Why Is Coherent Corp $COHR Stock Down -5.35% Today? (Find out why any stock moved today on Tickeron.) • Coherent Corp $COHR shares fell about 5.35% in Thursday's session, sliding from a prior close of $334.56 to roughly $316.67 intraday. • The decline was driven primarily by a broad sell-off across optical communications and AI-infrastructure stocks rather than company-specific news. • A report flagging a projected 32-gigawatt U.S. data-center power shortfall between 2026 and 2028 pressured expectations for optical-module supply-chain growth. • Profit-taking after a roughly 80%-plus year-to-date rally, alongside heavy bearish options activity and insider share sales, amplified the move. • The stock fell in line with peers and a modestly lower broad market, with traders now watching the company's next earnings report, expected around November 4, 2026. $MKSI $TDY $KRKNF $KEYS $VPG $CGNX $BMI
