Special Report
Listen to a short summary of this report Executive Summary Sales & Profit Margins: The Two Propellers That Powered The Post-GFC US Rally US equity markets underperformed the global benchmark by 10% over 2000-08. Since then, the US has outperformed the global benchmark by about 170%. So, what has driven the US’ chartbusting performance in the post-GFC period? If we break down the US’ price performance into three parts – namely price-to-earnings ratio, net profit margins, and sales – then it becomes clear that growth in the latter two elements played a key role in driving US outperformance in the post-GFC era. Can the US’ outperformance relative to global markets persist going forward? It appears unlikely that the US’ high profit margins can sustain these levels of growth going forward. Distinct from the mean reversion argument, the US’ high profit margins are unusually concentrated amongst a fistful of firms. US firms may also find it challenging to maintain high sales growth as US GDP growth slows and given that America’s antitrust philosophy may soon undergo a once-in-a-generation change. Finally, it is worth noting that ‘sector composition’ effects played a significant role in driving US outperformance over 2008-22. Given that we expect outperforming sectors like Tech to become underperformers, this effect could become weaker going forward, thereby subverting another source of the US’ outperformance. Bottom Line: Forecasting is a tenuous science but given that the two prime propellers of the US’ performance engine are likely to confront headwinds going forward, investors should consider reducing allocations to US equities over a longer term, strategic horizon. Dear Client, I am meeting clients in Asia this week while also working on our Fourth Quarter Strategy Outlook, which will be published next week, followed by my webcast the week after. In lieu of our regular report this week, you are receiving a Special Report from my colleague, Ritika Mankar, discussing the sources of US equity outperformance over the past 14 years and the likely path ahead. Best Regards, Peter Berezin, Chief Global Strategist US Stock Market Dominance – It Wasn’t Always This Way Let us assume that you could travel back in time, and today was December 31, 2008. On this day you know that US and Japanese equity markets have underperformed the global benchmark (Chart 1). You also know that Europe (i.e., EU-27) has done marginally better than the US, while Emerging Markets (EM) have been the star outperformer. Let us further assume that by close of play today you have to deploy US$10bn across these four equity markets (across the US, Europe, Japan, and EM). As if the task of taking this decision on the last day of this historic year was not enough, let us assume that the funds you invest must be locked in until the fall of 2022. Finally, let us add one more condition to this task – let us suppose that you have no idea how markets would perform over the 2008-22 period, but you have perfect foresight about how the nominal GDP of these four regions would look like in 2022. Specifically, you know that EM GDP will have a terrific run between 2008 to 2022, US GDP will increase but by a far less impressive degree, European GDP will grow only slightly, and Japan’s GDP would be lesser in 2022 than it was in 2008 (Chart 2). Chart 1US Equities Underperformed The Global Benchmark By 10% Over 2000-08 Chart 2EM GDP Has More Than Doubled Since The GFC Chart 3US Equities Outperformed The Global Benchmark By About 170% Over 2008-22YTD If you were to take an investment decision based only this information, what is certain is that the fund you manage would underperform by a painful degree. This is because we now know that even though US markets had poor momentum in 2008, and the US’ GDP expansion paled relative to EM, US equity markets outperformed global markets by a wide margin since 2008 (Chart 3). On the other hand, despite positive momentum and high GDP growth, EM emerged as a distant second-best performer. Japan miraculously made it to third place despite a contraction in nominal GDP, and finally Europe ended up being the worst performer. If market momentum and GDP growth cannot explain these market movements, then what drove the US' outstanding performance in the post-GFC period? In this Special Report, we delve into answering this question in detail. The purpose of peeling the onion of the US' performance is simple – we hope to extract the insights that investors need to construct alpha-generating portfolios, in a world where forward time travel is not a possibility (yet). The US’ Performance Has Been Powered More By Earnings, Less By Valuations The two basic building blocks of any equity index are its earnings and its price-to-earnings ratio. The former captures the fundamentals backing an index, while the latter quantifies the valuation element. Breaking down the US’ performance into these two parts shows that earnings have been the prime factor that have propelled the rise of US equity markets in the post-GFC era (Chart 4). That earnings have been an important driver of the US’ outperformance becomes even more apparent when US earnings are compared to that of other major markets. For instance, the steep expansion in US earnings contrasts with the situation across the Atlantic. In Europe, earnings have trended lower relative to the global benchmark since 2008 and an increase in relative valuations has helped lend a floor to the index (Chart 5). The earnings report card for Japan and EM, on the other hand, have been surprisingly similar as earnings failed to rise meaningfully in both these geographies in the post-GFC period (Chart 6 and 7). Chart 4Earnings Have Played A Key Role In Propelling The Post-GFC US Rally Chart 5European Equities Supported More By Valuation Multiples Chart 6Earnings Growth Has Been Unimpressive In Japan Too Chart 7Earnings Have Trended Lower In EM Since 2008 In summary, the US' price-to-earnings ratio has had a meaningful role in driving US outperformance in the post-GFC period (Chart 8), but earnings expansion has played an outsized role (Chart 9). Chart 8Relative Valuation Multiples Have Played A Key Role In