Fidelity says your portfolio may be 'too American'

If your entire portfolio lives in the S&P 500, Fidelity has a message for you: The rest of the world is pulling ahead, and you’re sitting on the sidelines.

Fidelity’s latest ETF screen shows the MSCI World (ex U.S.) up about 8% year to date in 2026. The S&P 500 has lagged that pace overall, even after a recent bump tied to the market’s reaction to the Block layoffs.

That performance gap follows international stocks topping U.S. stocks in 2025 for the first meaningful stretch in nearly two decades.

The MSCI World (ex U.S.) Index delivered a 32.7% total return last year, compared with 17.9% for the S&P 500, according to FactSet data cited by First Trust.

International equities posted their best calendar-year performance since 2009, driven by attractive valuations, a weakening U.S. dollar, and expansionary fiscal policies across Europe and Asia. And the tailwinds are far from spent.

Here’s what’s fueling the global rally, which international ETFs Fidelity is flagging. And most importantly, here’s what it means for your money.

Why Fidelity is waving a red flag at U.S.-only portfolios

American investors have become dangerously lopsided. After more than a decade of U.S. outperformance, U.S. stocks have grown from about 30% of the MSCI World Index in the 1990s to roughly 75% today, leaving many portfolios heavily exposed to a single country’s market.

Fidelity’s Capital Markets Strategy Group recently pointed out that earnings growth has strengthened across all major global regions.

Historically, that pattern has favored non-U.S. stocks, especially when paired with a softer dollar and easing financial conditions abroad, which is exactly the setup investors are seeing in early 2026.

The valuation gap amplifies the argument: The S&P 500 trades at a trailing price-to-earnings ratio near 30x, more than double its long-term average, while the MSCI ACWI ex-USA sits around 20.6x, according to InvestmentMarkets.

The S&P 500’s dividend yield of 1.17% also trails the 1.6% offered by ex-U.S. markets.

When U.S. stocks command nearly double the earnings multiple of international peers but no longer enjoy materially faster earnings growth, that premium becomes harder to justify.

The IMF’s January 2026 World Economic Outlook projects global GDP growth of 3.3% this year, outpacing the U.S. at 2.4%, according to First Trust Portfolios.

When the world’s economy is growing faster than America’s, the earnings potential for companies based outside the U.S. tends to expand.

Three international ETF themes Fidelity is watching right now

Fidelity’s latest ETF screener research highlights three distinct regional themes: Europe, Japan, and Latin America. Each has its own catalyst and its own risk profile.

When I dug into the three screens, what stood out was not just the fund names, but also the differences in exposure levels between ETFs that look similar on the surface.

Europe: Defense spending is rewriting the playbook

Europe isn’t just tagging along in the global rally. Several European countries, including Greece, Poland, and Spain, ranked among the world’s best-performing stock markets in 2025, according to FactSet.

The biggest catalyst: NATO allies have committed to raising defense expenditures to 3.5% of GDP by 2035, according to Janus Henderson. Germany earmarked roughly €108 billion for defense in its 2026 budget, a 25% year-over-year increase, and the STOXX Europe Aerospace & Defense Index surged more than 65% in 2025, per Datasite.

Fidelity’s Europe-focused ETF screen surfaces five funds to research further: iShares Core FTSE 100 UCITS ETF, Franklin FTSE United Kingdom ETF, Global X DAX Germany ETF, Franklin FTSE Switzerland ETF, and Franklin FTSE Germany ETF.

Most are single-country bets, so if you’re not comfortable picking one economy, a broad developed-market international ETF captures the European rally without the concentration risk.

Japan: Corporate governance reforms keep delivering

Japanese corporations have been overhauling governance standards, returning more capital to shareholders, and improving returns on equity, according to Fidelity.

Fidelity’s Japan screen (at least 30% Japanese stock exposure, expense ratios of 0.38% or below) highlights the following.

• Avantis International Small Cap Value ETF (AVDV)
• JPMorgan Betabuilders Japan ETF (BBJP)
• Vanguard FTSE Pacific Index Fund ETF Shares
• iShares Edge MSCI International Value Factor ETF
• Franklin FTSE Japan ETF

The exposure range matters enormously here, and this is where I think many investors get tripped up.

AVDV offers just 32% Japanese exposure alongside holdings from other international markets, while BBJP is a pure-play 100% Japan bet.

Two ETFs that appear in the same screener result can give you radically different portfolios. Before buying, check the fund’s country breakdown, not just its name.

Latin America: a commodity boom with staying power

The commodity supercycle is one of the most powerful structural trends supporting Latin American equities.

Several of the world’s largest miners operate from South America, sitting on vast reserves of gold, silver, copper, lithium, and other critical minerals. Fidelity noted that this commodity leverage, combined with central bank easing and improving macro stability, has supported earnings growth and attracted global capital.

Fidelity’s LatAm screen (at least 50% exposure, expense ratios of 0.81% or below) flags iShares MSCI Brazil ETF (EWZ), iShares Latin America 40 ETF (ILF), iShares MSCI Mexico ETF (EWW), iShares MSCI Chile ETF (ECH), and Franklin FTSE Brazil ETF (FLBR).

That list is heavily tilted toward Brazil, with Mexico and Chile as the other main country exposures.

Latin American markets carry significantly more political and currency risk than developed-market peers.

Brazil’s fiscal policy trajectory and Mexico’s trade relationship with the U.S. are both live variables that can whipsaw returns. For most investors, I would suggest treating LatAm as a smaller satellite allocation rather than a core international holding.

