How to Invest in International Stocks Beginner Guide

If your entire portfolio is made up of U.S. stocks, you are betting everything on a single country. That might feel safe because American markets have performed well in recent years, but history tells a different story. International stocks have outperformed U.S. stocks in roughly half of all decades since 1970, and ignoring them means leaving real diversification on the table.

Learning how to invest in international stocks does not require a finance degree or a complicated brokerage setup. In this guide, you will learn exactly which funds to buy, how much to allocate, and what risks to watch for. By the end, you will have a clear plan to build a globally diversified portfolio that can weather any market environment.

Why International Stocks Belong in Your Portfolio

The United States represents roughly 60 percent of global stock market value. That leaves 40 percent of the world's investable companies sitting outside American borders. When you skip international stocks, you miss out on thousands of profitable businesses in Europe, Asia, and beyond.

Diversification is the core reason to invest in international stocks. When U.S. markets struggle, international markets sometimes hold steady or even rise. This was clearly visible during the 2000 to 2009 decade, when U.S. large-cap stocks returned virtually nothing while international developed markets delivered meaningful positive returns.

There is also a valuation argument. As of early 2026, many international stock markets trade at lower price-to-earnings ratios than the S&P 500. Lower starting valuations have historically correlated with stronger future returns over 10-year periods.

If you are just starting to think about spreading your money across different assets, our guide on how to diversify your investment portfolio on a budget covers the foundational principles. International exposure is one of the most impactful diversification moves you can make.

Best Ways to Buy International Stocks

The simplest and most cost-effective way to invest in international stocks is through exchange-traded funds. A single international stock ETF can give you exposure to thousands of companies across dozens of countries for an expense ratio well under 0.15 percent. No need to research individual foreign companies or worry about trading on overseas exchanges.

Here are the most popular options for beginners:

• Total International Stock ETFs are the broadest choice. Vanguard's VXUS and iShares' IXUS both track the FTSE Global All Cap ex US Index or its equivalent. They hold stocks from developed and emerging markets alike, giving you one-fund international coverage.
• Developed Market ETFs focus on established economies like Japan, the United Kingdom, Germany, and Australia. Vanguard's VEA and iShares' IDEV are solid choices here. These funds tend to be less volatile than emerging market funds while still providing meaningful geographic diversification.
• Emerging Market ETFs target faster-growing economies such as China, India, Brazil, and Taiwan. Vanguard's VWO and iShares' IEMG are the leading options. They carry more risk but also offer higher growth potential over long time horizons.

If you are still deciding between fund structures, our comparison of index funds vs ETFs can help you choose. Both work well for international investing, though ETFs tend to offer slightly more flexibility for smaller accounts.

To get started buying any of these funds, you will need a brokerage account. If you have not opened one yet, check out our walkthrough on how to open your first brokerage account in 2026. Most major brokers now offer commission-free ETF trading.

Understanding Currency Risk

When you invest in international stocks, you are not just betting on foreign companies. You are also taking on currency exposure. If the euro falls 5 percent against the dollar, your European stock returns shrink by roughly that amount, even if the underlying stocks performed well.

Currency fluctuations can add or subtract 2 to 5 percentage points from your international returns in any given year. Over short periods, this creates extra volatility that can feel uncomfortable. Over longer periods, though, currency movements tend to wash out and become less significant.

Should you hedge your currency risk? For most beginners, the answer is no.

Currency-hedged international ETFs exist, but they come with higher expense ratios and added complexity. The natural diversification benefit of holding foreign currencies actually works in your favor during periods when the U.S. dollar weakens.

The best way to manage currency risk is simply to maintain a long time horizon. If you are investing for goals 10 or more years away, short-term currency swings become noise rather than a real threat. Pairing international investing with a dollar-cost averaging strategy helps smooth out both stock price and currency fluctuations over time.

How Much to Allocate to International Stocks

Financial advisors and major investment firms generally recommend allocating 20 to 40 percent of your stock portfolio to international holdings. Vanguard's own research suggests 40 percent as optimal for minimizing volatility, while other firms like Fidelity and Schwab lean closer to 20 to 30 percent. There is no single perfect number, but staying within this range gives you meaningful diversification.

A simple starting point is the 70/30 split. Put 70 percent of your stock allocation into a U.S. total market fund and 30 percent into a total international stock fund. This gives you broad global coverage without overcomplicating your portfolio.

If you want to match the global market exactly, you would allocate roughly 60 percent to U.S. stocks and 40 percent internationally. This market-cap weighted approach means you own the world in proportion to each country's actual market size. It is a perfectly rational strategy, though some investors prefer a modest home-country tilt toward U.S. holdings.

As you build out your full portfolio, international stocks are just one piece of the puzzle. Our step-by-step guide to building your first investment portfolio shows how to combine domestic stocks, international stocks, and bonds into a cohesive plan.

The key is to pick an allocation and stick with it. Rebalance once or twice a year to maintain your target percentages. Resist the urge to chase whichever region performed best last year.

Developed Markets vs Emerging Markets

Not all international stocks are created equal. The distinction between developed and emerging markets matters for both risk and return expectations. Understanding this split helps you make smarter allocation decisions.

• Developed markets include countries with mature economies, stable political systems, and well-regulated financial markets. Think Japan, the United Kingdom, Canada, Germany, France, Australia, and Switzerland. Stocks in these markets tend to behave somewhat similarly to U.S. stocks, with moderate volatility and established dividend traditions.
• Emerging markets include countries with rapidly growing economies but less mature financial infrastructure. China, India, Taiwan, Brazil, South Korea, and South Africa are among the largest. These markets have historically delivered higher long-term returns but with significantly more volatility along the way.

According to data from MSCI, emerging markets have generated annualized returns of roughly 10 percent since 1988, though with drawdowns that can exceed 50 percent during crises. Developed international markets have been less volatile but also less explosive on the upside.

For most beginners, a total international stock ETF that blends both categories is the easiest approach. These funds typically hold about 75 to 80 percent in developed markets and 20 to 25 percent in emerging markets. This built-in mix gives you growth potential from emerging economies while keeping the bulk of your international allocation in more stable markets.

If you want to tilt more aggressively toward emerging markets, consider adding a small dedicated emerging market ETF on top of your core international fund. A common approach is to hold 25 to 30 percent of your international allocation in emerging markets specifically. Just be prepared for wider swings in value and commit to holding through the inevitable downturns.

Frequently Asked Questions

Can I invest in international stocks through my 401(k)?

Yes, most 401(k) plans offer at least one international stock fund. Look for options labeled "international equity," "global ex-US," or "foreign stock" in your plan menu. If your plan has limited choices, even a small allocation to whatever international option is available is better than none.

Are international stocks riskier than U.S. stocks?

International stocks can be more volatile in the short term, especially emerging market holdings. However, combining U.S. and international stocks actually reduces overall portfolio risk because the two do not move in perfect lockstep. The diversification benefit means your total portfolio becomes more stable, not less.

Do I need to worry about foreign taxes on international stock dividends?

Foreign governments do withhold taxes on dividends paid to U.S. investors, typically between 10 and 30 percent depending on the country. However, you can claim a Foreign Tax Credit on your U.S. tax return to offset most or all of this withholding. Holding international funds in a taxable brokerage account rather than an IRA maximizes your ability to use this credit.
