Vicor's stock soared 5.06% in pre-market trading, continuing its recent volatile price action.

The company's FY26Q1 earnings, released in April, showed both revenue and earnings per share exceeding market expectations. Furthermore, Vicor secured Cerebras as a core incremental customer, reinforcing its growth trajectory in high-performance power delivery for AI computing applications.

However, the stock faces insider selling pressure, with multiple executives, including Director McNamara Michael, selling shares in recent sessions, which may contribute to heightened short-term volatility.
