An investor argues that the S&P 500's 150% cumulative outperformance versus developed market equities over 15 years stems primarily from currency tailwinds and valuation expansion rather than superior fundamental growth. While the Magnificent Six delivered exceptional returns, the median S&P 500 company generated only 4.0% annualized fundamental returns in the five years ending December 2024—the lowest since the mid-1980s. The author contends U.S. companies face three simultaneous negative supply shocks: tariffs raising costs, immigration restrictions constraining labor supply, and policy uncertainty deterring investment. International equities, trading at 33–55% discounts to U.S. peers despite similar expected growth, offer more attractive valuations and face less severe macroeconomic headwinds.
