US Equities: What’s Hiding Beneath the Market’s Headline Returns?

US equities have continued to rise, but the gains are still being driven by a narrow group of AI-linked mega-cap stocks. Beneath that headline strength, earnings revisions are improving across a wider set of companies, suggesting the market may be overlooking more diverse opportunities.

At the same time, stock-level dispersion is increasing and correlations are falling, which means individual company fundamentals matter more than broad index trends. That creates a stronger case for active stock selection and a broader approach that includes AI leaders, adopters of AI, and businesses with less direct exposure to disruption.

The main risk is valuation: many technology leaders already price in very high expectations for future AI growth. If spending slows or profitability disappoints, leadership could shift quickly and leave concentrated positions vulnerable.
