On May 20, Vicor Corporation rose 6.38% in regular trading, trading at $256.5/share, with trading volume of $35.36 million. The stock staged a technical rebound following consecutive sessions of pullback.

On the news front, the company's FY26Q1 earnings report showed revenue and EPS both exceeding market expectations, with capacity expansion progress ahead of schedule and Cerebras secured as a core incremental customer. These catalysts drove a single-day surge of over 13% on May 11. However, the sharp short-term gains subsequently triggered sustained profit-taking, compounded by insider selling from directors including Tuozzolo Claudio at approximately $270 per share and Schmidt James F disposing of 1,241 shares. The combined internal selling pressure and short-term profit realization pushed the stock lower over multiple trading sessions. After several days of selling pressure dissipation and concentrated clearing of short-term positions, the stock exhibited a recovery bounce today.
