Gene Boxer: trading record in brief
Gene Boxer discloses dealings in Costar Group, Inc. to SEC (Form 4). The record holds 12 filings, for trades running from 24 February 2023 to 15 March 2026.
None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.
The newest entry dates from 17 March 2026: a share grant of €16k, in Costar Group, Inc. Typically, a trade is published a median of 3 days after it takes place. For comparison, the SEC allows two business days to file a Form 4. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
