On September 16, Coherent rose 3.02% in pre-market trading, trading at approximately 279.06 USD/share, with turnover of 4.11 million USD. The rebound follows a sharp 12.73% single-day plunge in the prior session, when three major AI leaders publicly called for slowing AI development, triggering a broad selloff across optical communication and semiconductor names.

On the news front, Citi released a research note arguing that the recent semiconductor pullback presents a rare buying opportunity, stating that market fears over AI spending deceleration are significantly overdone. Citi highlighted 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 the bullish stance on the semiconductor and optical communication sectors. The broader optical communication segment rallied in sympathy, with Lumentum up 1.92%, Corning up 1.71%, and Applied Optoelectronics up 2.34% in pre-market trading.

Coherent is a global leader in materials, networking, and lasers, serving as a core supplier of optical interconnect solutions for AI computing infrastructure. The Philadelphia Semiconductor Index had already rebounded 1.40% in the prior regular session, with Coherent gaining 3.81% during that recovery.
