COHH is trading at $6.60 (-3.37%) after-hours as surging Treasury yields pressure growth-stock valuations.

  • Expiring U.S.-Iran ceasefire hopes lifted oil and renewed inflation concerns, worsening risk sentiment.
  • Semiconductor stocks fell broadly; the Philadelphia Semiconductor Index declined about 5%, with AI names under pressure.
  • COHH’s 2x exposure to Coherent amplifies weakness in AI-photonics and semiconductors; no new negative Coherent-specific announcement was identified, and the decline most likely reflects continued sector and macro risk aversion after the August 18 selloff.
