US chip stocks open lower as PPI data eases rate concerns

The split inside semiconductors is the story: a benchmark down 1% while Nvidia and Cerebras rally suggests rotation rather than a sector-wide de-rating, with AMD, CoreWeave and Nebius absorbing the selling. PPI easing rate anxiety is a macro tailwind, yet it clearly isn't lifting every name, so sensitivity to rates is no longer the main differentiator among these companies. Whether this dispersion persists — and whether the laggards keep diverging from the leaders — is the open question worth watching.
