On September 16, Coherent rose 3.98% in regular trading, trading at approximately $281.30 per share, with turnover of $99.30 million. The rebound came after the stock plunged 12.73% in the prior session, when three major AI leaders publicly called for slowing AI development, triggering a broad selloff across optical communications names.

On the news front, Citi released a report stating that the recent semiconductor pullback presents a rare buying opportunity, arguing that market concerns over AI spending deceleration are clearly overdone. Citi noted that sustained growth in AI inference demand, combined with persistent supply-side tightness, will support further expansion of capital investment across the industry ecosystem. Bank of America echoed a similarly constructive outlook on the sector.

The broader optical communications sector recovered in tandem, with Lumentum up nearly 2%, Corning up over 1.7%, and Applied Optoelectronics up over 2%. The Philadelphia Semiconductor Index also advanced, rising as much as 1.55%. As a core supplier of optical interconnect solutions for AI computing infrastructure, Coherent benefited from the institutional buy signals following its sharp prior-session decline.
