On July 15, Coherent fell 3.39% in regular trading, trading at 299.025 USD/share, with turnover of approximately $157 million. The decline came as the optical communications sector faced renewed selling pressure, with industry peer Corning dropping over 7%.

The optical communications sector had briefly rebounded on July 14 driven by semiconductor strength, with Coherent gaining 3.14% that day, but the recovery failed to sustain. Since July 10, the sector has experienced alternating pullbacks and rebounds. Coherent's stock has now retreated over 9% from its $332 area, reflecting significant short-term profit-taking pressure as prior gains are digested.

Within the Electronic Components sector, Corning fell 7.19%, Vishay Intertechnology fell 0.48%, Amphenol rose 0.07%, Littelfuse rose 0.58%, and Amplitech Group rose 1.42%.
