Shares of AI optics companies Applied Optoelectronics, Lumentum, and Coherent dropped 6-10% after months of strong gains driven by demand for high-speed data center components. The pullback reflects profit-taking by momentum traders as technical indicators showed overbought conditions. These companies benefit from the AI data center buildout, with rising revenues and significant investments like NVIDIA's stake in Coherent. Going forward, investors will watch upcoming earnings and hyperscaler spending for signs of sustained growth or further volatility.
