Why are international stocks outperforming U.S. stocks: will this rotation continue?

Why Have International Stocks Outperformed U.S. Equities: Will This Rotation Continue?

The period of outperformance by international stocks relative to U.S. equities is once again entering the discussion framework of global institutional investors. Every few years, the market reassesses the allocation value of non-U.S. assets: first, valuation discounts attract capital; then inflows improve relative performance; then U.S. large-cap growth stocks regain dominance, and the rotation is again proven temporary. What is different this time is that the improvement in international stocks is backed not only by valuation repair, but also by more concrete macroeconomic and policy support, including a shift in European fiscal policy, corporate governance reform in Japan, temporary pressure on the U.S. dollar, and stronger global demand for diversified asset allocation.

For long-term investors, the real question is not “will international stocks definitely continue to outperform,” but rather: has this round of relative strength already evolved from a short-term valuation rebound into a more durable change in capital flows and the investment framework? If the answer leans yes, then what it affects is not just equity positioning, but the entire global markets asset allocation, portfolio diversification, and investment outlook.

Market Background

From a macro perspective, this improvement in international stock performance is occurring during a phase in which the global interest rate cycle and growth cycle are diverging again. Over the past few years, Federal Reserve rate hikes, a stronger dollar, and the dominance of U.S. mega-cap tech in return structures have led global capital to concentrate heavily in U.S. assets. At the same time, Europe has faced a longer period of low growth and low inflation, Japan has been slowly adjusting corporate governance and capital returns, and emerging markets have experienced greater volatility amid growth, policy, and external financing conditions.

Now, conditions are changing. According to the judgments of several international institutions in their 2026 market outlooks, international stocks had already shown improvement relative to U.S. equities in 2025, while relative valuations remained at a discount. For institutional investors, this combination of “already outperforming, yet still cheap” is usually more attractive than simple valuation recovery, because it suggests the market is not merely trading on expectations, but has already begun to validate earnings and policy changes.

In Europe, the role of fiscal policy deserves particular attention. After years of fiscal conservatism, Europe has begun to more actively direct public investment toward defense, infrastructure, and industrial resilience. For long-term capital allocation, this means corporate earnings may no longer depend solely on monetary easing or valuation expansion, but could receive more substantive demand support. Meanwhile, the European Central Bank’s relatively accommodative stance has also improved financial conditions. By contrast, although the U.S. economy remains resilient, market pricing of “American exceptionalism” is already very rich, and further upside requires stronger earnings re-acceleration to support it.

Current Capital Flows

From the perspective of capital flows, funds are tilting toward markets with stronger policy support, relatively cheaper valuations, and improving earnings expectations.From the perspective of capital flows, funds are tilting toward markets with stronger policy support, relatively cheaper valuations, and improving earnings expectations. European equities, select large Japanese companies, defense and infrastructure-related industrial chains, financials, and some non-U.S. assets benefiting from a temporary weakening of the dollar are once again attracting institutional attention.

Referring to the annual thematic frameworks of several institutions, a “multipolar world” is becoming one of the important narratives in global capital markets. Morgan Stanley has listed it as one of its key investment themes for 2026, while Goldman Sachs has also included “China’s resurgence” in its annual thematic outlook. This does not mean investors are betting on a full-scale recovery in a single region; rather, it shows that the market is increasingly accepting the view that future capital returns will no longer be monopolized by one economy, and that global portfolios need to place greater emphasis on regional diversification and thematic diversification.

Japan is also an important part of the changing capital flow. Over the past few years, the Tokyo Stock Exchange has pushed companies to improve capital efficiency, buyback policies, and shareholder returns, which has to some extent changed market behavior. For institutional investors, Japan is no longer just a market of “low valuations but hard-to-realize returns,” but is gradually becoming a sample market for improved corporate governance and higher capital returns. Even if the yen exchange rate is not the core variable in all investment decisions, governance reform itself is enough to support some long-term allocation demand.

In emerging markets, capital flows are becoming more selective rather than returning broadly. India continues to attract long-term capital attention because of its demographic structure, domestic demand expansion, and a relatively clear infrastructure investment path. But valuations are not cheap, meaning the market has already priced in a considerable amount of growth expectations. China is more complex: valuations in some technology and consumer assets have become more attractive, but geopolitical tensions, trade restrictions, and policy uncertainty still require more cautious position management. Overall, institutional investors are not simply buying the label “emerging markets,” but are carrying out a more refined screening across countries, sectors, and governance quality.

Investment Logic Analysis

Why is capital flowing back into international equities? The core reason is that multiple structural factors have begun to act in the same direction at the same time.

First, valuation gaps still exist. U.S. equities, especially large-cap technology and growth sectors, have long enjoyed a premium. By contrast, international equities in many markets still trade at a discount. For long-term investors, this discount does not in itself mean cheapness, but when valuation discounts appear alongside improving earnings and policy support, the risk-reward profile improves significantly.

