On August 24, Coherent fell 5.25% in regular trading, trading at $267.745/share, with turnover of $142 million.

On the news front, peer Applied Optoelectronics announced plans to raise $600 million through an at-the-market (ATM) equity offering, marking its third such fundraising initiative this year. The move triggered widespread concerns over the optical communications sector's capital structure and cash flow sustainability, driving Coherent, Lumentum, and other sector names sharply lower.

The selling pressure compounds an already fragile technical backdrop. Coherent has declined over 20% since August 18, when a surge in global long-term bond yields — with the US 30-year Treasury yield touching 5.337%, a 19-year high — hammered high-valuation technology stocks. An attempted technical rebound on August 21 of nearly 4% quickly faded. Despite strong Q4 fiscal results showing revenue of $2.05 billion (up 34% YoY) and adjusted EPS of $1.74 (up 74% YoY), prior accumulated gains have led to concentrated profit-taking.

Within the Electronic Components sector, Corning fell 4.37%, Vishay Intertechnology fell 2.91%, Lightwave Logic fell 3.96%, Amphenol fell 2.36%, and Littelfuse fell 1.79%.
