On October 12, Coherent declined 3.41% in regular trading, with shares changing hands at approximately $298.0 and turnover reaching $101 million.

The decline reflects continued pressure on the optical communications sector as market anxiety over the pace of AI hardware capital expenditure intensifies. A prior technical rebound failed to hold, and Coherent's shares retreated from earlier recovery highs, indicating that sentiment repair was not sustained.

Recent caution from overseas investors toward the AI hardware expansion narrative has weighed on the group. Factors including delays in data center construction due to power approval bottlenecks and elevated funding costs are compressing forward demand expectations, placing valuation pressure on optical communications as a strongly cyclical hardware segment.

Within the Electronic Components sector where Coherent belongs, the overall sector trend is lower. Among individual stocks, Corning fell 3.48%, Amphenol fell 1.02%, Vishay Intertechnology fell 4.11%, Littelfuse fell 1.80%, and Lightwave Logic fell 5.15%.
