that the S&P cyclicals/defensives ratio is not only a high beta play on the SPX itself (top panel, Chart 3), but also an S&P global versus domestic gauge. Thus, both of these Chinese indicators also enjoy a positive correlation with the cyclicals vs. defensives tilt (bottom panels, Charts 3 & 4). With that in mind, this week we are drilling deeper into why we continue to prefer S&P cyclicals over S&P defensives and also highlight a highly cyclical index we went overweight in mid-December that has gone parabolic. Double Down On Cyclicals Vs. Defensives Early-October 2017 marks the initiation of our cyclical vs. defensive preference. Initially, this tilt jumped and peaked in mid-2018 returning 18% since inception. Since then, it has given up all of those gains and then some before troughing with the market on Christmas Eve, suffering a 6% drop since inception. Currently, the ratio has moved full circle and is back to where it was when we first recommended this portfolio bent (Chart 5). Chart 5Full Circle Full Circle Full Circle Should investors commit capital to this tilt at this stage of the cycle and given the current global macro backdrop? The short answer is yes. Charts 3 & 4 show that China’s reflation efforts and the fate of the S&P cyclicals/defensives ratio are closely correlated. In addition to the PBOC’s expanding balance sheet and rising Chinese credit impulse, Chinese monetary easing also benefits S&P cyclicals at the expense of S&P defensives. The Chinese reserve requirement ratio (RRR) has plummeted to the lowest point since the GFC and Chinese interest rates are also plumbing multi-year lows (RRR shown inverted, top panel, Chart 6). Chart 6China Flashing Green China Flashing Green China Flashing Green Tack on a resurgent currency with the CNY briefly breaking 6.70 with the U.S. dollar, and factors are falling into place for a playable rally in the cyclicals/defensive ratio. Likely, the Chinese are trying to appease President Trump by underpinning the yuan, but the Fed’s recent more dovish stance on interest rate hikes is also pushing the greenback lower. Taken together, this is a boon for the commodity exposed U.S. cyclicals that also garner a significant share of their sales from abroad (bottom panel, Chart 6). Commodity prices troughed last September, staying true to their leading properties and have been in recovery mode ever since (top panel, Chart 7). Now that the Fed has capped the U.S. dollar, more gains are in store for commodities and that is a boon for commodity producers’ top line growth prospects. Chart 7Capex Remains Healthy Capex Remains Healthy Capex Remains Healthy The demand backdrop is also enticing at the current stage of the business cycle, not only domestically, but also in China. Capital outlays remain upbeat and despite some recent turbulence, U.S. capex intentions are near multi-year highs (third panel, Chart 7). In China, recent piece meal fiscal easing announcements are far from negligible; already infrastructure spending has jumped after contracting late last year (second panel, Chart 7). Were these announcements to get supplemented by a bigger and more comprehensive package, then commodity-levered equities will excel further. A look at the relative balance sheet health of cyclicals versus defensives is revealing. Cyclicals are paying down debt and their cash flow continues to improve, still recovering from the late-2015/early 2016 global manufacturing recession. On the flipside, defensives are piling on debt. All four safe haven sectors have been degrading their balance sheets (relative net debt-to-EBITDA shown inverted, middle panel, Chart 8). Interest coverage sends a similar message: cyclicals are in excellent health both in absolute terms and compared with defensives (top panel, Chart 8). Chart 8B/S Improvement Continues B/S Improvement Continues B/S Improvement Continues Sell-side analysts have not yet taken notice of the macro tide that is turning in favor of cyclicals over defensives. Relative forward profit growth has collapsed to nil and net EPS revisions are at previous nadirs (fourth & fifth panels, Chart 9). Chart 9Oversold And Unloved Oversold And Unloved Oversold And Unloved In sum, if our thesis pans out that China will continue to reflate, global capex will remain vibrant, the greenback will drift lower (U.S. dollar shown inverted, top panel, Chart 9) courtesy of a dovish Fed that will push the broad commodity complex higher, then a significant valuation rerating looms for the cyclicals/defensives tilt (second panel, Chart 9). Bottom Line: Continue to the prefer S&P cyclicals to S&P defensives. We also reiterate our recent long S&P materials/short S&P utilities pair trade.6 Semi Equipment: Buy Into Strength In mid-December we boosted the S&P semi equipment index to overweight from underweight and since then this niche chip subindex has outperformed the broad market by 17%.7 Semi equipment stocks are high beta (bottom panel, Chart 10) and, while we are recommending to buy into strength, from a portfolio risk management perspective, today we are also setting a trailing stop at the 10% return mark in order to protect profits in this tactical (three-to-six month time horizon) position. Chart 10Buy Into Strength... Buy Into Strength... Buy Into Strength... These high-octane highly-cyclical tech stocks move in lockstep with other volatile asset classes. Rebounding emerging market (EM) stocks and FX confirm the S&P semi equipment breakout, and signal additional gains in the coming months (Chart 11). Not only do they share the high-beta status, but also semi equipment stocks garner 90% of their sales outside U.S. shores and 21% of total revenues come from China (please refer to Table 3 in our December 17, 2018 Weekly Report). Thus, the tight inverse correlation with the greenback and positive correlation with the outperforming EM stocks comes as no surprise (Chart 11). Chart 11...But Expect Heightened Vol ...But Expect Heightened Vol ...But Expect Heightened Vol Importantly, Taiwan and Korea are chip manufacturing hubs and semi equipment stocks are levered plays on the macro backdrops of these two economies. Recent data suggests that a turn is in the making in two key indicators in these countries, respectively. Taiwanese tech capex has likely troughed at a depressed level (middle panel. Chart 12), and Korean electronic components manufacturing capacity is now contracting for the first time since late-1997 (bottom panel, Chart 12). The latter is significant as this abrupt and sizable reining in of productive capacity will soon help arrest the fall in chip prices, which serves as an excellent pricing power proxy for the semi equipment industry. Chart 12Green Shoots Green Shoots Green Shoots Historically, relative forward profit growth and DRAM price momentum are joined at the hip. Therefore, were DRAM prices to exit deflation on the back of constrained Korean capacity, that would be a boon for relative profit prospects (second panel, Chart 13). Chart 13Analysts Have Thrown In The Towel Analysts Have Thrown In The Towel Analysts Have Thrown In The Towel Despite these marginal positive developments, sell-side analysts’ pessimism reigns supreme. Industry revenue and profit growth expectations trail the broad market by a wide margin and net EPS revisions remain as bad as they get. The upshot is that these lowered profit and sales growth bars will be easy to surpass in 2019 (Chart 13). With regard to technicals and valuations, oversold conditions bounced, as we posited in mid-December using history as a guide, but still remain depressed (middle panel, Chart 14). Valuations are compelling with the S&P semi equipment forward P/E trading at a roughly 40% discount to the overall market (fourth panel, Chart 13). Chart 14Technicals Remain Depressed Technicals Remain Depressed Technicals Remain Depressed Finally, earnings season has revealed that the bifurcated semiconductor market has staying power with semi equipment stocks (we are overweight) outperforming their ailing semi producer brethren (we remain underweight). Netting it out, sustained EM stock outperformance, a soft U.S. dollar, improving industry operating metrics, along with compelling relative valuations and technicals, all suggest that there are high odds that the recent semi equipment run up has more upside. Bottom Line: Maintain the overweight stance in the S&P semi equipment index for a while longer, but set a trailing stop at the 10% relative return mark in order to protect profits in this tactical (three-to-six month time horizon) position.

