From US Concentration to Global Opportunity—Staying Invested While Preparing for Volatility

Overview

In our recent publications, “From US technology leadership to US small caps and emerging markets,” (January 2026) and “Get ready for a broader US market,” (January 2025) we highlighted a setup that is rare but powerful: strong economic growth, broad earnings participation and unusually high market concentration.

Historically, this combination creates fertile ground for market broadening—away from a narrow group of leaders and toward international equities, small-capitalization stocks and less-favored sectors within the United States.

This process was quietly underway through most of 2025 and became more dynamic in recent months. We believe this global rotational bull market can persist over the coming years. However, markets rarely move in straight lines. Even in healthy bull markets, higher volatility and periodic pullbacks are normal—and often create the best opportunities to add risk at more attractive prices.

One framework, two plausible market paths

From a strategic perspective, we view the current environment through the lens of two plausible market paths: Map A and Map B. These are not competing forecasts. They are two components of the same investment framework.

Map A: Broadening within a supportive macro backdrop

Map A reflects the environment markets are currently pricing. It assumes:

  • Continued support from monetary and fiscal policy
  • Strong productivity gains, including gains from technological adoption
  • Resilient gross domestic product (GDP) growth with inflation contained
  • High expectations for earnings growth
  • Geopolitical risks that are largely priced in, deferred or ignored

Under this scenario, market leadership has continued to broaden, volatility has remained contained, and a constructive macro and liquidity backdrop has supported risk assets. This framework helps explain why markets have remained resilient despite recurring policy uncertainty and ongoing geopolitical risks. Notably, several major US indexes have reached new all-time highs this year, with the S&P 500 Equal Weight Index and value stocks leading the advance.
