Philadelphia Semiconductor Index Rises Over 5%; Nvidia Falls 3.89%

The breadth of the move—nearly every major chip name higher while Nvidia fell—suggests rotation rather than a uniform sector bid. That divergence matters because Nvidia has been the index's dominant weight; a broad rally without it points to money spreading into laggards like AMD, Broadcom and Micron rather than fresh conviction in the AI leader. Whether the dispersion persists, or Nvidia's weakness eventually drags the group, is the open question worth watching.