Highlights After rising for thousands of years, human intelligence has begun to decline in developed economies. This can be seen in falling IQ scores and a decline in math and science test scores. Environmental factors appear to account for the bulk of this decline, but no one knows what these factors are. If left unchecked, falling intelligence will severely undermine productivity growth. This could lead to lower equity multiples, larger budget deficits, and ultimately, much higher government bond yields. Technological advances, particularly in the genetic realm, promise to radically raise IQs. In a complete abandonment of its one-child policy, China will combine these controversial technologies with pro-natal measures in order to boost sagging birth rates. The coming Eugenic Wars will be one of the most important economic and geopolitical developments of the 21st century. Feature Part 1: What The Tame Fox Says In 1959, a Soviet scientist named Dmitry Belyaev embarked on an ambitious experiment: to domesticate the silver fox. A geneticist by training, Belyaev wanted to replicate the process by which animals such as cats and dogs came to live side-by-side with humans. It was a risky endeavor. The Soviets had essentially banned the study of Mendelian genetics in favor of the blank slate ideology that is popular in progressive circles today. Belyaev persevered. Working under the guise of studying vulpine physiology, he selected foxes based on only one trait – tamability. Less than 10% of foxes made it to the subsequent generation, with the other 90% being sent off to fur farms. By the fourth generation, the changes were undeniable. Rather than fleeing humans, the foxes sought out their attention with no prompting whatsoever. They even wagged their tails and whined and whimpered like dogs do. The tame foxes also displayed physical changes. Their ears flopped over. Their snouts became shorter and their tails stood upright. “By intense selective breeding, we have compressed into a few decades an ancient process that originally unfolded over thousands of years,” wrote Lyudmila Trut, who began as Belyaev’s assistant and took over the project when her boss died in 1985.  Genetically Capitalist? Evolution can broadly proceed in two ways. The first way is through random mutations. This form of evolution, which scientists sometimes refer to as genetic drift, can take thousands of years to yield any discernable changes. The second way is through natural selection, a process that exploits existing variations in genetic traits. As the Russian fox experiment illustrates, evolution driven by selective pressures (either natural or artificial) can occur fairly quickly. Did selective pressures manifest themselves in human evolution in the lead up to the Industrial Revolution? Did humans, in some sense, domesticate themselves? In his book, A Farewell To Alms, economic historian Gregory Clark argued in the affirmative. Clark documented that members of skilled professions in Medieval England had twice as many surviving children as unskilled workers (Chart 1). Indeed, the fledgling middle class of the time had even more surviving children than the aristocracy, who were often out fighting wars. As a result, the wages of craftsmen declined by a third relative to laborers between 1200 and 1800, implying that the supply of skilled labor was growing more quickly than the demand for skilled workers over this period. Chart 1 In subsequent work, Clark and Cummins argued that the spread of bourgeois values across pre-industrial England was more consistent with a model of genetic transmission than a cultural one (see Box 1 for details). Similar developments occurred in other parts of the world. For example, in China, the gateway into the bureaucracy for a thousand years was the highly competitive imperial exam. Xi Song, Cameron Campbell, and James Lee showed that high-status men had more surviving children during the eighteenth- and nineteenth-centuries (Chart 2).1 Chart 2 The 10,000 Year Explosion Stephen Jay Gould famously said that “There’s been no biological change in humans in 40,000 or 50,000 years. Everything we call culture and civilization we’ve built with the same body and brain.” Gould was wrong. Data from the International HapMap Project show that human evolution accelerated by 100-fold starting around 10,000 years ago (Chart 3). Chart 3 In their book The 10,000 Year Explosion: How Civilization Accelerated Human Evolution, Gregory Cochran and the late Henry Harpending explained why evolution sped up so rapidly.2 The advent of agriculture led to a surge in population levels. This, in turn, increased the absolute number of potentially beneficial genetic mutations that could be subject to selection effects. Farming and the rise of city states also completely reshaped the environment in which people lived. Basic biology teaches us that environmental dislocations of this kind tend to generate selective pressures that cause evolution to accelerate. John Hawks, professor of anthropology and genetics at the University of Wisconsin-Madison, put it best: “We are more different genetically from people living 5,000 years ago than they were different from Neanderthals.” Many of the changes to our genomes relate to diet and diseases. The various genetic resistances that people have built up to malaria are all less than 10,000 years old. Mutations to the LCT gene, which confers lactose tolerance into adulthood, occurred independently in three different geographical locations: one in East Asia, one in the Middle East, and one in Africa. The Middle Eastern variant was probably responsible for the rapid enlargement of the Indo-European language group, which now stretches from India to Ireland. The African variant likely facilitated the Bantu expansion, which started near the present-day border of Nigeria and Cameroon, and then spread out across almost all of sub-Saharan Africa. Evolution Of The Human Brain About half of the genes in the human genome regulate some aspect of brain function. Given the rapid acceleration in evolution, it would be rather surprising if our own brains had not been affected. And indeed, there is plenty of evidence that they were. The frontal lobe of the brain has increased in size over the past 10,000 years. This is the part of the brain that regulates such things as language, memory, and long-term planning. Testosterone levels have also declined. That may explain the steady reduction in violent crime rates (Chart 4). Chart 4 We know that certain genes that are associated with higher intelligence have been under recent selective pressure. For example, the gene that leads to torsion dystonia – a debilitating movement disorder – appears to have increased in frequency. Why would a gene that causes a known disease become more widespread? The answer is that individuals who have this particular mutation tend to have IQs that are around 10-to 20-points above the population average. Why IQ Matters IQ has a long and contentious history. Yet, despite numerous efforts to jettison the concept, it has endured for one simple reason: It has more predictive power than virtually anything else in the psychological realm. A simple 30-minute IQ test can help predict future educational attainment, job performance, income, health, criminality, and fertility choices (Table 1 and Chart 5). IQ even predicts trader performance!3 Table 1What IQ Predicts (Results From Meta-Analyses) The Most Important Trend In The World Has Reversed And Nobody Knows Why The Most Important Trend In The World Has Reversed And Nobody Knows Why   Chart 5 Like most physiological traits, IQ is highly heritable.4 The genetic contribution to IQ increases from 20% in early childhood to as high as 80% by one’s late teens and remains at that level well into adulthood.5 This makes IQ almost as heritable as height (Chart 6). Chart 6 Although there is a great deal of variation among individuals, on average, more intelligent people earn higher incomes (Chart 7). If the same relationship existed in the pre-industrial era, as seems likely, then human intelligence probably increased in a way that facilitated the economic explosion that we associate with the Industrial Revolution. The stunning implication is that the emergence of the modern era was a question of “when, not if.” Chart 7 Part 2: The Flynn Effect By the late-19th century, it had become clear that the rich were no longer having as many children as the poor. This realization, together with the growing popularity of Darwin’s theories, helped galvanize the eugenics movement. Contrary to popular belief, this movement was not a product of the far-right. In fact, the most vocal proponents of eugenics were among the progressive left. John Maynard Keynes, for example, served as the Director of the British Eugenics Society between 1937 and 1944. Yet, a funny thing happened on the road to idiocracy: The concerns of eugenicists did not come to pass. Rather than becoming dimmer, people became smarter. This phenomenon is now known as the Flynn Effect, named after James Flynn, a psychologist who was among the first to document it. Chart 8 shows the evolution of IQ scores in a sample of countries between 1940 and 1990. The average country recorded IQ gains of three points per decade over this period, a remarkably large increase over such a relatively short period of time. Chart 8 Explaining The Flynn Effect The Flynn Effect must have been entirely driven by environmental factors since genetic factors – namely the tendency of less-educated people to have more children, and to have them at an earlier age – would have reduced average IQs over the past two hundred years. But how could environmental factors have played the dominant role in light of the strong role of genes discussed above? The answer was proposed by geneticist Richard Lewontin in the 1970s. Lewontin suggested imagining a genetically-diverse sack of seed corn randomly distributed between two large identical fields. One field had fertilizer added to it while the other did not. Genetic variation would explain all of the differences in the height of corn stalks within