On July 31, Coherent rose 10.26% in regular trading, trading at $278.93/share, with turnover of $150 million. The stock extended its prior session's 10.73% intraday rebound as the optical communications sector continued to release oversold recovery momentum following consecutive steep declines.

On the news front, the sector had been under sustained pressure since the Philadelphia Semiconductor Index plunged over 4% on July 25, compounded by Corning's disappointing Q3 guidance with core sales forecast of $4.9-5.0 billion, whose midpoint of $4.95 billion fell slightly below consensus. After multiple sessions of selling pressure digestion, the sector broadly recovered starting July 30, with peers Vishay Intertechnology up 8.12%, Corning up 7.72%, Amphenol up 3.71%, and Belden up 3.29%, demonstrating a pronounced sector-wide rebound pattern. Coherent is scheduled to report Q4 fiscal year earnings on August 12, with consensus EPS expected at $1.43.
