In May 2026, following the earlier rapid rebound, US equities entered a phase in which trend continuation coexisted with growing structural dispersion. Technology stocks continued to outperform, and the earnings power of the AI value chain kept strengthening. Guidance from leading companies on both results and capital expenditure further reinforced confidence in medium- to long-term growth. At the same time, capital began broadening out from a small number of mega-cap technology names into a wider range of AI-related subsegments, leading to improved market breadth.
From a trading-structure perspective, May was not a broad-based rally, but rather a structural market with a clear dominant trend and faster internal rotation. The AI theme and earnings growth continued to support the technology sector, yet internal performance differences remained significant. Sticky inflation, high rates, and uncertainty around the policy path still constrained valuation expansion, which means the market was not being driven purely by sentiment. Instead, it became increasingly important to assess trend strength, the rhythm of style rotation, and changes in volatility.
We continue to believe that AI is the most important medium- to long-term theme in US technology assets, but the market's focus is shifting from sheer scale of investment toward earnings realization, capital efficiency, and commercial progress. Ongoing improvements in model capability, lower inference costs, and expanding application scenarios should continue to support industry growth. In the near term, the long-term thesis for technology equities remains intact, but repeated sector rotation and volatility are likely to persist. Such an environment, where the direction is clear but market opinions remain divided, can be especially favorable for quantitative strategies that dynamically adjust to capture structural alpha.
