On May 28, Vicor Corporation declined 5.32% in regular trading, trading at $330.74/share, with trading volume of $27.79 million. The stock retreated sharply following a sustained multi-session rally.

On the news front, Director D'Amico Andrew sold shares on May 26 at prices between $320 and $324 per share, continuing a pattern of insider selling that previously saw Director Tuozzolo Claudio reduce positions at approximately $270. The company had recently surged over 21% after raising its Q2 revenue guidance to $142 million, significantly above FactSet consensus of $125.5 million. The guidance increase was supported by a new patent licensing agreement and strong FY26 Q1 results that exceeded expectations on both revenue and EPS, with production capacity expansion progressing ahead of schedule and Cerebras secured as a key incremental customer.

With cumulative gains significantly extended following the guidance revision, concentrated profit-taking combined with continued executive selling created multiple headwinds, resulting in the current technical correction.