each field, while environmental factors (the addition of fertilizer) would explain all of the difference in the average height of corn stalks between the two fields. This logic explains why genes can account for the bulk of the variation in IQs within any demographic group, while environmental effects may explain most of the variation across groups, as well as why average scores have changed over time. And what environmental effects are these? The truth is that no one really knows. Plenty of theories have been advanced, but so far there is still little consensus on the matter. Bigger, Healthier Brains It has long been known that learning increases the amount of grey matter in the brain. For example, a recent study showed that the hippocampi of London taxi drivers tend to be larger due to the need for drivers to memorize and navigate complex routes.6 The emergence of modern societies likely kicked off a virtuous circle where the need to solve increasingly complex tasks forced people to hone their learning skills, leading to higher IQs and further technological progress. The introduction of universal primary education amplified this virtuous circle. Better health undoubtedly helped as well. Early childhood diseases reduce IQ by diverting the body’s resources away from mental development towards fighting off infections. There is a strong correlation between measured IQ and disease burden across countries (Chart 9). A number of studies have documented a strong relationship between the timing of malaria eradication in the U.S. and other parts of the world and subsequent observed gains in childhood IQs.7 Chart 9 Brain size and IQ are positively correlated. Forensic evidence from the U.S. suggests that the average volume of adult human skulls has increased by 7% since the late 1800s, or roughly the size of a tennis ball.8 Part 3: The End Of A 10,000 Year Trend The problem with environmental effects is that they eventually run into diminishing returns. This appears to have happened with the Flynn Effect. In fact, not only does the recent evidence suggest that the Flynn Effect has ended, but the data suggest that IQs are starting to decline. Chart 10 shows that average math and science test scores fell in the OECD’s Program For International Scholastic Achievement (PISA) between 2009 and 2015, the latest year of the examination. The drop in math and science test scores has been mirrored in falling IQ scores. Flynn observed a decade ago that IQs of British teenagers were slipping.9 Similar results have been documented in France, the Netherlands, Germany, Denmark, and most recently, Norway. Chart 10 The Norwegian results, published last year, are particularly noteworthy.10 Bernt Bratsberg and Ole Rogeberg examined three-decades worth of data on IQ tests of Norwegian military conscripts. Military duty has been mandatory for almost all men in Norway since 1814, which means that the study’s authors were able to collect comprehensive data on most Norwegian men and their fathers.  Their paper clearly shows that IQ peaked with the generation born in the mid-1970s and declined by about five points, or one-third of a standard deviation, for the one born in 1990 (Chart 11). For the first time in recorded history, Norwegian kids today are not scoring as well as their parents. Chart 11 A Mystery What caused the sudden reversal of the Flynn Effect in Norway and most other developed economies? Nobody knows. We can, however, offer three possible theories: New Technologies For much of human history, rising intelligence and technological innovation were complementary processes, meaning that the smartest people were the ones who could best exploit the new technologies that were coming their way. Moreover, as noted above, even those who were less gifted benefited from the mental stimulation that a technologically advanced society provided. It remains to be seen how future technological advances such as generalized AI will affect human intelligence, but recent technological advances seem to have had a dumbing down effect.11 For example, the GPS has obviated the need for people to navigate unfamiliar locations, thus blunting the development of their visuospatial skills. Modern word processors have made spelling skills less important. Having all the information in the world just a click away is a wonderful thing, but it has reduced the need for our brains to retain and codify what we learn. Meanwhile, the constant bombardment of information to which we are subject has made it difficult to concentrate on anything for long. How many youth today can read a report of this length without checking their Facebook feed multiple times? My guess is not many. Diminishing Returns To Education The ability to take young bright minds, who would have otherwise spent their lives doing menial labor, and provide them with an education was probably the greatest tailwind to growth that the 20th century enjoyed. There is undoubtedly still scope to continue this process, but the low-hanging fruit have been picked. Educational attainment has slowed dramatically in most of the world (Chart 12). Economist James Heckman estimates that U.S. high-school graduation rates, properly measured, peaked over 40 years ago.12 Chart 12 Despite billions of dollars spent, efforts to improve school performance have generally fallen flat. A recent high-level report by the U.S. Department of Education concluded that “The panel did not find any empirical studies that reached the rigor necessary to determine that specific turnaround practices produce significantly better academic outcomes.”13 This gets to a point that most parents already know, which is that when people talk about “bad schools,” they are really talking about “bad students.” Deteriorating Health Better health probably contributed to the Flynn Effect. But is it possible to have too much of a good thing? More calories are welcome when people are starving, but today’s calorie-rich, nutrient-poor diets have led to a surge in obesity rates. A clean environment reduces the spread of germs, but it also makes children hypersensitive to foreign substances. Following German reunification, researchers observed that allergies were much more common among West German children than their Eastern peers, presumably because of the West’s more salubrious environment.14 All sorts of weird and concerning physiological changes are occurring. Sperm counts have fallen by nearly 60% since the early 1970s.15 Testosterone levels in young men are dropping. Among girls, the age of first menarche has declined by two years over the past century.16 Are chemical agents in the environment responsible? If they are, what impact are they having on cognitive development? Nobody knows. Reported mental illness is also on the rise. The share of U.S. teenagers with a reported major depressive episode over the prior year surged by over 60% between 2010 and 2017 (Chart 13). The fraction of young adults that made suicide plans nearly doubled.17 More than 20% of U.S. women over the age of 40 are on antidepressants.18 Five percent of U.S. children are receiving ADHD medication.19 Chart 13 Implications For Economic Growth And Asset Markets So far, the reversal of the Flynn Effect has been largely confined to the developed economies. Test scores are still rising in the developing world, albeit from fairly low levels. For example, two recent studies have documented significant IQ gains in Kenya and Brazil.20 In the poorest countries, opportunities for improving health abound. Even small steps such as fortifying salt with iodine (which costs about five cents per person per year) have been shown to boost IQ by nearly one standard deviation.21 Measures to reduce inbreeding are also likely to boost IQ scores.22 Yet, we should not underestimate the importance of falling cognitive skills in developed economies. Chart 14 shows that there is a clear positive correlation between student score on math and science and per capita incomes. Chart 14 Most technological innovation still takes place in developed economies. There is an extremely tight relationship between visuospatial IQ and the likelihood of becoming an inventor (Chart 15). Since IQ is distributed along a bell curve, a 0.1 standard deviation drop in IQs across the entire distribution will result in an 8% decline in the share of people with IQs over 100, a 14% decline in those with IQs over 115, and a 21% decline in those with an IQ over 130 (by convention, each standard deviation on an IQ test is worth 15 points). Chart 15 Falling IQs could result in slower productivity growth, which could further strain fiscal balances. Lower IQs are also associated with decreased future orientation.23 People who live for the moment tend to save less. A decline in savings would push up real rates, leading to less capital accumulation. History suggests that a deceleration in productivity growth and higher real rates will put downward pressure on equity multiples (Chart 16). Chart 16Equity Multiples Tend To Fall When Real Rates Rise And Productivity Growth Declines Equity Multiples Tend To Fall When Real Rates Rise And Productivity Growth Declines Equity Multiples Tend To Fall When Real Rates Rise And Productivity Growth Declines Part 4: Generation E For 200 years, the environmentally-driven Flynn Effect disguised the underlying genetically-driven decline in IQs that began not long after the dawn of the Industrial Revolution. Flynn has acknowledged this himself, noting at the 2017 International Society For Intelligence Research Conference that “I have no doubt that there has been some deterioration of genetic quality for intelligence since the late Victorian times.”24 Now that the Flynn Effect has reversed, both genes and the environment are working together to reduce cognitive abilities in developed economies. This means that the most important trend in the world – a trend that allowed the human population to increase during the Malthusian era and later allowed output-per-worker to soar following the Industrial Revolution – has broken down. Yet, there may be another twist in the story – one that began just a few months ago: the