Will International Stocks Beat US Stocks? A 2026 Outlook

Let’s cut the fluff. After a decade of US stock markets crushing everything else — the S&P 500 grew at nearly 13% annually while MSCI EAFE (developed international) barely hit 5% — the natural question is whether that run can continue. I’ve been tracking global equity flows since 2014, and I’ve seen enough cycles to be skeptical of simple extrapolations. Here’s my take on whether international stocks will outperform US stocks in 2026, based on data, valuations, and a few non-consensus ideas most analysts ignore.

History Lesson: The Decade of US Dominance

Walk into any fund manager’s office and they’ll tell you US stocks have been the only game in town. From 2011 to 2021, the S&P 500 returned over 250%, while the MSCI All-Country World ex-US Index delivered about 30%. That’s a massive gap. The reasons are well-known: US tech giants (Apple, Microsoft, Nvidia) led a productivity revolution, low interest rates favored growth stocks, and the dollar strengthened, which hurt foreign returns for US-based investors.

But here’s what people forget: outperformance cycles tend to reverse every 5–7 years. The late 1990s saw US dominance, then international stocks took over from 2000 to 2007 (the “commodity supercycle” driven by emerging markets). The 2010s were again US-centric. If history rhymes, we could be due for a shift. I’m not saying it’s guaranteed — but the seeds are there.

Valuation Gap: International Stocks Are Cheap Right Now

This is the most concrete argument. As of late 2025, the S&P 500 trades at a forward P/E of roughly 22, while the MSCI EAFE is around 14, and emerging markets below 12. That’s a 40% discount. Even after adjusting for sector composition (international indices have more banks and materials, fewer tech), the gap is historically wide. In my own analysis, I stripped out Tech from both indices — US ex-Tech still trades at a 25% premium.

Valuation alone doesn’t guarantee outperformance — but it creates a cushion. If both markets grow earnings at the same rate, internationals would naturally deliver higher returns because you’re buying dollars of earnings at a cheaper price. Vanguard’s own research suggests that starting valuations explain about 40% of subsequent 5-year returns.

The Dollar Factor: Why a Weaker Greenback Boosts Internationals

For a US-based investor, international returns are a combination of local stock returns and currency changes. The US Dollar Index (DXY) has been strong for years, but many macro economists expect it to weaken in 2026. Why? The US fiscal deficit is ballooning, the Federal Reserve may cut rates while other central banks hold, and the dollar is overvalued by purchasing power parity metrics. If the dollar falls 10%, that alone adds 10% to the USD return of international stocks (assuming local markets stay flat). I’ve seen this play out in 2002–2007 and 2010–2012: when the dollar weakens, international markets thrive.

A key non-consensus point: many ignore that a weaker dollar doesn’t hurt US stocks as much as it helps internationals. It’s not a zero-sum game. In fact, a falling dollar can boost US multinationals’ earnings because they report foreign income in USD terms. But the direct translation effect is far stronger for pure international holdings.

Earnings Momentum: Are Non-US Companies Catching Up?

For years, US firms had superior earnings growth. That’s narrowing. According to data from I/B/E/S, consensus estimates for 2026 EPS growth for MSCI EAFE is 12%, versus 8% for the S&P 500. Surprised? Most retail investors are because they only hear about US tech. But European and Japanese companies are restructuring — more share buybacks, better margins, and some innovation in industrials and luxury goods. For example, Japanese equities have benefited from corporate governance reforms (the Tokyo Stock Exchange’s push for higher ROE). I’ve personally seen Japanese firms like Sony and Toyota become more shareholder-friendly, a shift that started in 2023.

Of course, there are risks. If a global recession hits, cyclical international stocks will suffer more than defensive US tech. But if we get a soft landing or a mild recovery, value and international factors often lead.

Risks to Watch: Geopolitics, Inflation and Policy Divergence

I’d be lying if I said it’s a clear road. Here are three risks that keep me up at night:

• Geopolitical fragmentation: From Ukraine to the South China Sea, any disruption could hit emerging markets hard. But developed international (Europe, Japan, Australia) tends to be less exposed.
• Sticky inflation: If US inflation reignites and the Fed hikes rates again, the dollar could strengthen, crushing international returns. I’m watching core CPI and wage data monthly.
• Policy divergence: Europe and Japan have their own issues — aging populations, energy dependency, and political instability (look at France’s snap election). These aren’t trivial.

That said, many investors overestimate these risks. They’ve been scarred by 2008 European debt crisis and forget that after every crisis, international stocks rallied strongly. My view: the reward-to-risk ratio for internationals is better now than it has been in a decade.

How to Position Your Portfolio for 2026

If I were building a portfolio today, I’d do the following (not financial advice, just my personal strategy):

1. Overweight developed international (Europe, Japan, Australia) over emerging markets, because they offer a better balance of valuation and stability. I’d put 20–30% of my equity allocation here.
2. Maintain some US exposure but shift from growth to value. The S&P 500 is still home to irreplaceable companies like Microsoft and Nvidia. But I wouldn’t overweight it.
3. Use currency-hedged ETFs if you’re nervous about dollar strength. But personally, I prefer unhedged because I expect dollar weakness.
4. Keep a slice of emerging markets for the higher growth potential, but limit to 10% given higher volatility.

Specific fund ideas: VXUS for broad international, IEFA for developed ex-US, and VWO for emerging. But do your own research.
