Market Perceptions Shift as American Exceptionalism Wanes

The sense of American exceptionalism in the stock market is starting to feel, well, a bit strange. Just a year ago, talks among investors revolved around how US stocks seemed like a sure bet, poised to dominate the global scene, especially with the influence of new and promising leadership aimed at driving growth.

Now, five months later, that narrative has taken a nosedive. The S&P 500, the primary US stock index, showed some recovery after a tumultuous dip in April, particularly driven by retail investors. However, Europe has outpaced the US, with countries like Italy and Germany seeing impressive gains of around 20%, and other nations, like Poland, even more. Interestingly, global funds that don’t include US stocks are gaining traction.

Coming to terms with the idea that America’s time of market dominance might be over is, well, a tricky realization. Matt Gibson from Goldman Sachs Asset Management notes the surge in questions he’s fielding about whether the US markets have peaked. It’s something on everyone’s mind; some investors are starting to act on these thoughts.

“Acting” can mean various strategies. Some are putting hedges in place to safeguard against potential downturns in US stocks. Others are looking to shield themselves from a weakening dollar, which could further impact their investments. Many I’ve spoken with recently are contemplating reducing their US stock exposure, at least for the foreseeable future.

This approach seems sensible when it comes to risk management. Still, it prompts a deeper reflection on how we reached this point. A recent paper by Antti Ilmanen and Thomas Maloney of the hedge fund AQR suggests that the notion of American exceptionalism has been overly relied upon. Investors have come to view it almost as an unshakeable truth, and those urging a more global investment approach have often been dismissed.

Some analysts are even using the term “bubble” in this context. Ilmanen, while cautious, points out that much of the US’s outperformance was due to shifts in valuation rather than purely growth factors. There’s a sentiment of uncertainty; he mentions that he doesn’t believe this trend will remain constant indefinitely.

The US market had a head start in growth compared to the rest of the world during the 1990s and maintained that momentum into the early 2020s. The narratives surrounding these prosperous times focused on America’s unique entrepreneurial spirit and robust market structures, alongside expectations for continued strong economic growth. While revenue figures in the US were impressive, the valuations themselves were even more staggering, driven partly by the phenomenon of investors gravitating toward well-performing stocks and a strong dollar enhancing that experience.

This dynamic fostered an unparalleled market power that significantly uplifted US valuations compared to European stocks by the end of last year. In the late 1980s, US valuations stood at half those abroad, but by last year, they were nearly double. AQR’s paper raises an important point: should investors be concerned about these historically high US valuations in 2025? Absolutely. Ilmanen argues that there’s been a misinterpretation of increased stock prices which may not be justified by fundamental growth.

What we’re seeing now in market performances might be just a blip, but downplaying these risks feels both comfortable and somewhat arrogant. It’s not just domestic political dynamics, shaping the economic landscape, but also the competitive challenge posed by China, particularly in artificial intelligence, adds another layer to the complexities we’re facing. The protective barriers around the US market aren’t as daunting as once imagined; they’re perhaps just not as deep as we thought.

Ultimately, how individuals interpret this evidence hinges on their recent experiences versus long-held narratives. While the success stories have thrived over the years, the recent surge in scrutiny from fund managers hints that the era of American market dominance may be drawing to a close.
