COHR is trading at 4.1% down now at $353.45 after a sharp July 1 selloff. The move aligns with weaker tech sentiment, while no new company-specific announcement appears in the available news flow.
The stock was already under pressure after a 5.9% pre-market drop on July 1, and the latest price action extends that weakness. Broader tech softness and AI-sector caution are the most likely drivers, not a clearly identified Coherent-specific event.