first members of Generation E were born. E Is For Edited ... Or Eugenics Lulu and Nana will be like most other children, but with one key difference: They will be the first humans ever to have their genomes edited through a procedure know as CRISPR-Cas9. Rogue Chinese scientist He Jiankui deactivated their CCR5 gene, which the HIV virus uses as a gateway into the body. His actions were rightfully condemned around the world for endangering the twins’ health by using a procedure that has not yet been fully vetted in animal studies, let alone in human trials (Lulu and Nana’s father is HIV+ but it is debatable whether the children were at an elevated risk of infection). He Jiankui remains under house arrest at the university where he worked. But whatever his fate, the dam has been broken. For better or for worse, the era of personal eugenics has arrived. The Return Of The Silver Fox It is easier to delete a gene than to add one. It is even more difficult to swap out a large number of genes in a way that achieves a predictable outcome. Thus, the successful manipulation of highly polygenic traits such as intelligence – traits that are linked to hundreds of different genes – may still be decades away.25 Predicting a trait is much simpler than modifying it, however. The cost of sequencing a human genome has fallen by more than 99% since 2001 (Chart 17). Start-up company Genomic Prediction has already developed a test for fertilized embryos for IVF users that predicts height within a few centimetres and IQ with a correlation of 0.3-to-0.4, roughly as accurate as standardized tests such as the SAT or ACT.26 Other companies are following suit.27 Chart 17 Some will recoil in horror at the prospect of selecting prospective children in this manner. They will argue that such technologies, beyond being simply immoral, will widen social inequality between those who can afford them and those who cannot. Others will counter that screening embryos for certain traits is not that dissimilar to what people already do with prospective romantic partners. They will also point out that mass usage of these technologies will drive down prices to the point that even poor people will be able to access them, thus giving low IQ parents the chance to have high IQ kids. They might also note that such technologies may be the only way to reverse the ongoing accumulation of deleterious mutations within the human germline that has been the unintended by-product of the proliferation of life-saving medicines.28 We will not wade into this thorny debate, other than to note that there will be huge incentives for people to avail themselves of these technologies. The Coming Eugenic Wars And not just individuals either – governments too. While the initial impact of eugenic technologies will be small, the effects will compound over time. Carl Shulman and Nick Bostrom estimate that genetic screening could boost average IQs by up to 65 points in five generations (Table 2). Table 2A Poisoned Chalice? Genetic Screening Can Raise IQ The Most Important Trend In The World Has Reversed And Nobody Knows Why The Most Important Trend In The World Has Reversed And Nobody Knows Why China has been investing heavily in genetic technologies. As Geoffrey Miller has argued, China’s infatuation with eugenics spans into the modern day.29 Like most other countries, fertility in China is negatively correlated with IQ. Mingrui Wang, John Fuerst, and Jianjun Ren estimate that China is currently losing nearly one-third of a point in generalized intelligence per decade, with the loss having accelerated rapidly between the 1960s and mid-1980s.30 The decline in the genetic component of Chinese IQs is coming at a time when the population itself is about to shrink. According to the UN’s baseline forecast, China will lose 450 million working-age people by the end of the century (Chart 18). Meanwhile, the country is saddled with debt, the result of an economic model that has, for decades, recycled copious household savings into debt-financed fixed-investment spending in an effort to shore up domestic demand. Chart 18 The authorities may be tempted to tackle all three problems simultaneously by adopting generous pro-natal measures – call it the “at least one-child policy”– which increasingly harnesses emerging eugenic technologies. The resulting baby boom would strengthen domestic demand, thus making the economy less dependent on exports, while ensuring China’s long-term geopolitical viability. The Eugenic Wars are coming, and they will be unlike anything the world has seen before.   Peter Berezin, Chief Global Strategist Global Investment Strategy  peterb@bcaresearch.com     Box 1  The Diffusion Of Bourgeois Values: Culture Or Genes? Higher-income people had more surviving children in the centuries leading up to the Industrial Revolution. Real per capita income was broadly stable during this period. This implies that there must have been downward social mobility, with sons, on average, being less wealthy than their fathers. This downward mobility, in turn, spread the characteristics of higher-income people across the broad swathe of society. What were these characteristics? Cultural values that emphasized thrift, diligence, and literacy were undoubtedly part of what was passed on to future generations. But surprisingly, it also appears that genetic transmission played an important, and perhaps pivotal, role.  Models of genetic transmission make very concrete predictions about the correlations in economic status that one would expect to see among relatives. Biological brothers share 50% of their genes, as do fathers and sons. Likewise, first cousins share 25% of their genes, the same as grandfathers and sons. These facts yield two testable predictions: The first is that the correlation coefficient on status measures such as wealth, occupation, and education should be the same for relatives that share the same fraction of genes such as sibling pairs and father-son pairs. Box Chart 1 shows that this is borne out by the data. The second prediction is that the correlation between status and genetic distance should follow a linear trend so that, for example, the correlation in wealth among brothers is twice that of first cousins and four times that of second cousins. Box Chart 2 shows that this is also borne out by the data. Other evidence supports the importance of genes in the transmission of status across generations. The correlation in measures such as wealth, education, and occupation is much higher among identical twins than fraternal twins. Adopted children turn out to be more similar to their biological parents on these measures when they reach adulthood than their adopted parents, even when the children have never met their biological parents. The parent-child correlation also remains the same regardless of family size, suggesting that spreading the same resources over more children may not harm life outcomes to any discernible degree, at least on the measures listed above.

There is no consensus on what causes it, but it probably reflects a number of factors: 1) It may take some children longer than normal to reach full intellectual maturity. Testing their IQs at a young age will result in scores that are lower than those expected based on their parents’ IQs. The opposite is true for children whose IQs increase relatively quickly in young age, but possibly top out earlier; 2) Environmental effects are probably more important in young age when a child’s brain is still quite malleable; 3) Self-reinforcing gene-environment interactions tend to increase with age. Children do not have much control over their environment, but as they get older, they will seek out activities that are more in keeping with their genetic predispositions. For example, a studious child may pursue a career that reinforces their love of learning. 6       "Cache Cab: Taxi Drivers' Brains Grow to Navigate London's Streets," Scientific American, (December 2011). 7       Atheendar Venkataramani, “Early Life Exposure to Malaria and Cognition in Adulthood: Evidence from Mexico,” Journal of Health Economics 31:5, (July 2012): 767-780; Hoyt Bleakley, “Health, Human Capital and Development,” Annual Review of Economics 2, (March 2010): 283-310; Hoyt Bleakley, “Malaria Eradication in the Americas: A Retrospective Analysis of Childhood Exposure,” American Economic Journal: Applied Economics 2, (April 2010): 1-45. 8       “Anthropologists Find American Heads Are Getting Larger,” ScienceDaily, (May 2012). 9       “British Teenagers Have Lower IQs Than Their Counterparts Did 30 Years Ago,” The Telegraph, (February 2009). 10     Bernt Bratsberg and Ole Rogeberg, “Flynn Effect And Its Reversal Are Both Environmentally Caused,” Proceedings of the National Academy of Sciences 115:26, (June 2018): 6674-6678. 11     On the face of it, artificial intelligence would appear to be a substitute for human intelligence. Many applications of AI would undoubtedly have this feature, especially those that allow computers to perform complex mental tasks that humans now must do. However, there are several ways that AI may eventually come to complement human intelligence. First, and most obviously, AI could be used to augment human capabilities either directly by hardwiring it into our brains, or indirectly through the development of drugs or genetic techniques which improve cognition. Second, looking further out, the benefits of highly intelligent AI systems would be limited if humans did not possess the requisite intelligence to understand certain concepts that are currently beyond our mental reach. No matter how well intentioned, trying to explain string theory to a mouse is not going to succeed. There are probably a multitude of ideas that AI could reveal that we simply cannot comprehend at current levels of human intelligence. 12     James Heckman and Paul La Fontaine, “The American High School Graduation Rate: Trends and Levels,” The Review of Economics and Statistics 92:2, (May 2010): 244–262. 13     “Turning Around Chronically Low-Performing Schools,” The Institute of Education Sciences (IES), (May 2008). 14     E. von Mutius, F.D.

