Value Vantage Point: Why Currency Diversification Matters

Many US investors are overweight US equities, making them also overweight US-dollar exposure. Given recent international equity market outperformance versus US equities as well as a weakening greenback, could it be time to reconsider that asset mix? We think diversifying makes sense, particularly given the US-dollar headwinds from a potential increase in US debt-to-GDP (gross domestic product), lower interest rates, fading US exceptionalism and the strengthening of non-US economies such as Europe and Japan. These factors could reverse both the long-term strength of the US dollar and US outperformance trend, leaving behind the undiversified.

The US market: It’s more concentrated than you think

It’s no secret that US investors love US companies. In the United States, people have more than six times as much money invested in US names than in those domiciled overseas (Exhibit 1). As money has poured into large-capitalization companies, the S&P 500 Index has become increasingly concentrated in information technology companies, with the Magnificent Seven1 big-tech names growing their share to a third of the overall index (Exhibit 2). This concentration creates a lot of risk exposure to both the domestic business cycle and the US dollar (USD).