Supporting European Markets Chart 9Earnings Expansion In The US Has Been Phenomenal In fact, the growth in earnings in the US in the post-GFC era has been so noteworthy that if US equity market prices were to be broken down into its two building blocks i.e., earnings and price-to-earnings ratio, then the lion’s share of US equity market prices today would be attributed to its earnings (Chart 10). Expectedly, this contrasts with the situation in Europe where equity market prices have managed to stay afloat owing to a re-rating in its price-to-earnings ratio (Chart 11). These attribution analysis numbers are not meant to be taken literally, but rather, reflect the relative role played by earnings and price-to-earnings ratios in supporting the prices of regional indices. Chart 10US Equities: Supported More By Earnings Chart 11EU Equities: More Reliant On Multiples The Unsung Hero Behind The US’ Outperformance - Record Sales Expansion The index of a region can also be envisaged as the product of three elements, namely: (1) its price-to-earnings ratio; (2) its net profit margins; and (3) its sales. In other words: Price = (Price / Earnings) x (Earnings / Sales) x (Sales) While the US' healthy earnings tend to attract disproportionate investor attention, this formulation shows how a surge in US sales was the bigger driver of US outperformance (Chart 12). US profit margins experienced a sharp surge relative to global profit margins over the 2008-12 period, but then this parameter flatlined. US sales, on the other hand, have managed to register a steady march upwards over the entirety of the post-GFC period. The growth in sales of listed American corporations has in fact been so remarkable that a grand total of ten American firms now have annual sales of over $200 billion – which marks an all-time high for the US (Chart 13). Chart 12Post-GFC US Rally Powered By Record Sales Expansion Chart 13The US Is Home To Ten Firms With Revenues Of +$200bn Furthermore, the US’ lead on sales today is meaningful not only by its own historical standards, but by cross-country standards too. The rise in US sales has meant that the US is now home to half of the twenty largest listed corporations globally (Table 1). Conversely, Europe and Japan, despite being the third and fourth largest economies of the world, respectively, together account for only three names on this list. Notably however, Emerging Markets have managed to punch above their weight and are home to six of the top twenty firms by sales globally. Table 1The US Today Dominates The Global List Of Top 20 Firms By Revenue The steep rise in America’s sales in the post-GFC world is also unique because no other major market has experienced such a clear upward move in sales as the US has. Europe and Japan in fact saw their sales-per-share trend downwards in the post-GFC period (Chart 14 and Chart 15). Emerging markets were the only other major global market where sales-per-share managed to stay steady relative to the global benchmark (Chart 16). Chart 14Europe’s Sales Have Trended Lower Post-GFC Chart 15Japan’s Sales Also Trended Lower Post-GFC Finally, thanks to the high growth in US sales, the contribution of sales to US equity prices is far higher than the contribution of its net profit margins or its price-to-earnings ratio (Chart 17). This once again is in sharp contrast to a market like Europe, where only a smidgeon of the European equity prices pie can be attributed to its sales. Chart 16EM Sales Have Expanded Marginally Post-2008 Chart 17The Main Engine That Powers US Markets Is ‘Sales’ Chart 18US Profit Margins Have Also Been Expanding Steadily Post-GFC Distinct from the role played by growing sales, the US’ stellar post-GFC performance has also been powered by growing profit margins. It is notable that the US has experienced an unusually strong upward movement in its profit margins in the post-GFC period (Chart 18). Japan is the only other region which has seen its profit margins expand post-GFC, with both Europe and EM having experienced a fall in profit margins from the levels seen in 2008. A Quick Note On Dividends: The US Lags On Dividend Yields But Leads On Buybacks Thus far we have focused on the returns generated by the US market relative to the world and the factors that drove US outperformance since the GFC. If one were to focus on the dividend yield component, then it is notable that the US lags its peers on this front. Post-GFC, the first major cresting of dividend yields globally took place in 2009-10. Then the next major move down in yields took place in 2020 (Chart 19). While globally, yields have now recovered from this last dip, the US finds itself lagging on this metric which matters for pension funds that rely on annuities (Chart 20). Not only have dividend yields in the US almost halved since the GFC, but the gap between dividend yields offered by the US and other markets has widened over the last few years. Europe however has managed to stay the undisputed leader when it comes to dividend yields through most of the 21st century. Chart 19Global Dividend Yields Have Recovered From The Post-2020 Fall Chart 20US Lags Global Markets On Dividend Yields Chart 21Pace Of Buybacks In The US Has Been Meaningful Notably, however, while the US lags its peers on dividend yields, it leads when it comes to buybacks. The latter is evident from the fact that proxy measures of shares outstanding have trended lower in the US in the post-GFC period, as compared to the rest of the world (Chart 21). Finally, it is important to note that both the growth in dividends-per-share as well as the absolute level of dividends in the US has been high. This parameter has increased by 2.4 times since 2008 and US dividends in absolute terms are nearly 5 times that of Europe’s dividends today. The only reason why dividend yields have stayed low despite this is because US equity prices have had a stellar run in the post-GFC period. Can This Extent Of US Outperformance Persist? Having delved into the drivers of the US’ performance, we now know that a record expansion in sales and net profit margins have driven its outstanding performance in the post-GFC era. This in turn means that the