Feature Half Way Back Since BCA went overweight global equities in late December, the MSCI ACWI index has rallied by 8% and the S&P 500 is back to only 8% off its September historical high. So far, this has been little more than a technical rally from the extreme oversold position in Q4. But with U.S. economic growth still resilient, earnings likely to grow healthily again this year (albeit more slowly than in 2018), and the valuation of risk assets (both equities and credit) no longer a headwind, we expect the rally to continue for some time, and so reiterate our overweight on equities. Recommendations Monthly Portfolio Update Monthly Portfolio Update True, there have been some disappointments in U.S. data in recent weeks. In particular, the December manufacturing ISM fell sharply to 54.3 from 59.3, raising fears that the U.S. is starting to decelerate in line with other regions (Chart 1). But the ISM may have been affected by the government shutdown and, overall, U.S. data still look solid, with the Citigroup Economic Surprise Index beginning to rebound, and stronger than in other regions (Chart 2). The residential housing market, which was exhibiting signs of stress last year, with existing home sales -6.4% YoY in December, is showing the first signs of stabilization, helped by mortgage interest rates that are now 50 BPs off their recent peak (Chart 3). Chart 1How Worrying Is The U.S. Slowdown? How Worrying Is The U.S. Slowdown? How Worrying Is The U.S. Slowdown? Chart 2U.S. Data Surprisingly Positive U.S. Data Surprisingly Positive U.S. Data Surprisingly Positive Chart 3Housing Market Should Stabilize Housing Market Should Stabilize Housing Market Should Stabilize In particular, the outlook for consumption looks healthy, with average hourly earnings growing at 3.3% YoY, consumer confidence close to an historic high, and the savings rate above 6%. Unsurprisingly, then, retail sales have boomed in recent months (Chart 4). Unless consumer confidence is dented by a repetition of the government shutdown or some other shock, consumption (68% of GDP, remember) should grow strongly this year. Add to this a residual positive impact of close to 0.5% of GDP coming from last year’s fiscal stimulus, and it is hard to imagine the U.S. going into recession over the next 12 months. Chart 4Consumption Booming Consumption Booming Consumption Booming The Fed will probably go on hold for now, however, given the market jitters in Q4. We are likely back to a situation like that in 2015-2016, where the Fed Policy Feedback Loop becomes the key factor for markets (Chart 5). When financial conditions tighten, with stock prices falling and the dollar appreciating, the Fed turns more dovish. However, this triggers a rally in risk assets and loosens financial conditions, allowing the Fed to start hiking again. With the tightening in financial conditions over the past six months, the Fed is likely to err on the side of caution for now (Chart 6). However, if our macro view is correct – and as inflation starts to pick up again after April, partly due to the base effect – the Fed will want to continue withdrawing accommodation over the course of this year. The Fed Funds Rate, at around 2.4% is still two hikes below what the FOMC sees as the neutral level of interest rates (the 2.8% terminal rate in the FOMC dots). We see the Fed, therefore, raising rates in June and perhaps hiking two or even three times this year. By contrast, the futures market assigns only a 25% probability of even one rate hike this year, and is even pricing in a small probability of a cut. Chart 5 Chart 6Tighter Conditions Mean More Cautious Fed Tighter Conditions Mean More Cautious Fed Tighter Conditions Mean More Cautious Fed Clearly, there are plenty of risks to the scenario of growth continuing. But those in the hands of President Trump, especially the trade war with China and the fight over funding of the wall on the border with Mexico, we don’t see as being serious impediments. Trump is fully aware that he is unlikely to be reelected in November 2020 if the U.S. is in recession by then. Every incumbent U.S. president since World War Two who fought for reelection during a recession failed to be reelected (Chart 7). The view of BCA’s geopolitical strategists, therefore, is that the White House and Congressional Democrats will agree to concessions to end the shutdown before the end of the current three-week stop-gap period. Less likely, Trump will declare a national emergency that will cause much controversy but have little impact on the economy. Our strategists also argue that there is a 45% probability of trade negotiations with China producing a result (at least a short-term one the president can boast about) before the March 1 deadline, and a further 25% probability of the deadline being extended without further sanctions being imposed.1 Chart 7Trump Won't Be Reelected In A Recession Trump Won't Be Reelected In A Recession Trump Won't Be Reelected In A Recession Equities: Analysts have become overly pessimistic about the earnings outlook for this year, cutting 2019 U.S. EPS growth to 7% (and only 2% YoY in Q1). Our top-down model (based on, admittedly optimistic, U.S. growth assumptions, but also headwinds from a stronger dollar) indicates 12% growth. If analysts are forced to revise up their numbers as better earnings come through, that should be a catalyst for further equity performance (Chart 8). We continue to prefer U.S. over European equities. The steady slowdown in European growth over the past 12 months has not yet bottomed, banks in Europe remain troubled, the earnings picture is less positive, and valuations relative to the U.S. are not especially attractive. We also remain underweight on EM equities: they may produce a positive return in a risk-on environment, but we see them underperforming DM as rising U.S. interest rates and a stronger USD put pressure on EM borrowers with excess foreign-currency debt. Chart 8Analysts Have Overdone Downward Revisions Analysts Have Overdone Downward Revisions Analysts Have Overdone Downward Revisions Fixed Income: The recent fall in U.S. Treasury yields was mainly caused by the inflation expectation component, itself very sensitive (if rather illogically so) to the oil price (Chart 9). As the oil price recovers (see below), inflation picks up moderately, and the Fed hikes by more than the market expects, we see the 10-year Treasury yield rising to 3.5% during the course of the year. BCA’s fixed-income strategists recently raised their recommendation on global credit to overweight, given more attractive spreads and the likelihood that the Fed will be on hold for the next six months.2 Their recommendation is for 3-6 months, and the Fed restarting the hiking cycle, say in June, might terminate the positive story. We are following their lead, by raising both high-yield and investment-grade bonds to overweight within the (underweight) fixed-income asset class. That means we are neutral credit in the overall portfolio. We would warn, though, that this is a somewhat short-term call: we still prefer equities as a way to play the continuing risk-on rally. Given the high level of U.S. corporate leverage, and the over-owned nature of the credit market, this is likely to be an asset class that performs very poorly in the next recession (Chart 10). Chart 9Inflation Expectations Should Recover Inflation Expectations Should Recover Inflation Expectations Should Recover Chart 10Corporate Leverage Is A Concern Corporate Leverage Is A Concern Corporate Leverage Is A Concern Currencies: Currencies will continue to be driven by relative monetary policy. With the growth desynchronization between the U.S. and other DMs set to continue (to a degree), we see modest further USD appreciation this year. The Fed (as argued above) will probably hike more than the market expects. But, given slow European growth, the ECB is unlikely to be able to hike in Q4 this year, as it currently is guiding for and the futures market implies (Chart 11). We see the ECB reopening the Targeted Long-Term Repo Facility (TLTRO), which expires soon. Italy and Spain have been big borrowers from this facility, and bank loan growth is likely to slow as it ends (Chart 12). A renewed TLRTO would be seen as a dovish move. Tighter dollar liquidity conditions also point to a stronger USD. U.S. credit growth continues to accelerate (to 12% YoY – Chart 13) in an environment where the monetary policy has tightened: credit growth is outpacing U.S. money supply growth by 7%. Historically this has been negative for global growth (mainly because the deteriorating liquidity is a problem for EM dollar borrowers) and positive for the dollar (Chart 14).3 Chart 11Can ECB Really Hike In 2019?

Which Will Tighten Liquidity Further ... Which Will Tighten Liquidity Further ... Which Will Tighten Liquidity Further Commodities: The supply/demand situation for oil should improve over coming months. With Saudi Arabia and Russia committed to cut supply by 1.2 million barrels/day, U.S. shale production growth slowing given the low one-year forward price for WTI, Canada reducing production, and Venezuela on the verge of collapse (which alone could remove 700-800k b/d from the market), our energy strategists see the crude oil balance in deficit over the next four quarters (Chart 15). Given this, they forecast Brent crude rebounding to above $80 a barrel. Other commodity prices are mostly driven by Chinese demand. We see China continuing to slow, until the accumulated effects of its fiscal and mild monetary stimulus start to come through in H2 and stabilize growth. Our analysis suggests that China remains very disciplined about the size and nature of its stimulus: it is not turning on the liquidity taps as it did in early 2016. Bank loan growth has stabilized, but shadow banking activity continues to contract, as the authorities persist with their crackdown and their emphasis on deleveraging (Chart 16). Industrial commodities prices are therefore likely to weaken over the next six months.  Chart 15Oil Balance In Deficit This Year Oil Balance In Deficit This Year Oil Balance In Deficit This Year Chart 16China Sticking To Credit Crackdown China Sticking To Credit Crackdown China Sticking To Credit Crackdown   Garry Evans, Senior Vice President Global Asset Allocation garry@bcaresearch.com   GAA Asset Allocation Footnotes 1      Please see Geopolitical Strategy Weekly Report, “So Donald Trump Cares About Stocks, Eh?”, dated 9 January 2019, available at gps.bcaresearch.com 2      Please see Global Fixed Income Strategy Weekly Report, “Enough With The Gloom: Upgrade Global Corporates On A Tactical Basis,” dated 15 January 2019, available at gfis.bcaresearch.com 3      For a detailed explanation, please see Foreign Exchange Strategy Weekly Report, “Global Liquidity Trends Support The Dollar, But…,” dated 25 January 2019, available at fes.bcaresearch.com

