COHH is trading at $8.54, up +7.83%, primarily after Coherent reported record fourth-quarter revenue of $2.05 billion and adjusted EPS of $1.74. - The move on August 17, 2026, extends COHH’s leveraged rebound. - Coherent’s fiscal Q1 2027 revenue guidance of $2.2–$2.4 billion exceeded expectations, reinforcing optimism around AI data-center and optical-communications demand. - Broader markets are relatively mixed; the move appears primarily tied to the semiconductor and AI-optics sector rather than a broad risk-on rally.
