On July 24, Coherent fell 3.31% in regular trading, trading at 302.9 USD/share, with turnover of $32.79 million. The broader optical communications sector came under pressure, with peer Corning declining 1.94% and Vishay Intertechnology falling 1.96%.

On the news front, Coherent had previously dropped over 21% from its July 10 high near $332 before entering an oversold recovery phase. The stock rebounded 3.15% in the prior session to approximately $322. Market strategists noted that after a sharp rebound ahead of earnings season, further upside becomes increasingly difficult, prompting some investors to lock in gains. The company announced it will release its fiscal Q4 results on August 12, with consensus EPS expected at $1.43, and the approaching earnings window has intensified short-term bull-bear dynamics.
