How Long Can the Recent International Outperformance Continue?

After more than a decade of U.S. dominance, the tone has shifted, and investors understandably want to know whether this is a brief rebound—or the start of a new leadership cycle. While we do not time markets or make predictions, we believe long-term investors can benefit from maintaining international exposure by understanding the broader structural forces that have historically shaped these cycles.

A Clear Break from the Last Cycle

Following an extended stretch of U.S. outperformance, 2025 marked a meaningful turning point. International equities significantly outpaced U.S. markets:

  • MSCI World ex-U.S.: ~33%
  • MSCI ACWI ex-U.S.: ~33%
  • S&P 500: ~18%

This type of relative shift could mark the early stages of a renewed cycle of international market leadership, as history shows leadership tends to move in long arcs shaped by macroeconomic regime shifts—policy, rates, currency, and earnings composition—rather than short-term sentiment. The current phase of international strength may persist, supported by more attractive relative valuations, a softer U.S. dollar, and broadening global earnings growth.

What History Tells Us: Cycles Tend to Run Long

The five-year rolling relative returns between the S&P 500 and MSCI World ex-U.S. highlight multi-year cycles of leadership.
