COHH is trading 3.2% up in after-hours trading, with the rebound reflecting renewed positioning in optical-AI and photonics stocks ahead of Coherent’s earnings.

  • COHH is effectively concentrated in Coherent exposure after the August 10 selloff.
  • Coherent is scheduled to report fiscal fourth-quarter results after the August 12 market close.
  • The broader market is slightly risk-off ahead of the August 12 CPI release, but volatility and speculative repositioning better explain the move than macro conditions.
