SMH is trading at $609.12 (+1.52%) in a rebound from its September 28 close of $600.01.

  • On September 28, semiconductor shares faced AI-demand worries and broader pressure from higher oil prices and Treasury yields.
  • There is no clearly verified fresh sector-wide catalyst for the September 29 morning gain.
  • The prior session’s sharp AMD rally and strength in technology shares offer possible support; Nvidia-specific buyback news is another positive chip-sector backdrop.
