Coherent Rises 5% as CoreWeave’s Beat-and-Raise Revives the AI Trade: “A Breakout Quarter”
Coherent (COHR) shares rose 5% after CoreWeave reported strong Q3 results and raised its 2026 outlook, benefiting other optics-related companies like Lumentum (LITE), Marvell (MRVL), Credo (CRDO), and Astera Labs (ALAB). CoreWeave's revenue surged 168% to $3.66B, with a $132.5B backlog. Coherent's demand is strong, but it burned cash last quarter. COHR trades below its 5-year avg. forward P/E, with its next earnings report on Feb. 3.
