Why Is Coherent (COHR) Stock Price Down 4.85% Today, August 24? Optical Selloff Pressures AI Networking Shares

Coherent shares fell ~4.9% amid a broader selloff across optical and AI-networking names, with peers also sharply lower and no verified company-specific negative disclosure. The move reads as sector-wide de-risking and positioning/valuation sensitivity in AI hardware rather than an operating reset. Near-term sentiment for optics-linked AI infrastructure is weaker, and price action underscores elevated volatility and correlation risk across the group.
