Coherent Corp (COHR) shares declined 8.92% to close at $304.73, driven by broad profit taking across the optical component sector. The sell-off follows a year of extraordinary gains, with pressure landing hardest on names that have run furthest.
What Happened
The decline occurred as a group of optical makers, including Applied Optoelectronics and Lumentum, were sold off. Applied Optoelectronics dropped 9%, while Lumentum slid 4%, reflecting a sector-wide correction. This move comes despite recent industry reports indicating the VCSEL market is projected to reach $1.96 billion by 2032, driven by AI data centers and 3D sensing in smartphones. Coherent remains a key player in this space, alongside Lumentum and ams-OSRAM.