probability of the US continuing to outperform over the next few years will be closely linked to its ability to maintain a lead on these two parameters. So how is the US positioned with respect to both these factors? The US’ High Profit Margins Appear Unsustainable, For A Wide Range Of Reasons We have established the fact that expanding profit margins have been a supporting driver of the US’ outperformance in the post-GFC period. Now, the consensus view is that US profit margins are extraordinarily high and that they will eventually come down to earth. The logic for this argument is often grounded in mean reversion. We have also previously highlighted that most of the increase in US profit margins has occurred due to rising margins within the tech sector and the accompanying increase in the market cap weight of tech within benchmark indices. Chart 22US High Profit Margins Are Concentrated Amongst Top Firms Aside from these reasons, two more factors could lead to the compression of US profit margins over the next few years. Firstly, it is worth noting that the US' high profit margins are unusually concentrated amongst a handful of firms. While the US as a market is characterized by high margins at the headline level, profit margins of companies below the top tier are notably lower than that of the top tier (Chart 22). If profit margins were uniformly high across the US listed space and the divergence was low, then the probability of sustaining elevated margins would have been higher. But given that the US uniquely suffers from a high profit margin concentration problem, the probability of the sustainability of US high profit margins appears lower. Secondly, history suggests that in the globalized world that we live in, any region’s profit margins fail to persist above the global average beyond a maximum of 15 years (Table 2). This makes sense and is in line with economic theory which suggests that when profitability in a particular market is excessive, then new firms will enter this space, increase competition, and thereby exert downward pressure on the incumbents’ profit margins. Table 2Regional Profit Margins Seldom Persist Above The Global Average Beyond 15 Years Given that US profit margins have now persisted above global levels for almost 13 years, if history were to repeat itself, then it appears highly likely that US profit margins would trend towards the global average over the next 2 years. US Sales Growth: A Peak Appears Nigh We now know that the rapid sales expansion experienced by US firms has been the prime driver of the US stock market outperformance since the GFC. However, the prognosis for this variable also appears shaky for the US. Chart 23US GDP And Sales Tend To Move In Lockstep The key macro variable which has the tightest theoretical link to the sales generated by the companies in a country is the country’s nominal GDP. Even as companies headquartered in the US end up selling to the global economy, history suggests that the link between the US’ nominal GDP and the sales generated by listed American firms are closely linked (Chart 23). Given that the pace of US nominal GDP growth is set to slow over the next few years (relative to both its past and relative to other major economies), US companies’ sales growth could end up slowing too (Chart 24). Also, given that the US revenue-to-nominal GDP ratio is already elevated, it is likely that even as the US’ nominal GDP keeps growing, the pace of conversion of this GDP into revenues will stay the same or may even diminish over the coming decade. Chart 24US GDP Growth Is Set To Slow Then from a bottom-up perspective, we are also of the view that the US economy’s ability to spawn mega-sized companies (by sales) may become increasingly compromised over the next decade. This is because a peculiar stagnation is in the works in the middle tier of American firms, which tend to become the mega-sized corporations of tomorrow. Finally, the US' antitrust philosophy is likely to undergo a once-in-a-generation change under the Biden administration. This could mean that America’s mega-scaled firms (which have had a free run up until now) could end-up baiting regulatory attention, restricting their ability to grow sales. US Price Performance: Strong Sector Effects Are Unlikely To Persist Chart 25Sector Composition Effect: Strongest For The US Lastly, it is worth noting that the price performance of the broad US equity index subverts the role played by “sector composition” in driving the US' outperformance. The fact that returns generated by the US benchmark are higher than the returns generated by a hypothetical US index which weights all sectors equally suggests that “sector composition” effects had a meaningful role in driving US outperformance. In fact, as compared to other major markets, the sector composition effect is the most prominent for the US (Chart 25). Another way of quantifying the role of sector effects is to compare the US’ market cap expansion relative to a global benchmark after removing the market cap of top-performing sectors. Expectedly, US outperformance relative to the global benchmark over the post-GFC period gets substantially reduced if the market cap of the three top-performing sectors (namely Information Technology, Consumer Discretionary, and Health Care) is adjusted for (Chart 26). To complicate matters, the sector composition effect in the US has been unwinding but remains high (Chart 27). Given that we expect outperforming sectors like Tech to turn into underperformers, the sector constitution effect in the US could weaken going forward, thereby subverting another source of US outperformance. Chart 26Extent Of US Outperformance Weakens Sans Tech, Consumer Discretionary, And Health Care Chart 27Sector Composition Effect In The US Remains High Investment Conclusions The prime drivers of US outperformance relative to the global benchmark in the post-GFC period have been ascendant sales and rising net profit margins. Forecasting is a tenuous science but given that both these propellers of the US equity market engine are set to face headwinds, investors should consider reducing allocations to US equities over a longer term, strategic horizon.
