S&P 500 Gains 1.2% for the Week; Nasdaq 100 Adds 0.2%
AI take
The headline index gains mask a sharp rotation beneath the surface: semiconductors and memory chips sold off hard while the Magnificent Seven held up, suggesting the week's strength came from breadth and defensives rather than the AI trade that has driven the tape. Friday's single-name dispersion — Moderna's double-digit jump against steep declines in T-Mobile, Arm and Comcast — points to stock-specific catalysts, not a uniform risk-on move. Whether the chip complex stabilizes or the rotation into megacap and non-tech names continues is the open question.
