Vicor Corporation's stock plummeted 6.17% during intraday trading on Tuesday, extending a multi-session pullback as selling pressure intensified.

The decline comes after the company's strong FY26Q1 earnings report, which showed revenue and earnings per share exceeding market expectations, along with better-than-anticipated capacity expansion progress and the securing of Cerebras as a core incremental customer. These positive results had driven a single-day surge of over 13% on May 11, accumulating significant short-term gains. However, recent concentrated selling by company insiders, including Director Tuozzolo Claudio and other executives offloading shares near the $270 price level, and Director Schmidt James F selling 1,241 shares, has combined with short-term profit-taking to weigh on the stock across multiple consecutive sessions.

The broader Electrical Components & Equipment sector also traded lower during the session, contributing to the downward pressure on Vicor's stock price.
