On September 1, Coherent fell 3.33% in regular trading, trading at 270.93 USD/share, with turnover of approximately $71.54 million. The decline came as the optical communication sector continued to face broad profit-taking pressure that has persisted since late August.

The selling wave across the sector was triggered after the catalyst effect from NVIDIA's earnings report faded, prompting investors to lock in gains. In the prior session, peers Applied Optoelectronics and Lumentum each dropped roughly 6%, while Coherent fell over 5%. With Coherent having accumulated a year-to-date gain exceeding 60%, and its most recent quarterly earnings report sparking market divergence over profit margin performance, short-term pullback pressure has intensified.

Within the Electronic Components sector, weakness was broadly evident. Among individual stocks, Corning fell 2.3%, Vishay Intertechnology fell 3.12%, Belden fell 0.4%, Littelfuse fell 0.24%, while Amphenol edged up 0.14%.
