Coherent is trading 7.3% up at $242.53, apparently as AI-infrastructure sentiment rebounds and optical stocks strengthen.
- Reports say the optical group gained after Lumentum’s CEO described component capacity as sold out through early 2029, pointing to demand that may benefit suppliers such as Coherent.
- Coherent shares closed at $231.80 on October 20 after a sharp pullback earlier in the week. No fresh company-specific catalyst was identified for October 21; the rally is consistent with improved sector sentiment.
