International ETF Investing
Expand your portfolio beyond US borders. Learn why international diversification matters, how to evaluate international ETFs, and the role of currency and geopolitical risk.
Prerequisites
We recommend completing these modules before starting this one:
Lesson 1: Why International Diversification Matters
The US stock market represents roughly sixty percent of global stock market capitalization, which means forty percent of the world's investable stock market exists outside US borders. By investing only in US stocks, you miss nearly half of the global economy. International diversification reduces portfolio risk because different countries and regions do not move in perfect lockstep. When the US market underperforms, international markets may perform better and vice versa. There have been entire decades where international stocks significantly outperformed US stocks, such as the 2000 to 2009 period when international developed markets returned substantially more than the S&P 500. While the 2010s favored the US heavily, no one knows which region will lead in the coming decade. Broad international exposure ensures you participate in growth wherever it occurs rather than betting everything on one country's continued dominance.
Key Point: Forty percent of the global stock market exists outside the US. International diversification ensures you participate in growth wherever it occurs rather than betting on one country.
Lesson 2: Types of International ETFs
International ETFs fall into three broad categories. Developed market ETFs like VEA (Vanguard FTSE Developed Markets) and EFA (iShares MSCI EAFE) invest in established economies like Japan, the United Kingdom, Germany, France, and Australia. These markets are well-regulated and relatively stable but may offer lower growth potential. Emerging market ETFs like VWO (Vanguard FTSE Emerging Markets) and EEM (iShares MSCI Emerging Markets) invest in developing economies like China, India, Brazil, Taiwan, and South Korea. These markets offer higher growth potential but come with greater volatility and political risk. Total international ETFs like VXUS (Vanguard Total International Stock) and IXUS (iShares Core MSCI Total International) combine both developed and emerging markets in a single fund, providing the broadest possible international exposure. For simplicity, a single total international ETF like VXUS is sufficient for most investors.
Key Point: For simplicity, a total international ETF like VXUS covers both developed and emerging markets in a single fund. You can add focused exposure to specific regions if desired.
Lesson 3: Understanding Currency Risk
When you invest in international ETFs, you are indirectly exposed to currency risk. If you buy a European stock ETF and the euro weakens against the US dollar, your returns are reduced even if the underlying European stocks performed well. Conversely, if the euro strengthens, you receive a currency boost. Over long periods of twenty or more years, currency effects tend to average out and are a relatively minor factor compared to stock returns. For this reason, most financial advisors recommend that long-term investors use unhedged international ETFs and accept the currency fluctuations. Currency-hedged ETFs exist, such as HEFA (iShares Currency Hedged MSCI EAFE), but they carry additional costs and eliminate the diversification benefit that different currencies provide. Only consider hedged ETFs if you have a shorter time horizon and want to isolate the stock returns from currency effects.
Key Point: Currency risk averages out over long periods. Most long-term investors should use standard unhedged international ETFs rather than paying extra for currency-hedged versions.
Lesson 4: How Much International Exposure Do You Need?
There is no single correct answer, but most guidance falls between twenty and forty percent of your stock allocation for international exposure. Vanguard recommends approximately forty percent based on global market capitalization weights. Other advisors suggest twenty to thirty percent, noting that US companies already generate significant international revenue through global operations. A simple approach is allocating thirty percent of your stock portfolio to international equities. If your total portfolio is eighty percent stocks and twenty percent bonds, that means twenty-four percent of your total portfolio in international stocks (thirty percent of eighty percent). The exact percentage matters less than having meaningful exposure. Even twenty percent in international stocks provides worthwhile diversification benefits. Avoid going below ten percent because at that level the allocation is too small to meaningfully impact your portfolio's risk and return characteristics.
Key Point: Allocate twenty to forty percent of your stock allocation to international equities. Even a twenty percent allocation provides meaningful diversification benefits.
Lesson 5: Evaluating Country and Geopolitical Risk
International investing introduces country-specific risks that do not exist with US investments. Political instability, government interference in markets, weaker property rights, capital controls, and regulatory unpredictability can all affect investment returns. Emerging markets carry more of these risks than developed markets. China, the largest emerging market, presents a notable example of how government policy can dramatically affect market returns. When evaluating international ETF exposure, consider the political stability of major holdings, the regulatory environment for foreign investors, and the fund's country concentration. Broad international ETFs mitigate country-specific risk through diversification across many nations. If you are concerned about specific country risk, check your ETF's country allocation in the fact sheet. Avoid concentrated single-country ETFs unless you have informed views and understand the elevated risks they carry.
Key Point: Broad international ETFs diversify across many countries, mitigating individual country risk. Avoid concentrated single-country bets unless you understand and accept the elevated risks.
