George Tsilis says investors should watch Supermicro (SMCI) carefully with "how quickly it's moving." The company's high-beta aspects make it a volatile trade for investors, seen in its rally higher today. George notes it can just as quickly sell off. He talks about how Supermicro signals a resurgence of A.I. risk-taking and how it's "moving in sympathy" with Nvidia (NVDA).