Second, global growth momentum is becoming more dispersed. The United States remains the world’s most important capital market, but its advantages are increasingly concentrated in a handful of mega-cap stocks. Europe, Japan, and some emerging markets are, through policy, reform, and industrial adjustment, regaining capital’s attention. This diversification does not mean the U.S. is losing its core position; rather, it means the global investment landscape is becoming more multi-centered.Third, the impact of the U.S. dollar factor on international equity returns has reemerged. For investors denominated in U.S. dollars, a weaker dollar usually boosts the translated returns of non-U.S. assets. More importantly, the dollar is not just an exchange-rate variable; it is also an important signal of global liquidity and risk appetite. When the dollar moves out of a strong phase and into a more balanced range, non-U.S. assets are often more likely to attract allocation capital.

Fourth, institutional investors are rethinking concentration risk. Over the past few years, global portfolios have become increasingly concentrated in U.S. assets, especially U.S. technology stocks. As the interest-rate upcycle and market volatility have changed, pension funds, sovereign wealth funds, family offices, and large asset managers have all become more attentive to the long-term risks brought by excessive concentration in a single market and a single theme. This does not mean a wholesale exit from the United States; rather, it places greater emphasis on the necessity of portfolio diversification.

In this sense, the essence of international equity rotation is not “chasing lagging markets,” but a reallocation process driven jointly by macro cycles, policy changes, and capital rebalancing. For institutions that value a long-term investing strategy, such changes are often more important than short-term market sentiment.

Risk Factors

Although the relative environment for international equities has improved, whether this rotation can continue still faces multiple risks.

The most immediate risk comes from a renewed strengthening of the U.S. dollar. If the dollar rises significantly again, the aggregate returns of international equities for dollar-based investors could be dampened, and funds may flow back into U.S. assets. Historical experience shows that much of the improvement in the relative performance of international equities is ultimately partially offset by exchange-rate factors.

The second risk is whether Europe’s fiscal stimulus can truly translate into earnings growth. Markets may first trade the expectation, but if public investment fails to lift corporate revenues, profit margins, and capital expenditure, then valuation recovery may remain confined to the short term. A long-standing challenge for European markets has always been that “policy has the intent, but earnings must deliver.”

The third risk is that if U.S. corporate earnings accelerate again, the relative attractiveness of international equities will decline rapidly. The core support for U.S. stocks is not only valuation, but also earnings power, innovation capability, and the depth of global capital markets. If large U.S. technology and platform companies continue to sustain extremely high growth, international equities may improve in performance, but they still may not dominate in the competition for capital.

The fourth risk comes from geopolitical and policy uncertainty, especially in emerging markets and assets related to China’s industrial chains. When capital flows into these markets, investors often need to assess the regulatory environment, trade restrictions, sanctions risks, and supply chain security issues at the same time. For institutional investors, the risk is not whether to participate, but how to control exposure and scenario losses.

Long-Term OutlookFrom the perspective of the next 3–10 years, the long-term allocation value of international equities may be more worth discussing than it was over the past decade. The reason is not that any single market is certain to replace the United States, but that global capital markets are entering a more clearly multipolar phase. The divergence in macroeconomics, industrial policy, fiscal capacity, and geopolitical landscape means that sources of return will become more diversified, and portfolios will need to be more flexible.

If Europe can turn fiscal stimulus into more stable corporate earnings, if Japan’s corporate governance reforms continue to improve shareholder returns, and if some emerging markets can achieve higher-quality growth through domestic demand, infrastructure, and industrial upgrading, then international equities will no longer be merely a “low-valuation alternative,” but will gradually become part of core asset allocation.

For institutional investors, this means the key in the future is not to judge which market will “take all,” but to identify which regions and industries have more robust cash flows, governance structures, and policy support under the new macro framework. Pension funds care more about matching long-term liabilities, sovereign wealth funds care more about cross-cycle returns, family offices care more about wealth preservation and global diversification, and all of these needs point in the same direction: a more balanced global asset allocation.

However, long-term trends do not mean a linear rise. For international equities to truly form a sustained rotation, three conditions must work together: first, the U.S. dollar must not experience a prolonged, sharp strengthening; second, earnings improvement in non-U.S. markets must continue to be validated; and third, the relative advantage of U.S. assets must stop expanding further. As long as any one of these conditions reverses, the rotation may pause or even reverse.

Therefore, a more reasonable judgment is not whether “international equities will permanently replace U.S. stocks,” but that the weighting of international markets in global investment portfolios may be entering a more normal and more balanced revaluation phase. For long-term investors, the significance of this change is often greater than short-term gains and losses.

Conclusion

The improvement in the relative performance of international equities is worth attention not because it may represent a dramatic market reversal, but because it may reflect a change in the logic of global capital flows. Today’s market no longer revolves solely around the United States as a single center; instead, under the combined effects of the dollar, policy, valuation, governance, and geopolitical structure, it is evolving toward a more dispersed direction. For institutions seeking long-term investment returns, this means that the time to reassess the global asset allocation framework may already have arrived.
