Coherent Shares Slide Pre-Market as Optical Stocks Pull Back Across AI Photonics Chain
Coherent Inc. shares dropped about 4.5% in pre-market trade to $389 as U.S. optical communication stocks retreated broadly. The pullback affected suppliers across the AI photonics supply chain and comes amid concerns about co-packaged optics adoption timelines, a lack of near-term catalysts and renewed profit-taking on an elevated valuation.