After rising for thousands of years, human intelligence has begun to decline in developed economies. This can be seen in falling IQ scores and a decline in math and science test scores. Environmental factors appear to account for the bulk of this decline, but no one knows what these factors are. If left unchecked, falling intelligence will severely undermine productivity growth. This could lead to lower equity multiples, larger budget deficits, and ultimately, much higher government bond yields. Technological advances, particularly in the genetic realm, promise to radically raise IQs. In a complete abandonment of its one-child policy, China will combine these controversial technologies with pro-natal measures in order to boost sagging birth rates. The coming Eugenic Wars will be one of the most important economic and geopolitical developments of the 21st century. Part 1: What The Tame Fox Says In 1959, a Soviet scientist named Dmitry Belyaev embarked on an ambitious experiment: to domesticate the silver fox. A geneticist by training, Belyaev wanted to replicate the process by which animals such as cats and dogs came to live side-by-side with humans. It was a risky endeavor. The Soviets had essentially banned the study of Mendelian genetics in favor of the blank slate ideology that is popular in progressive circles today. Belyaev persevered. Working under the guise of studying vulpine physiology, he selected foxes based on only one trait – tamability. Less than 10% of foxes made it to the subsequent generation, with the other 90% being sent off to fur farms. By the fourth generation, the changes were undeniable. Rather than fleeing humans, the foxes sought out their attention with no prompting whatsoever. They even wagged their tails and whined and whimpered like dogs do. The tame foxes also displayed physical changes. Their ears flopped over. Their snouts became shorter and their tails stood upright. "By intense selective breeding, we have compressed into a few decades an ancient process that originally unfolded over thousands of years," wrote Lyudmila Trut, who began as Belyaev’s assistant and took over the project when her boss died in 1985.  Genetically Capitalist? Evolution can broadly proceed in two ways. The first way is through random mutations. This form of evolution, which scientists sometimes refer to as genetic drift, can take thousands of years to yield any discernable changes. The second way is through natural selection, a process that exploits existing variations in genetic traits. As the Russian fox experiment illustrates, evolution driven by selective pressures (either natural or artificial) can occur fairly quickly. Did selective pressures manifest themselves in human evolution in the lead up to the Industrial Revolution? Did humans, in some sense, domesticate themselves? In his book, A Farewell To Alms, economic historian Gregory Clark argued in the affirmative. Clark documented that members of skilled professions in Medieval England had twice as many surviving children as unskilled workers (Chart II-1). Indeed, the fledgling middle class of the time had even more surviving children than the aristocracy, who were often out fighting wars. As a result, the wages of craftsmen declined by a third relative to laborers between 1200 and 1800, implying that the supply of skilled labor was growing more quickly than the demand for skilled workers over this period. Chart II-1Richer Men Had More Surviving Children In Medieval England The Most Important Trend In The World Has Reversed And Nobody Knows Why The Most Important Trend In The World Has Reversed And Nobody Knows Why In subsequent work, Clark and Neil Cummins argued that the spread of bourgeois values across pre-industrial England was more consistent with a model of genetic transmission than a cultural one (see Box II-1 for details). Similar developments occurred in other parts of the world. For example, in China, the gateway into the bureaucracy for a thousand years was the highly competitive imperial exam. Xi Song, Cameron Campbell, and James Lee showed that high-status men had more surviving children during the eighteenth- and nineteenth-centuries (Chart II-2).1 Chart II-2High-Status Men In China Produced More Descendants In The 18th And 19th Centuries The Most Important Trend In The World Has Reversed And Nobody Knows Why The Most Important Trend In The World Has Reversed And Nobody Knows Why The 10,000 Year Explosion Stephen Jay Gould famously said that “There’s been no biological change in humans in 40,000 or 50,000 years. Everything we call culture and civilization we’ve built with the same body and brain.” Gould was wrong. Data from the International HapMap Project show that human evolution accelerated by 100-fold starting around 10,000 years ago (Chart II-3). Chart II-3Human Evolution Has Accelerated 100-Fold Over The Past 10,000 Years The Most Important Trend In The World Has Reversed And Nobody Knows Why The Most Important Trend In The World Has Reversed And Nobody Knows Why In their book The 10,000 Year Explosion: How Civilization Accelerated Human Evolution, Gregory Cochran and the late Henry Harpending explained why evolution sped up so rapidly.2 The advent of agriculture led to a surge in population levels. This, in turn, increased the absolute number of potentially beneficial genetic mutations that could be subject to selection effects. Farming and the rise of city states also completely reshaped the environment in which people lived. Basic biology teaches us that environmental dislocations of this kind tend to generate selective pressures that cause evolution to accelerate. John Hawks, professor of anthropology and genetics at the University of Wisconsin-Madison, put it best: “We are more different genetically from people living 5,000 years ago than they were different from Neanderthals.” Many of the changes to our genomes relate to diet and diseases. The various genetic resistances that people have built up to malaria are all less than 10,000 years old. Mutations to the LCT gene, which confers lactose tolerance into adulthood, occurred independently in three different geographical locations: one in East Asia, one in the Middle East, and one in Africa. The Middle Eastern variant was probably responsible for the rapid enlargement of the Indo-European language group, which now stretches from India to Ireland. The African variant likely facilitated the Bantu expansion, which started near the present-day border of Nigeria and Cameroon, and then spread out across almost all of sub-Saharan Africa. Evolution Of The Human Brain About half of the genes in the human genome regulate some aspect of brain function. Given the rapid acceleration in evolution, it would be rather surprising if our own brains had not been affected. And indeed, there is plenty of evidence that they were. The frontal lobe of the brain has increased in size over the past 10,000 years. This is the part of the brain that regulates such things as language, memory, and long-term planning. Testosterone levels have also declined. That may explain the steady reduction in violent crime rates (Chart II-4). Chart II-4Long-Term Decline In Homicide Rates The Most Important Trend In The World Has Reversed And Nobody Knows Why The Most Important Trend In The World Has Reversed And Nobody Knows Why We know that certain genes that are associated with higher intelligence have been under recent selective pressure. For example, the gene that leads to torsion dystonia – a debilitating movement disorder – appears to have increased in frequency. Why would a gene that causes a known disease become more widespread? The answer is that individuals who have this particular mutation tend to have IQs that are around 10-to 20-points above the population average. Why IQ Matters IQ has a long and contentious history. Yet, despite numerous efforts to jettison the concept, it has endured for one simple reason: It has more predictive power than virtually anything else in the psychological realm. A simple 30-minute IQ test can help predict future educational attainment, job performance, income, health, criminality, and fertility choices (Table II-1 and Chart II-5). IQ even predicts trader performance!3 Table II-1What IQ Predicts (Results From Meta-Analyses) The Most Important Trend In The World Has Reversed And Nobody Knows Why The Most Important Trend In The World Has Reversed And Nobody Knows Why   Chart II-5IQ Tests Don’t Just Measure How Well You Can Do On An IQ Test The Most Important Trend In The World Has Reversed And Nobody Knows Why The Most Important Trend In The World Has Reversed And Nobody Knows Why Like most physiological traits, IQ is highly heritable.4 The genetic contribution to IQ increases from 20% in early childhood to as high as 80% by one’s late teens and remains at that level well into adulthood.5 This makes IQ almost as heritable as height (Chart II-6). Chart II-6The Inheritance You Cannot Renounce The Most Important Trend In The World Has Reversed And Nobody Knows Why The Most Important Trend In The World Has Reversed And Nobody Knows Why Although there is a great deal of variation among individuals, on average, more intelligent people earn higher incomes (Chart II-7). If the same relationship existed in the pre-industrial era, as seems likely, then human intelligence probably increased in a way that facilitated the economic explosion that we associate with the Industrial Revolution. The stunning implication is that the emergence of the modern era was a question of “when, not if.” Chart II-7IQ Tends To Be Positively Correlated With Income And Wealth The Most Important Trend In The World Has Reversed And Nobody Knows Why The Most Important Trend In The World Has Reversed And Nobody Knows Why Part 2: The Flynn Effect By the late-19th century, it had become clear that the rich were no longer having as many children as the poor. This realization, together with the growing popularity of Darwin’s theories, helped galvanize the eugenics movement. Contrary to popular belief, this movement was not a product of the far-right. In fact, the most vocal proponents of eugenics were among the progressive left. John Maynard Keynes, for example, served as the Director of the British Eugenics Society between 1937 and 1944. Yet, a funny thing happened on the road to idiocracy: The concerns of eugenicists did not come to pass. Rather than becoming dimmer, people became smarter. This phenomenon is now known as the Flynn Effect, named after James Flynn, a psychologist who was among the first to document it. Chart II-8 shows the evolution of IQ scores in a sample of countries between 1940 and 1990. The average country recorded IQ gains of three points per decade over this period, a remarkably large increase over such a relatively short period of time. Chart II-8The Flynn Effect: It Was Nice While It Lasted The Most Important Trend In The World Has Reversed And Nobody Knows Why The Most Important Trend In The World Has Reversed And Nobody Knows Why Explaining The Flynn Effect The Flynn Effect must have been entirely driven by environmental factors since genetic factors – namely the tendency of less-educated people to have more children, and to have them at an earlier age – would have reduced average IQs over the past two hundred years. But how could environmental factors have played the dominant role