Too Much of a Good Thing in America? The Case for Going Global

An allocation to the MSCI Global All-Country World Index 10 years ago would have been 53% invested in the United States. Today, that U.S. exposure would represent 63% of the investment. This imbalance reflects great returns – and great risk.1

Global diversification has always been a cornerstone of disciplined portfolio construction. True diversification means owning assets that do not all move together. Developed international markets, including Europe, Japan and the United Kingdom, as well as emerging markets such as Brazil, India and South Korea, have historically exhibited lower correlation to U.S. large-cap equities than many domestic alternatives. When concentrated risks in the U.S. market, whether driven by a handful of mega-cap technology stocks or domestic policy uncertainty, weigh on returns, international exposure can serve as a meaningful stabilizer. The valuation case is also compelling. International equities remain attractively priced relative to their U.S. counterparts. Emerging market equities, even after strong 2025 performance, trade at approximately 10.6 times forward earnings,2 a discount of just under 50% to U.S. valuations.

Developed international markets similarly trade well below long-term averages relative to the U.S. For valuation-conscious investors, that gap represents opportunity.

We remain mindful that clients should generally match their U.S. dollar assets to their U.S. dollar liabilities and carefully consider the tax consequences of diversifying appreciated positions. (Please see the recent article by Jon Kropf on balancing tax and diversification considerations, “Long-Term Gains: A Good Problem but a Problem Nonetheless”. Those considerations matter, particularly for taxable investors, but they should be weighed alongside the long-term benefits of reducing concentration risk and expanding exposure to the full global opportunity set.

Our international equity allocation is a commitment to the principle that a well-constructed portfolio reflects the full opportunity set of the global economy. The companies, economies and currencies of the world beyond our borders represent more than half of global economic output. While we remain broadly overweight the United States, we continue to rebalance portfolios, striving for an international allocation of at least 15% as appropriate.

Our approach to international investing has generally been to invest with active managers, although we are now pairing those managers with a low-cost, passive exposure to global markets excluding the United States. We also maintain direct exposure to Japan through a currency-hedged ETF that provides exposure to Japanese companies – particularly export-oriented businesses – while reducing the volatility of the yen.

Maintaining diversification discipline through shifting market cycles is, we believe, one of the most effective ways to protect and grow portfolios over the long term.
