On September 24, Coherent declined 3.12% in pre-market trading, trading at $291.0/share, with turnover of $3.6052 million. The stock extended its multi-session slide as the broader optical communication sector continued to face selling pressure.

The decline was driven by persistent concerns over slowing AI computing power demand, which have weighed on the entire optical communication sector for several consecutive sessions. On September 24, peers including Astera Labs and Credo fell over 2%, while Corning and Applied Optoelectronics dropped over 1% in pre-market trading. Market participants remain cautious about the sector's elevated valuation — with a trailing P/E ratio around 77x — and potential supply-demand imbalances beyond the near term. Despite a series of company-level positives, including the launch of the PhotonLink integrated optics platform, new optical technologies showcased at ECOC, and Deutsche Bank initiating coverage with a top-pick designation, these fundamental catalysts have been insufficient to offset the broader sector-wide risk-off sentiment.

Within the Electronic Components sector, Amphenol fell 2.4%, Corning fell 2.75%, and Vishay Intertechnology declined 1.99%.
