CoreWeave Inc. received at least two analyst upgrades on Thursday after the cloud-computing company’s shares fell about 50% from their post-IPO high. H.C. Wainwright’s Kevin Dede raised his rating to Buy and set a $180 price target, citing what he called “strong fundamentals” and growing demand for the firm’s artificial-intelligence infrastructure services. Dede pointed to CoreWeave’s expanding partnership with chipmaker Nvidia and the company’s higher revenue guidance as key support for the more bullish view. The stock opened the session near $95, according to trading commentary, and options desks reported sizable January call-spread activity that would benefit from a rebound into year-end.
