On October 13, Coherent fell 3.83% in Regular Trading, trading at $277.44/share, with turnover of $140.0 million.

The move came as optical communications shares extended their pullback, with market concern continuing to center on the pace of AI infrastructure upstream hardware spending. Recent market commentary indicated that worries over data center power-approval delays and higher funding costs were pressuring longer-term demand expectations, weighing on valuation across cyclical optical hardware names.

Recent context showed Coherent had participated in a brief sector rebound on October 9, helped by improved sentiment after reports that Lumentum optical component orders were booked out to 2029. That recovery did not hold, and subsequent trading on October 12 already pointed to renewed weakness in optical communications stocks, setting the backdrop for the latest decline.
