George Chamoun

George Chamoun, listed as chief executive, appears in our data through filings on ACV Auctions Inc. shares, published by SEC (Form 4). In total, 69 filings cover trades dated from 21 April 2022 to 1 October 2026.

The open-market side counts 4 purchases for €531k alongside 5 sales for €5.4M. On balance, insiders were net sellers of €4.9M. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Outside the open market, there are 39 share grants and 6 option exercises. 2026 to date brings 3 purchases and no sales.

Half of the purchases are above €107k and half below. Of 4 purchases, 1 formed part of a group of insiders buying within 30 days of each other. Purchases made close together by different insiders form what is called a cluster. Looking at 4 purchases old enough to measure, the stock rose over the following 90 days in 25% of cases; the median change was -26.0%. They describe history only and say nothing certain about the share price ahead.

The latest filing, published on 5 October 2026, reports a share grant of €124k in ACV Auctions Inc. The last purchase on record was published on 11 March 2026, which is 221 days ago. Typically, a trade is published a median of 2 days after it takes place. US insiders must file a Form 4 within two business days of a trade. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
