COHH is trading at $5.34, up 5.74% on September 16, 2026, as beaten-down AI-photonics and optical-communications stocks rebound after Coherent’s recent selloff.
- Coherent, Lumentum, Applied Optoelectronics and related photonics shares are rising together, signaling sector rotation, not a company-specific catalyst.
- Broader equities are modestly higher, but stronger retail sales and elevated Treasury yields ahead of the Federal Reserve decision may limit rate-sensitive growth stocks.
- The primary driver remains the AI-infrastructure photonics rebound.
