On September 1, Coherent fell 3.09% in pre-market trading, trading at 269.2 USD/share, with turnover of approximately $13.74 million. The decline extended a multi-session pullback across the optical communications sector.

The sell-off reflects ongoing profit-taking pressure after the Nvidia earnings catalyst from late August faded. In the prior trading session, Applied Optoelectronics and Lumentum each fell approximately 6%, while Coherent dropped over 5% and Corning declined 2%. With Coherent having accumulated a year-to-date gain previously exceeding 60%, diverging views on the company's margin trajectory have amplified short-term correction risks. Multiple analysts have flagged the stock's forward P/E ratio of roughly 31.5x as significantly above the industry average of 21.2x, contributing to valuation-driven selling.

Within the Electronic Components sector, the overall tone remained weak. Corning fell 3.22%, Vishay Intertechnology fell 2.32%, Belden fell 2.15%, Amphenol fell 1.26%, and Littelfuse fell 0.77%.
