Key Takeaways
- • International stocks outperformed U.S. equities by approximately 14 percentage points in 2025, with momentum continuing into H1 2026, driven by weaker dollar, American tariff policies, and aggressive interest rate cuts in non-U.S. markets.
- • Non-U.S. equities have significantly lower technology sector exposure than U.S. benchmarks, positioning them to benefit from AI investment spillover into second-order industries including computer hardware, power delivery, and basic materials.
- • Mega-cap U.S. tech stocks ("Mag-7") have underperformed in H1 2026 due to investor concerns over elevated AI capital expenditure requirements, creating a rotation dynamic that favors international diversification.
- • According to J.P. Morgan research, stocks excluding the United States outperformed U.S. stocks by 25 percentage points during the measured period, with non-U.S. equities remaining valued at a discount to U.S. benchmarks despite their outperformance.
- • Strategic government investments in self-sufficiency across developed and emerging markets have created opportunities in industrials, materials, and financials sectors, with European banks emerging from debt crises offering attractive valuations alongside innovation hubs in China and emerging markets.
Summary
International equity markets have demonstrated unusual strength in the first half of 2026, reversing more than a decade of U.S. market dominance driven by technology mega-caps. According to Fidelity's midyear outlook, international stocks outperformed U.S. equities by approximately 14 percentage points in 2025, with this momentum accelerating into 2026. J.P. Morgan research indicates even more dramatic divergence, with non-U.S. stocks outperforming U.S. equities by 25 percentage points during the period. This shift reflects a combination of macroeconomic factors, including American tariff policies, dollar weakness, and more aggressive interest rate cuts implemented across developed and emerging markets outside the United States.
The performance divergence has been substantially influenced by shifts in investor positioning around artificial intelligence investments. While AI demand initially concentrated in U.S. mega-cap technology stocks, the market has begun rotating away from these positions amid concerns over sky-high AI capital expenditure requirements. Bloomberg reporting indicates that the rotation out of mega-cap tech has become a defining theme of Q2 2026, with investors reassessing valuations and risk-reward dynamics. This rotation has simultaneously created opportunities in international markets, where lower technology sector exposure has positioned equities to benefit from second-order AI spillover effects.
AI investment is now spilling into industries beyond core semiconductor and software companies. Memory and storage vendors, computer hardware manufacturers, power delivery infrastructure, and basic materials suppliers are experiencing elevated demand as companies build out AI infrastructure globally. This broader investment pattern has benefited international markets, where industrial conglomerates, materials producers, and infrastructure-related companies carry greater portfolio weight than in U.S. benchmarks. Additionally, strategic government investments across developed and emerging markets aimed at increasing economic self-sufficiency have supported industrials, materials, and financial sectors—areas where non-U.S. markets maintain significant exposure.
European financial institutions represent a particularly compelling opportunity set within international markets. After an extended debt crisis, European banks have substantially deleveraged and now trade at valuations substantially below historical averages and their U.S. counterparts. Fidelity managers have identified these institutions as candidates for revaluation as economic conditions stabilize. Emerging markets, particularly in China and other developing economies, are simultaneously evolving into innovation hubs that extend AI adoption beyond traditional technology clusters, creating diversified growth avenues outside established U.S. technology centers.
Despite strong H1 2026 performance, non-U.S. equities remain valued at a discount to U.S. stocks in absolute terms, suggesting continued structural opportunity for investors seeking geographic diversification. The combination of valuation support, government investment tailwinds, and exposure to second-order AI benefits creates multiple return drivers that could sustain international outperformance beyond the current period.
