Purchases make up the whole of the open-market record (3 purchases, €208k). A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Outside the open market, there are 13 share grants.

The median purchase comes to €66k. Of 3 purchases, 3 formed part of a group of insiders buying within 30 days of each other. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.

The record was last updated on 12 May 2025 with a share grant in Boyd Gaming Corp. The most recent open-market purchase was published on 14 August 2023, 1,161 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 3 days. US insiders must file a Form 4 within two business days of a trade. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
