American Unexceptionalism

Executive Summary

Investors today take for granted that the S&P 500 is an inherently superior group of stocks to those outside of the U.S. This belief stems not merely from better returns from the S&P 500 over the past 15 years, but also from superior fundamental growth for the S&P 500 relative to other stock indices. Investors consequently pay significantly higher multiples for U.S. large caps than they do for other stocks. But the superior fundamental performance of the S&P 500 is entirely due to mega-cap technology stocks. The rest of the S&P 500 has not shown particularly impressive fundamental performance but is still accorded a premium multiple. With the U.S. economy facing a unique and difficult set of negative supply shocks today, it seems unlikely that the average company in the S&P 500 will somehow start to prove exceptional from here. Even the “Magnificent Six” may struggle to justify their currently lofty valuations, although in their case, a continuation of their historical growth rates would suffice to do so. The rest of the world benefits from much lower valuations, growth on par with the U.S., a more tractable set of economic challenges, and the tailwind of a very overvalued U.S. dollar. We believe investors who are substantially overweight U.S. large cap stocks would be well advised to rethink their stance.

Introduction

Most investors believe that the U.S. economy is superior to the rest of the world and that the S&P 500 is better than all other groups of stocks. 1 The common wisdom is that if you invest in U.S. equities “for the long term,” you’ll compound capital at somewhere between 9% and 12%. Going outside the U.S., by contrast, is generally seen as needlessly risky: returns in the rest of the world have been somewhere between awful (China) and uninspiring (Europe) since the GFC, and it is a fact that no economy today can boast of the resilience we have seen in post-pandemic America.

The reason people are bulled up on the U.S. stock market is therefore quite straightforward: the U.S. has had a rip-roaring economy, and domestic equities have massively outperformed every other broad stock or bond index for over a decade. The S&P 500, for instance, has outpaced the rest of developed market equities 2 by a cumulative 150% in the past fifteen years. To state the obvious: that’s a lot. And those of us (and we really do mean us) who have been systematically underweight the U.S. for those fifteen years should readily admit ex-post that this was a mistake.
