Why International Investors Could Outperform U.S.-Only Investors in 2026

Here are three key reasons why international investors could have a field day, while investors who stay invested only in U.S. stocks could underperform.

Key Points
  • As U.S. stocks reach high valuations, international markets, especially in Canada, Europe, and parts of Asia, offer compelling opportunities with attractive valuations, suggesting potential outperformance in 2026.
  • Cooling inflation and favorable currency dynamics provide additional tailwinds for international investments, while diversification remains crucial amid geopolitical risks and market cycles.

For more than a decade, U.S. investors have seemed unstoppable. The tech-heavy S&P 500 has dramatically outpaced most global indices, minting fortunes for anyone disciplined enough to stay invested. But as 2026 unfolds, international investors may find themselves in a unique position to catch (or even outperform) their U.S.-focused counterparts.

For those looking to create a robust portfolio that can withstand potential headwinds on the horizon, but also see impressive upside in a bull market environment, I think Canadian stocks are a great place to look. Here’s why.

Valuations matter

The setup is as much about math as it is psychology. After years of market dominance, U.S. stocks are now priced for perfection. The “Magnificent Seven” continue to trade at lofty multiples, and even quality mid-caps look expensive relative to global peers. Meanwhile, in international markets (particularly in Canada, Europe and parts of Asia), investors have plenty of opportunities with attractive valuations that haven’t been this compelling in years.

This valuation gap could prove powerful. The MSCI EAFE Index, which tracks developed markets outside North America, trades at roughly 14 times forward earnings. The S&P 500? Closer to 21. When investors pay 50% more for the same dollar of earnings, future returns often disappoint. History has shown that valuation mean reversion tends to favour cheaper markets, especially when combined with improving economic momentum.

Inflation readings matter, as do interest rates

There’s evidence that such momentum is building. Europe’s inflation has cooled faster than in the U.S., giving the European Central Bank room to cut rates sooner. Meanwhile, Japan’s corporate reforms and wage growth trends have reignited investor interest after decades of stagnation. Emerging markets, from India to Brazil, are also benefiting from stronger domestic demand and improving governance.

Currency dynamics could add another tailwind. The U.S. dollar appears to be coming off its highs after years of strength. A softer dollar typically boosts returns for non-U.S. assets when translated back to greenbacks. For globally diversified investors, that’s a quiet advantage that can compound meaningfully over time.

Of course, there are risks

Now, diversification isn’t a guarantee. Geopolitical risks, uneven growth, and currency volatility all remain part of the international investing playbook. But viewed through a long-term lens, spreading capital beyond U.S. borders looks more like smart positioning than blind optimism.

It’s worth remembering that global leadership rotates. The U.S. took the torch from emerging markets in the 2010s, just as emerging markets outpaced the U.S. in the 2000s. Investors who recognize the rhythm of these cycles (and act on them early) tend to capture the best opportunities.

In 2026, that rhythm may once again be changing. For investors willing to broaden their horizons, patient international exposure could turn into one of the year’s more rewarding calls.
