Coherent Shares Slide 3.12% Amid 52.5% Volume Drop Ranking 227th in Market Activity

On August 18, 2025, Coherent (COHR) closed with a 3.12% decline, while its trading volume of $0.4 billion marked a 52.5% drop from the previous day, ranking it 227th in market activity. The stock’s performance reflects mixed sentiment ahead of broader market volatility.

Rosenblatt Securities recently adjusted its price target for Coherent to $135 from $150 but maintained a "Buy" rating following the firm’s fiscal Q4 earnings. The firm noted Coherent’s conservative guidance practices and acknowledged competitive pressures from rivals like Lumentum, which has shown stronger near-term growth in laser chips and optical component sales. However, Rosenblatt anticipates Coherent will regain ground in key AI optical categories by FY26 and FY27, emphasizing long-term industry execution potential for both companies.

A backtest of a strategy purchasing the top 500 stocks by daily trading volume and holding them for one day from 2022 to the present yielded a total profit of $2,340. This corresponds to a cumulative return of 23.4% on the initial investment, indicating modest gains amid market turbulence and a conservative approach.
