Why Is Coherent (COHR) Stock Price Up 7.79% Today, August 17? AI Datacenter Demand Sparks Optics Rally

AI Market Summary
Coherent rallied ~7.8% as reports of indium phosphide substrate supply tightness and potential >10% Q4 price increases lifted the AI-datacenter optics complex, with peers also participating. The move appears driven more by supply-chain/demand read-through than a fresh COHR-specific operating catalyst; after-close 300mm SiC substrate sampling adds strategic context but not the session driver. Near-term focus shifts to optics breadth, input-cost risk, and execution/qualification timelines.
