The open-market side counts 3 purchases for €49k alongside 4 sales for €3.6M. Netting one side against the other leaves €3.5M of net selling. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Outside the open market, there are 21 share grants.

A typical purchase (the median) is worth €16k. Clusters matter here: 3 out of 3 purchases overlapped with buying by a colleague within 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.

The record was last updated on 5 March 2025 with a share grant (€240k) in Green Brick Partners, Inc. The clock since the last published purchase (28 June 2018) now reads 3,056 days. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. 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. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
