Coherent is trading 12.44% lower at $171.00, with pressure across semiconductor and AI-infrastructure stocks the clearest explanation for its reversal.

  • The shares are down from the November 4 close of $195.09.
  • Coherent beat earnings and revenue estimates, and current-quarter guidance was above estimates; reports described an initial post-earnings gain.
  • Sector pressure reflects investor reassessment of data-center regulation and investment prospects after the election, alongside weak smartphone-chip demand at Qualcomm.
