On July 13, Coherent fell 3.85% in regular trading, trading at $311.95/share, with turnover of $156 million. The stock extended its pre-market weakness, where it had already declined over 3%, as the broader optical communication sector came under sustained selling pressure.

On the news front, U.S.-listed optical communication stocks saw widespread declines on the day, with Corning and Astera Labs falling over 6%, Applied Optoelectronics and Credo dropping over 5%, and Lumentum, Ciena, and Coherent all declining over 3%. The sector has been retreating since July 10, with the semiconductor complex broadly weakening and dragging related names lower. Coherent had previously rebounded from around $304.3 to the $332 area, and short-term profit-taking pressure has intensified amid the sector-wide pullback.

Within the Electronic Components sector, Corning fell 4.84%, Vishay Intertechnology fell 5.73%, Amplitech Group fell 5.68%, Amphenol fell 1.03%, and Littelfuse fell 0.51%.
