On September 17, Coherent rose 3.07% in pre-market trading, trading at approximately $298.92/share, with turnover of $7.99 million.

On the news front, the Federal Reserve officially raised interest rates by 25 basis points, while the 10-year U.S. Treasury yield declined 5 basis points to 4.97%. The combination of the rate hike being fully priced in and easing pressure on discount rates lifted sentiment across high-valuation technology names. As a core supplier of optical interconnect solutions for AI computing infrastructure, Coherent had previously suffered a sharp 12.73% single-day drop on September 14 after major AI leaders called for slowing AI development, triggering broad-based selling across optical communication stocks. The stock subsequently entered a recovery phase, supported by bullish institutional signals from Citi and Bank of America, both of which flagged the semiconductor and optical sector pullback as an attractive buying opportunity, citing sustained AI inference demand growth and persistent supply-side tightness.

Within the Electronic Components sector, the broader group traded higher, with Corning up 3.0%, Vishay Intertechnology up 2.68%, and Amphenol up 2.25%.
