On September 3, Coherent fell 3.58% in regular trading, trading at $256.71/share, with turnover of $91.31 million.

On the news front, optical communications peer Credo Technology plunged over 20% in the prior session, with the core catalyst being market disappointment over its optical product revenue forecast, compounded by a 370-basis-point sequential decline in GAAP gross margin and further downward guidance for Q2 gross margins. The selloff triggered broad-based pressure across the optical communications sector.

Coherent had previously accumulated gains exceeding 60% year-to-date. Although its mid-August earnings report delivered across-the-board beats, profit margin performance sparked market divergence, sustaining profit-taking pressure. Within the Electronic Components sector, the broader industry tilted weak, with Corning down 2.67%, Vishay Intertechnology down 1.40%, Lightwave Logic down 1.19%, and Rogers down 1.15%.
