Something genuinely unusual happened in 2025 in the world stock market. The United States underperformed major international markets for the first time in nearly 15 years.
Europe, China, and Asia generated almost double the total returns of the S&P 500 in dollar terms. Investors who kept their money entirely in US equities — a reasonable habit after years of American outperformance — left serious gains behind. That shift didn’t happen randomly. It reflects structural changes that haven’t fully played out yet.
Understanding what drove that divergence is the most important thing any globally-aware investor can do heading into the rest of 2026.
Why the US Lost Its Automatic Edge
For most of the last decade, US large-cap tech carried the world stock market on its back. The concentration was extreme and the returns justified ignoring it.
In 2025, that changed. The gap in growth-adjusted valuations between US equities and the rest of the world narrowed sharply. US stocks drove their gains almost entirely through earnings growth — particularly in large technology companies. Elsewhere, markets benefited from both improving earnings and rising valuations. That second driver gave international markets an extra source of return that the already-expensive US market couldn’t replicate.
Goldman Sachs Research currently forecasts 11% global equity returns over the next 12 months including dividends. They see earnings and economic growth across multiple regions — not just the US — providing the support. The broad global bull market likely continues, but 2025’s dramatic advance probably won’t repeat.
The caveat worth taking seriously: valuations have risen to historically elevated levels across all regions. Not just the US. Japan, Europe, and emerging markets all look stretched relative to historical norms. That compresses the margin for error everywhere.
Germany and Europe Changed the Calculus
For years, European markets traded at persistent discounts to the US on the assumption that growth would remain sluggish and fiscal policy would stay constrained.
Germany broke that assumption. The country launched a massive fiscal stimulus programme — a structural shift, not a temporary measure — and markets reacted. German equities ran hard. European defence stocks surged as governments across the continent accelerated spending under the Europe 2030 defence roadmap. Fiscal expansion in the eurozone, long impossible under old budget rules, suddenly became real policy.
J.P. Morgan Research specifically flagged eurozone fiscal stimulus as likely to become significantly more impactful through 2026. Charles Schwab noted German reforms as a concrete reason international stocks carry genuine upside this year. These aren’t vague optimistic projections — they point to specific policy decisions already in motion.
The risk sitting alongside this opportunity is currency. Unhedged investors in European assets face real currency volatility. The euro’s strength has already cut into overseas bond returns for Swiss and eurozone-based investors holding dollar and yen-denominated debt. Anyone building a global equity position needs to decide consciously whether to hedge currency exposure or accept it as part of the trade.
China’s Green Shoots and Why They Matter for India Too
China represents roughly 30% of the MSCI Emerging Markets Index. When China moves, the entire EM complex feels it.
After a multi-year private sector slowdown, analysts at J.P. Morgan and Charles Schwab both identify potential green shoots of consumer recovery in China through 2026. China also carries an advantage in AI infrastructure that Western markets often overlook — plentiful low-cost electricity compared to the supply-constrained and expensive energy environment in the US. That edge could sustain AI investment momentum in Chinese tech even if US AI capex growth slows.
For India specifically, the picture is more complicated. Indian equities saw record foreign institutional investor sell-offs through 2025. The rupee weakened against the dollar — analysts estimate it could approach 92 per dollar without RBI intervention — and that rupee trajectory directly affects the USD-denominated returns that drive FII decisions. Any further rupee weakness accelerates outflows. A reversal in FII flows is the single most anticipated trigger for Indian market recovery, and it hasn’t arrived cleanly yet.
The 2026 story for Indian equities is a stock-picker’s market more than an index-level rally. Earnings delivery, the Union Budget execution, and trade deal progress will separate individual names from the broad index.
Japan Keeps Getting Overlooked
Japanese equities ran in 2025 and the story behind that run hasn’t ended.
Corporate governance reforms pushed companies to return more capital to shareholders through buybacks and dividends. Return on equity at major Japanese companies climbed meaningfully — a metric that had lagged global peers for decades. Governance reforms in Korea followed a similar pattern for different structural reasons.
Both markets carry something that expensive US and European markets currently lack: genuine valuation support combined with improving shareholder-friendly behaviour. That combination attracts long-term institutional capital steadily rather than hot money chasing momentum.
What a Sensible World Stock Market Allocation Looks Like Right Now
Running all of your equity exposure in one country — any country — looks far riskier in 2026 than it did in 2022.
Geographic diversification delivered measurable results in 2025 for the first time in years. The same principle that drives diversification across asset classes — don’t let every position respond to the same shock at the same time — applies across regions too. US tech sells off hard on rate fears. European industrials don’t move the same way. Japanese exporters don’t respond the same way either. That separation is the value.
Chasing whatever ran hardest last year is the wrong starting point. The world stock market in 2026 rewards investors who look at where earnings growth is accelerating, where valuations still offer room, and where policy changes create structural tailwinds — not just who had the best chart.
Europe and Japan fit that description better than they have in a long time.
