On September 22, Coherent declined 3.77% in regular trading, trading at $307.28/share, with turnover of approximately $105 million. The selloff reflects a sector-wide pullback across optical communication stocks driven by growing concerns over a near-term slowdown in AI computing infrastructure demand.

Despite a string of company-specific positives — including the launch of an enhanced Pluggable Optical Line System (POLS) now in full-scale production, new AI optical technologies showcased at ECOC, and Deutsche Bank initiating coverage with Coherent as a top pick — the broader industry-level risk sentiment overwhelmed individual catalysts. The enhanced POLS supports 800G ZR/ZR+ modules and delivers up to 25.6 Tbps per fiber pair across 2–200 km links.

The decline was mirrored across the optical communication sector: AXT fell nearly 3%, Credo dropped over 2%, while Lumentum, Corning, and Astera Labs each declined over 1%. Market participants appear to be repricing near-term AI infrastructure spending expectations, creating systematic pressure that company-level fundamentals have so far been unable to offset. Analysts maintain a 12-month average target price of approximately $415 for Coherent, suggesting meaningful upside from current levels.
