Why is Coherent Corp. (COHR) stock moving?

Coherent reported fiscal Q1 2027 revenue of $2.37B and a 40.6% non-GAAP gross margin. It guided Q2 to a midpoint of $2.65B revenue and $2.38 EPS, and raised its FY27 growth outlook above 60%. It also cited a $20B long-term agreement and 85% Data Center growth. The stock still fell 12.98% on Nov 5 to $169.76, an intraday low of $160.23, on volume of 17.3M shares against a 7.9M average. The drop came amid a broad AI-optical selloff that also hit Lumentum and Applied Optoelectronics. Investors focused on heavy capacity spending, negative operating cash flow and valuation compression, and Stifel said operating leverage, not gross margin, drove the EPS beat. On Nov 6 the shares rebounded about 10-13% to roughly $186-$193. That recovers part of the loss but leaves them about 50% below the one-month-ago level and about 56% below the $440 high. Analyst sentiment stays constructive: the average target is about $388, Rosenblatt kept Buy at $400, and Northland upgraded. BofA and Riley hold Neutral with targets of $228-$240. With a beta above 2.2, swings are large and sector sentiment is the dominant driver. A rebound from a capitulation-style low on heavy volume supports a bounce, but the downtrend and the volatile sector keep conviction modest.
