On June 23, COHERENT fell 5.05% in pre-market trading, trading at $395.5/share, with turnover of $4.0232 million. The decline comes after the stock had rallied sharply in prior sessions, gaining over 7% intraday on June 22, driven by the Sherman indium phosphide factory expansion groundbreaking and CHIPS Act subsidy catalysts.

On the news front, the pullback is primarily attributed to a bearish CPO research report published by SemiAnalysis on June 9, whose negative implications continue to reverberate across the sector. The report indicated that large-scale commercial deployment of co-packaged optics has been delayed to 2028-2029, citing low optical engine yields and high co-packaging integration difficulty as core bottlenecks, intensifying bull-bear divergence across the sector.

Within the Electronic Components sector, broad-based weakness is evident. Corning fell 6.83%, Vishay Intertechnology dropped 6.08%, and Amphenol declined 3.22%, reflecting sector-wide profit-taking pressure following the recent rally fueled by the NVIDIA partnership and CHIPS Act funding announcements.
