On July 31, Coherent rose 5.88% overnight, trading at $263.7/share, with turnover of $104,400. The stock extended the prior session's 10.73% intraday rebound as the optical communication sector continued to recover from a prolonged selloff.

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 that triggered a sector-wide rout on July 28, with Coherent falling over 12% in a single session. After multiple days of selling pressure absorption, the sector broadly recovered on July 30, with Corning rising 6.71% and Belden surging 9.98%, signaling that oversold repair momentum had taken hold. This rebound momentum carried into the overnight session.

Coherent is scheduled to release its fourth fiscal quarter earnings on August 12, with consensus EPS expected at $1.43, as the approaching earnings window continues to intensify positioning activity between bulls and bears.