in light of the strong role of genes discussed above? The answer was proposed by geneticist Richard Lewontin in the 1970s. Lewontin suggested imagining a genetically-diverse sack of seed corn randomly distributed between two large identical fields. One field had fertilizer added to it while the other did not. Genetic variation would explain all of the differences in the height of corn stalks within each field, while environmental factors (the addition of fertilizer) would explain all of the difference in the average height of corn stalks between the two fields. This logic explains why genes can account for the bulk of the variation in IQs within any demographic group, while environmental effects may explain most of the variation across groups, as well as why average scores have changed over time. And what environmental effects are these? The truth is that no one really knows. Plenty of theories have been advanced, but so far there is still little consensus on the matter. Bigger, Healthier Brains It has long been known that learning increases the amount of grey matter in the brain. For example, a recent study showed that the hippocampi of London taxi drivers tend to be larger due to the need for drivers to memorize and navigate complex routes.6 The emergence of modern societies likely kicked off a virtuous circle where the need to solve increasingly complex tasks forced people to hone their learning skills, leading to higher IQs and further technological progress. The introduction of universal primary education amplified this virtuous circle. Better health undoubtedly helped as well. Early childhood diseases reduce IQ by diverting the body’s resources away from mental development towards fighting off infections. There is a strong correlation between measured IQ and disease burden across countries (Chart II-9). A number of studies have documented a strong relationship between the timing of malaria eradication in the U.S. and other parts of the world and subsequent observed gains in childhood IQs.7 Chart II-9IQ And Disease Burden The Most Important Trend In The World Has Reversed And Nobody Knows Why The Most Important Trend In The World Has Reversed And Nobody Knows Why Brain size and IQ are positively correlated. Forensic evidence from the U.S. suggests that the average volume of adult human skulls has increased by 7% since the late 1800s, or roughly the size of a tennis ball.8 Part 3: The End Of A 10,000 Year Trend The problem with environmental effects is that they eventually run into diminishing returns. This appears to have happened with the Flynn Effect. In fact, not only does the recent evidence suggest that the Flynn Effect has ended, but the data suggest that IQs are starting to decline. Chart II-10 shows that average math and science test scores fell in the OECD’s Program For International Scholastic Achievement (PISA) between 2009 and 2015, the latest year of the examination. The drop in math and science test scores has been mirrored in falling IQ scores. Flynn observed a decade ago that IQs of British teenagers were slipping.9 Similar results have been documented in France, the Netherlands, Germany, Denmark, and most recently, Norway. Chart II-10Math And Science Skills Are Slipping In The OECD The Most Important Trend In The World Has Reversed And Nobody Knows Why The Most Important Trend In The World Has Reversed And Nobody Knows Why The Norwegian results, published last year, are particularly noteworthy.10 Bernt Bratsberg and Ole Rogeberg examined three-decades worth of data on IQ tests of Norwegian military conscripts. Military duty has been mandatory for almost all men in Norway since 1814, which means that the study’s authors were able to collect comprehensive data on most Norwegian men and their fathers.  Their paper clearly shows that IQ peaked with the generation born in the mid-1970s and declined by about five points, or one-third of a standard deviation, for the one born in 1990 (Chart II-11). For the first time in recorded history, Norwegian kids today are not scoring as well as their parents. Chart II-11Norwegian IQs Have Been Falling For Those Born Since The Mid-1970s The Most Important Trend In The World Has Reversed And Nobody Knows Why The Most Important Trend In The World Has Reversed And Nobody Knows Why A Mystery What caused the sudden reversal of the Flynn Effect in Norway and most other developed economies? Nobody knows. We can, however, offer three possible theories: New Technologies For much of human history, rising intelligence and technological innovation were complementary processes, meaning that the smartest people were the ones who could best exploit the new technologies that were coming their way. Moreover, as noted above, even those who were less gifted benefited from the mental stimulation that a technologically advanced society provided. It remains to be seen how future technological advances such as generalized AI will affect human intelligence, but recent technological advances seem to have had a dumbing down effect.11 For example, the GPS has obviated the need for people to navigate unfamiliar locations, thus blunting the development of their visuospatial skills. Modern word processors have made spelling skills less important. Having all the information in the world just a click away is a wonderful thing, but it has reduced the need for our brains to retain and codify what we learn. Meanwhile, the constant bombardment of information to which we are subject has made it difficult to concentrate on anything for long. How many youth today can read a report of this length without checking their Facebook feed multiple times? My guess is not many. Diminishing Returns To Education The ability to take young bright minds, who would have otherwise spent their lives doing menial labor, and provide them with an education was probably the greatest tailwind to growth that the 20th century enjoyed. There is undoubtedly still scope to continue this process, but the low-hanging fruits have been picked. Educational attainment has slowed dramatically in most of the world (Chart II-12). Economist James Heckman estimates that U.S. high-school graduation rates, properly measured, peaked over 40 years ago.12 Chart II-12The Contribution To Economic Growth From Rising Human Capital Is Falling The Most Important Trend In The World Has Reversed And Nobody Knows Why The Most Important Trend In The World Has Reversed And Nobody Knows Why Despite billions of dollars spent, efforts to improve school performance have generally fallen flat. A recent high-level report by the U.S. Department of Education concluded that “The panel did not find any empirical studies that reached the rigor necessary to determine that specific turnaround practices produce significantly better academic outcomes.”13 This gets to a point that most parents already know, which is that when people talk about “bad schools," they are really talking about “bad students.” Deteriorating Health Better health probably contributed to the Flynn Effect. But is it possible to have too much of a good thing? More calories are welcome when people are starving, but today’s calorie-rich, nutrient-poor diets have led to a surge in obesity rates. A clean environment reduces the spread of germs, but it also makes children hypersensitive to foreign substances. Following German reunification, researchers observed that allergies were much more common among West German children than their Eastern peers, presumably because of the West’s more salubrious environment.14 All sorts of weird and concerning physiological changes are occurring. Sperm counts have fallen by nearly 60% since the early 1970s.15 Testosterone levels in young men are dropping. Among girls, the age of first menarche has declined by two years over the past century.16 Are chemical agents in the environment responsible? If they are, what impact are they having on cognitive development? Nobody knows. Reported mental illness is also on the rise. The share of U.S. teenagers with a reported major depressive episode over the prior year surged by over 60% between 2010 and 2017 (Chart II-13). The fraction of young adults that made suicide plans nearly doubled.17 More than 20% of U.S. women over the age of 40 are on antidepressants.18 Five percent of U.S. children are receiving ADHD medication.19 Chart II-13A Disturbing Deterioration In Mental Health The Most Important Trend In The World Has Reversed And Nobody Knows Why The Most Important Trend In The World Has Reversed And Nobody Knows Why Implications For Economic Growth And Asset Markets So far, the reversal of the Flynn Effect has been largely confined to the developed economies. Test scores are still rising in the developing world, albeit from fairly low levels. For example, two recent studies have documented significant IQ gains in Kenya and Brazil.20 In the poorest countries, opportunities for improving health abound. Even small steps such as fortifying salt with iodine (which costs about five cents per person per year) have been shown to boost IQ by nearly one standard deviation.21 Measures to reduce inbreeding are also likely to boost IQ scores.22 Yet, we should not underestimate the importance of falling cognitive skills in developed economies. Chart II-14 shows that there is a clear positive correlation between student score on math and science and per capita incomes. Chart II-14Positive Correlation Between Student Scores On Math And Science And Per Capita Income The Most Important Trend In The World Has Reversed And Nobody Knows Why The Most Important Trend In The World Has Reversed And Nobody Knows Why Most technological innovation still takes place in developed economies. There is an extremely tight relationship between visuospatial IQ and the likelihood of becoming an inventor (Chart II-15). Since IQ is distributed along a bell curve, a 0.1 standard deviation drop in IQs across the entire distribution will result in an 8% decline in the share of people with IQs over 100, a 14% decline in those with IQs over 115, and a 21% decline in those with an IQ over 130 (by convention, each standard deviation on an IQ test is worth 15 points). Chart II-15Having A Compass In Your Head Makes You A Better Inventor The Most Important Trend In The World Has Reversed And Nobody Knows Why The Most Important Trend In The World Has Reversed And Nobody Knows Why Falling IQs could result in slower productivity growth, which could further strain fiscal balances. Lower IQs are also associated with decreased future orientation.23 People who live for the moment tend to save less. A decline in savings would push up real rates, leading to less capital accumulation. History suggests that a deceleration in productivity growth and higher real rates will put downward pressure on equity multiples (Chart II-16). Chart II-16Equity Multiples Tend To Fall When Real Rates Rise And Productivity Growth Declines The Most Important Trend In The World Has Reversed And Nobody Knows Why The Most Important Trend In The World Has Reversed And Nobody Knows Why Part 4: Generation E For 200 years, the environmentally-driven Flynn Effect disguised the underlying