What this means for your wallet, and what to do now

The S&P 500 remains home to some of the world’s most profitable companies, and 2026 earnings growth expectations are still around 13%. The point is that an all-U.S. portfolio leaves money on the table and concentrates risk in ways most investors don’t fully appreciate.

Here’s the wallet math: If the S&P 500 remains flat while international stocks gain 8% to 10%, an investor with $100,000 fully in U.S. equities earns nothing.

Someone with a 20% international allocation could see $1,600 to $2,000 in additional gains on that portion alone. Compounded over multiple years of international outperformance, the difference becomes substantial.

Apart from the raw returns, diversification also helps prevent currency exposure. When the dollar weakens, owning foreign-currency assets provides a natural tailwind. And international stocks, which are less tied to the AI/tech concentration that defines the S&P 500, can cushion your portfolio during a sector-specific drawdown.

As Maria Rahni of New York Life Investment Management told TheStreet, the goal isn’t to replace U.S. exposure but to complement it in a way that reduces reliance on one economic outcome or policy path.

How to add international ETFs to your portfolio without overcomplicating it

When I step back from Fidelity’s three screens and think about how I would translate their framework into concrete steps, I discovered the goal isn’t to overhaul your portfolio overnight. All you need to do is make simple, smart checks without being overly reliant on any one market.

Here’s a practical way of adding international ETFs to your portfolio.

• Audit your current allocation. Check what percentage of your portfolio is already international. Many target-date and balanced funds include some foreign exposure, so you may already have more (or less) than you think. If international stocks represent less than 15% to 20% of your equity allocation, there’s likely room to add.
• Decide between broad and targeted. A broad international ETF such as Vanguard Total International Stock ETF (VXUS) or iShares Core MSCI EAFE ETF (IEFA) gives you diversified exposure to developed and emerging markets in a single trade. That’s simpler and less volatile than single-country bets.
• Watch expense ratios, bid-ask spreads, and tracking error. Fidelity calls out these three cost layers, and all three matter. A low expense ratio doesn’t help if the bid-ask spread is wide (meaning you pay more to get in and out) or if the fund consistently misses its benchmark. Before buying, pull up two or three similar ETFs and compare all three metrics side by side.
• Don’t chase last year’s winner. European defense stocks surged by 65% or more in 2025. That doesn’t mean they’ll repeat in 2026; some are already trading above fair value. The strongest case for international investing is structural (valuation gaps, earnings convergence, dollar softening), not a short-term momentum trade. Buying into a region because it was hot last year is one of the most common and costly mistakes in ETF investing.
• Understand currency risk. International ETFs expose you to swings in foreign currencies. A weakening dollar boosts your returns; a strengthening dollar erodes them. Currency-hedged ETF options exist, but they add cost and eliminate one of the diversification benefits. For long-term investors with a 10-plus-year horizon, currency fluctuations tend to wash out over time, so hedging may not be necessary.

When going international backfires: common investing mistakes to avoid

International diversification is not a guaranteed win. There are real scenarios where this strategy underperforms or causes pain, and knowing them in advance can help you set realistic expectations.

• Dollar strength kills returns: If the Federal Reserve pauses rate cuts or the dollar surges on safe-haven demand, international stock returns get crushed on a currency-adjusted basis, even if local-market performance is strong. This happened consistently from 2011 to 2020, a period when U.S. stocks trounced international peers. The current dollar-weakening trend could reverse if geopolitical risk drives safe-haven flows back into the greenback.
• Political risk is real: Single-country ETFs carry outsized exposure to government policy shifts, capital controls, and geopolitical shocks. Brazil’s market, for example, can swing violently on fiscal headlines. Mexico’s equities face ongoing tariff uncertainty. If you hold country-specific funds, keep position sizes small enough that a 20% to 30% drawdown in one country won’t wreck your broader plan.
• Home-country bias: U.S. companies generate roughly 40% of their revenue internationally, per FactSet. Owning the S&P 500 already gives you meaningful global revenue exposure. International ETFs add geographic diversification of the companies themselves, which reduces concentration risk, but you’re not missing all global growth by staying domestic. The case for international isn’t that the U.S. is broken. It’s that paying 30x earnings for exposure you could get at 20x elsewhere doesn’t make portfolio sense.
• Overcomplicating with niche ETFs: Buying separate Germany, Japan, Brazil, and Chile funds creates a portfolio that’s hard to manage, expensive to rebalance, and difficult to keep in line with your target allocation. One or two broad international funds accomplish the diversification goal without the complexity. This is the same principle behind keeping your portfolio simple. The fewer moving parts, the less likely you are to make a costly behavioral mistake.

The bottom line on international stocks in 2026

Fidelity’s data show international stocks have momentum, a valuation advantage, and structural tailwinds from defense spending, corporate reforms, and commodity demand.

Fidelity is one of several major firms, alongside Vanguard, J.P. Morgan, BlackRock, and Morningstar, pointing investors toward non-U.S. equities.

That doesn’t mean you should sell your S&P 500 index fund tomorrow. But if 100% of your stock allocation sits in U.S. equities, you’re making a concentrated bet on one country at historically expensive valuations, while the rest of the world offers comparable earnings growth at significantly lower prices.

When I look at Fidelity’s framework and the broader Wall Street consensus, the practical takeaway is this: A 15% to 25% allocation to international equities is a reasonable starting point for most long-term investors.

The right number depends on your risk tolerance, time horizon, and existing holdings. Start by checking your current allocation, pick one or two low-cost, broad international ETFs, and rebalance gradually rather than making one large move.
