COHR is trading 3.5% down at $367.91 as investors continue to reassess high-flying AI and semiconductor names amid recent sector volatility.

  • The move extends yesterday’s sharp 10.4% drop on June 23, 2026, as the broader AI-tech rout continues.
  • There are no fresh company-specific headlines this morning; the decline appears driven by valuation reset pressure following a massive run-up over the past year.