genetically-driven decline in IQs that began not long after the dawn of the Industrial Revolution. Flynn has acknowledged this himself, noting at the 2017 International Society For Intelligence Research Conference that “I have no doubt that there has been some deterioration of genetic quality for intelligence since the late Victorian times.”24 Now that the Flynn Effect has reversed, both genes and the environment are working together to reduce cognitive abilities in developed economies. This means that the most important trend in the world – a trend that allowed the human population to increase during the Malthusian era and later allowed output-per-worker to soar following the Industrial Revolution – has broken down. Yet, there may be another twist in the story – one that began just a few months ago: the first members of Generation E were born. E Is For Edited ... Or Eugenics Lulu and Nana will be like most other children, but with one key difference: They will be the first humans ever to have their genomes edited through a procedure know as CRISPR-Cas9. Rogue Chinese scientist He Jiankui deactivated their CCR5 gene, which the HIV virus uses as a gateway into the body. His actions were rightfully condemned around the world for endangering the twins’ health by using a procedure that has not yet been fully vetted in animal studies, let alone in human trials (Lulu and Nana’s father is HIV+ but it is debatable whether the children were at an elevated risk of infection). He Jiankui remains under house arrest at the university where he worked. But whatever his fate, the dam has been broken. For better or for worse, the era of personal eugenics has arrived. The Return Of The Silver Fox It is easier to delete a gene than to add one. It is even more difficult to swap out a large number of genes in a way that achieves a predictable outcome. Thus, the successful manipulation of highly polygenic traits such as intelligence — traits that are linked to hundreds of different genes – may still be decades away.25 Predicting a trait is much simpler than modifying it, however. The cost of sequencing a human genome has fallen by more than 99% since 2001 (Chart II-17). Start-up company Genomic Prediction has already developed a test for fertilized embryos for IVF users that predicts height within a few centimetres and IQ with a correlation of 0.3-to-0.4, roughly as accurate as standardized tests such as the SAT or ACT.26 Other companies are following suit.27 Chart II-17Sequencing Costs Have Plummeted The Most Important Trend In The World Has Reversed And Nobody Knows Why The Most Important Trend In The World Has Reversed And Nobody Knows Why Some will recoil in horror at the prospect of selecting prospective children in this manner. They will argue that such technologies, beyond being simply immoral, will widen social inequality between those who can afford them and those who cannot. Others will counter that screening embryos for certain traits is not that dissimilar to what people already do with prospective romantic partners. They will also point out that mass usage of these technologies will drive down prices to the point that even poor people will be able to access them, thus giving low IQ parents the chance to have high IQ kids. They might also note that such technologies may be the only way to reverse the ongoing accumulation of deleterious mutations within the human germline that has been the unintended by-product of the proliferation of life-saving medicines.28 We will not wade into this thorny debate, other than to note that there will be huge incentives for people to avail themselves of these technologies. The Coming Eugenic Wars And not just individuals either – governments too. While the initial impact of eugenic technologies will be small, the effects will compound over time. Carl Shulman and Nick Bostrom estimate that genetic screening could boost average IQs by up to 65 points in five generations (Table II-2). Table II-2A Poisoned Chalice? Genetic Screening Can Raise IQ The Most Important Trend In The World Has Reversed And Nobody Knows Why The Most Important Trend In The World Has Reversed And Nobody Knows Why China has been investing heavily in genetic technologies. As Geoffrey Miller has argued, China’s infatuation with eugenics spans into the modern day.29 Like most other countries, fertility in China is negatively correlated with IQ. Mingrui Wang, John Fuerst, and Jianjun Ren estimate that China is currently losing nearly one-third of a point in generalized intelligence per decade, with the loss having accelerated rapidly between the 1960s and mid-1980s.30 The decline in the genetic component of Chinese IQs is coming at a time when the population itself is about to shrink. According to the UN’s baseline forecast, China will lose 450 million working-age people by the end of the century (Chart II-18). Meanwhile, the country is saddled with debt, the result of an economic model that has, for decades, recycled copious household savings into debt-financed fixed-investment spending in an effort to shore up domestic demand. Chart II-18China’s Labor Pool Is Shrinking The Most Important Trend In The World Has Reversed And Nobody Knows Why The Most Important Trend In The World Has Reversed And Nobody Knows Why The authorities may be tempted to tackle all three problems simultaneously by adopting generous pro-natal measures – call it the “at least one-child policy”– which increasingly harnesses emerging eugenic technologies. The resulting baby boom would strengthen domestic demand, thus making the economy less dependent on exports, while ensuring China’s long-term geopolitical viability. The Eugenic Wars are coming, and they will be unlike anything the world has seen before. BOX II-1 The Diffusion Of Bourgeois Values: Culture Or Genes? Higher-income people had more surviving children in the centuries leading up to the Industrial Revolution. Real per capita income was broadly stable during this period. This implies that there must have been downward social mobility, with sons, on average, being less wealthy than their fathers. This downward mobility, in turn, spread the characteristics of higher-income people across the broad swathe of society. What were these characteristics? Cultural values that emphasized thrift, diligence, and literacy were undoubtedly part of what was passed on to future generations. But surprisingly, it also appears that genetic transmission played an important, and perhaps pivotal, role. Models of genetic transmission make very concrete predictions about the correlations in economic status that one would expect to see among relatives. Biological brothers share 50% of their genes, as do fathers and sons. Likewise, first cousins share 25% of their genes, the same as grandfathers and sons. These facts yield two testable predictions: The first is that the correlation coefficient on status measures such as wealth, occupation, and education should be the same for relatives that share the same fraction of genes such as sibling pairs and father-son pairs. Box Chart II-1 shows that this is borne out by the data. The second prediction is that the correlation between status and genetic distance should follow a linear trend so that, for example, the correlation in wealth among brothers is twice that of first cousins and four times that of second cousins. Box Chart II-2 shows that this is also borne out by the data.

The correlation in measures such as wealth, education, and occupation is much higher among identical twins than fraternal twins. Adopted children turn out to be more similar to their biological parents on these measures when they reach adulthood than their adopted parents, even when the children have never met their biological parents. The parent-child correlation also remains the same regardless of family size, suggesting that spreading the same resources over more children may not harm life outcomes to any discernible degree, at least on the measures listed above.

There is no consensus on what causes it, but it probably reflects a number of factors: 1) It may take some children longer than normal to reach full intellectual maturity. Testing their IQs at a young age will result in scores that are lower than those expected based on their parents’ IQs. The opposite is true for children whose IQs increase relatively quickly in young age, but possibly top out earlier; 2) Environmental effects are probably more important in young age when a child’s brain is still quite malleable; 3) Self-reinforcing gene-environment interactions tend to increase with age. Children do not have much control over their environment, but as they get older, they will seek out activities that are more in keeping with their genetic predispositions. For example, a studious child may pursue a career that reinforces their love of learning. 9       "Cache Cab: Taxi Drivers' Brains Grow to Navigate London's Streets," Scientific American, (December 2011). 10       Atheendar Venkataramani, "Early Life Exposure to Malaria and Cognition in Adulthood: Evidence from Mexico," Journal of Health Economics 31:5, (July 2012): 767-780; Hoyt Bleakley, "Health, Human Capital and Development," Annual Review of Economics 2, (March 2010): 283-310; Hoyt Bleakley, "Malaria Eradication in the Americas: A Retrospective Analysis of Childhood Exposure," American Economic Journal: Applied Economics 2, (April 2010): 1-45. 11       "Anthropologists Find American Heads Are Getting Larger," ScienceDaily, (May 2012). 12       "British Teenagers Have Lower IQs Than Their Counterparts Did 30 Years Ago," The Telegraph, (February 2009). 13     Bernt Bratsberg and Ole Rogeberg, "Flynn Effect And Its Reversal Are Both Environmentally Caused," Proceedings of the National Academy of Sciences 115:26, (June 2018): 6674-6678. 14     On the face of it, artificial intelligence would appear to be a substitute for human intelligence. Many applications of AI would undoubtedly have this feature, especially those that allow computers to perform complex mental tasks that humans now must do. However, there are several ways that AI may eventually come to complement human intelligence. First, and most obviously, AI could be used to augment human capabilities either directly by hardwiring it into our brains, or indirectly through the development of drugs or genetic techniques which improve cognition. Second, looking further out, the benefits of highly intelligent AI systems would be limited if humans did not possess the requisite intelligence to understand certain concepts that are currently beyond our mental reach. No matter how well intentioned, trying to explain string theory to a mouse is not going to succeed. There are probably a multitude of ideas that AI could reveal that we simply cannot comprehend at current levels of human intelligence. 15     James Heckman and Paul La Fontaine, "The American High School Graduation Rate: Trends and Levels," The Review of Economics and Statistics 92:2, (May 2010): 244–262. 16     "Turning Around Chronically Low-Performing Schools," The Institute of Education Sciences (IES), (May 2008). 17     E. von Mutius, F.D.
