On June 15, COHERENT rose 5.71% in pre-market trading, trading at approximately $405.01/share, with turnover of $3.26 million.

On the news front, the stock had previously suffered a single-day plunge of over 11% on June 9 after SemiAnalysis published a bearish report on co-packaged optics (CPO), citing delayed commercialization timelines pushed to 2028-2029 versus market expectations of 2027 volume ramp, with core bottlenecks including low optical engine yields and high integration costs. Following consecutive sharp declines, oversold recovery demand has been accelerating. JPMorgan issued a hardware sector report on June 11 maintaining Overweight ratings on COHR, noting that the 20%+ pullback stemmed from excessive market pessimism on CPO deployment pace. Meanwhile, NVIDIA executives publicly refuted the bearish thesis, stating CPO will proceed with planned production expansion and deliveries in the second half, effectively countering panic sentiment.

Sector peer Corning rose 4.35% on the same day, with broader sector stabilization providing additional support. On the fundamental side, NVIDIA's $2 billion strategic investment agreement remains in execution, and demand for the company's 1.6T optical modules continues to surge, with long-term growth logic fundamentally unchanged.
