Coherent is trading 10.08% up at $361.68 after rival Lumentum reported better-than-expected fiscal fourth-quarter results and stronger first-quarter guidance, signaling continued demand for optical-networking equipment.

  • Investors are positioning ahead of Coherent’s fiscal fourth-quarter and full-year results, scheduled after the market closes on August 12.
  • The broader semiconductor rally adds support, but the primary catalyst is the photonics-sector read-through from Lumentum.
