On June 16, COHERENT fell 3.04% in regular trading, trading at $399.695/share, with turnover of $542 million. The stock remains under pressure from the lingering impact of SemiAnalysis's bearish CPO report published on June 9.

The report argued that large-scale CPO commercial deployment has been delayed to 2028-2029, significantly later than the market's prior consensus of a 2027 full-scale ramp. Core bottlenecks cited include low optical engine yield, high co-packaging integration complexity, and unfavorable total system cost versus traditional pluggable optical modules. COHERENT plunged over 11% on June 9 following the report's release.

Although NVIDIA executives publicly rebutted the findings, stating CPO expansion and delivery remain on track for the second half of this year, and JPMorgan maintained its overweight rating, bull-bear divergence has intensified again following last week's oversold recovery rally. Within the sector, Corning fell 4.46% on the same day, reflecting sustained selling pressure across optical communications names.
