When Japanese equities outperform U.S. markets on a dollar-adjusted basis, it triggers a "geographic diversification trade." This attracts a new wave of foreign investors, particularly from the U.S., whose capital inflows then push Japanese stock prices and multiples even higher, creating a positive feedback loop.

In 2025, US stocks underperformed global peers despite superior earnings growth. Non-US markets saw significant price increases on flat or negative earnings, a divergence that Goldman Sachs Wealth Management believes is unsustainable, reinforcing their long-term US overweight thesis based on earnings fundamentals.

Contrary to the dominant narrative of US market leadership, European equities have actually outperformed their US counterparts when measured in constant currency terms since the last US presidential election. This surprising trend is a fact that most investors may not realize.

While stock markets appear to be reaching all-time highs in dollar terms, this is an illusion created by currency devaluation. When the S&P 500's value is measured in a stable asset like gold, it has actually declined since the pre-COVID era. This reveals that gains are not from value creation but from a weaker dollar.

The US is no longer the undisputed best option but simply the least bad one. This decline is evidenced by the shrinking role of the dollar in global trade and savvy investors like Warren Buffett diversifying away from the US, signaling a need for individuals to rethink their own financial strategies.

While US equities have traditionally been a bellwether for global sentiment, a significant rotation is underway. Stagnant US tech stocks are being overshadowed by strong performance elsewhere, with European equities up 6% and Emerging Market equities up 13%. This suggests capital is flowing into other markets, reducing EM's dependence on US performance.

The classic "stocks down, dollar up" correlation is weakening. A J.P. Morgan model shows that relative US equity underperformance (dollar-negative) is currently offsetting the effect of an outright global equity decline (dollar-positive). This dynamic leads to only modest moves in the dollar despite stock market stress.

While the S&P 500's 19% gain since last year seems strong, it significantly lags global performance. An ETF tracking worldwide stock markets is up 42% in the same period, with markets like South Korea and the Eurozone showing even larger returns. This indicates a potential "sell America" trend among global investors.

Contrary to popular belief, when measured in constant currency, European equities have outperformed their US counterparts since the last US elections. This trend is not widely recognized by investors, setting the stage for a potential re-evaluation of the region.
