Patrizio Vinciarelli, Chairman and CEO of Vicor Corporation (VICR), has been a consistent seller of company stock, with Form 4 filings showing 602 total transactions and zero open-market purchases. The aggregate sell value across his tenure stands at approximately $321.1 million, a figure that dwarfs any acquisition activity, which totals $0. This one-sided pattern is heavily weighted toward open-market sales (code "S"), which are the only transactions that reflect a discretionary decision to liquidate holdings.
The most recent cluster of filings, all occurring between July 1 and July 6, 2026, shows 25 separate sale transactions in VICR, ranging in value from roughly $33,800 to $1.3 million. The largest individual trades came on July 2, with two sales exceeding $1.24 million and $1.30 million, respectively, alongside several others in the $400,000–$640,000 range. The July 1 filings were similarly substantial, with the largest single transaction valued at approximately $716,600. Combined, these 25 recent sales represent a significant liquidation event, totaling over $8.5 million in just six days.
Notably, the filing history contains no recent purchases (code "P"), no option exercises (code "M"), and no grants or awards (code "A") in the recent window. The absence of any buy-side activity, combined with the high frequency and dollar volume of sales, paints a clear directional picture: Vinciarelli has been a net and persistent seller of VICR shares, with the pace accelerating in early July 2026. While the filings do not indicate motive, the transactional data alone shows a decisive and ongoing reduction of his stake in the company.
