On June 23, COHERENT declined 3.17% overnight, trading at $412.8/share, with turnover of $9.5465 million.

On the news front, a bearish CPO research report published by SemiAnalysis on June 9 continues to ripple through the optical communication sector. The report argued that large-scale CPO commercial deployment has been delayed to 2028-2029, citing core bottlenecks including low optical engine yield rates, high co-packaging integration difficulty, and unfavorable system-level cost economics. Although NVIDIA executives publicly rebutted the timeline and JPMorgan maintained an Overweight rating, bull-bear divergence in the sector has intensified.

The stock had previously rallied over 7% intraday on June 22, fueled by catalysts including the groundbreaking ceremony for its Texas indium phosphide factory expansion — attended by NVIDIA CEO Jensen Huang — and a confirmed $50 million CHIPS Act subsidy. NVIDIA had previously invested $2 billion in Coherent with a long-term supply agreement. However, broader sector selling pressure dragged peers lower, with Corning falling 4.09% and Vishay Intertechnology declining 4.33%.
