Going Abroad for a Free Lunch

From the 1970s to the mid-1990s, 12-month correlations between U.S. and international equities averaged 0.47. U.S./international correlations have increased significantly since then, a period that saw the signature events of the globalization era – the establishment of the World Trade Organization (WTO), National American Free Trade Agreement, the launch of the Euro, and China’s admittance to the WTO in 2001. Not only was this period characterized by higher trade flows, but it also saw higher capital flows across borders. These factors led to increased correlation in asset prices across countries thereby reducing the value of international diversification. Correlations during the peak globalization era averaged 0.83.

However, since 2016, as evidenced by Brexit and the first U.S./China trade war, we have seen a rise in economic nationalism and the erection of barriers to cross-border movement of goods, capital, and labor. The fragmentation of global supply chains and re-shuffling of trading relationships that started in 2016 is accelerating with the chaotic rollout of the second Trump Administration’s trade policies, increasing the benefits of international diversification as correlations decline.

The biggest pushback we often hear when extolling the diversification benefits of international equities is that “clients can’t eat” risk-adjusted returns. Many investors will shrug off risk as long as their returns are strong. Or said differently, it is the destination that matters, not how circuitous the route is that gets you there. In theory, they have a point. But in practice, the most thoughtful and effective investment plan is rendered useless if a client is unable to stick with the program because of excessive volatility. Even at peak correlations, we believe an allocation to international equities is still an effective diversifier and volatility dampener and thus deserves a place in client portfolios.

Portfolio standard deviation is a statistical measure that indicates the volatility or risk of a portfolio of investments. It represents the average amount by which the portfolio's returns deviate from its mean return. A higher standard deviation means greater volatility, and a lower standard deviation indicates lower volatility. Correlation measures the degree to which two variables are linearly related, calculated on a scale from -1.0 to 1.0.
