Investors on the hunt for under-the-radar ways to play the booming artificial intelligence theme may want to take a look at this Nvidia derivative play up nearly 60% this week. The company also shared above consensus third-quarter expectations and said it anticipates a recovery in bookings. While Craig-Hallum and Needham both said they believe Nvidia is the AI platform in question, Vicor CEO Patrizio Vinciarelli simply referred to the project as a "new generation" for an "existing customer" during an earnings call Tuesday. Needham also believes that the Vicor remarks may signal a relationship with Nvidia. It called company the "supplier of choice" for AI accelerator power management.
