Both buying and selling appear: 15 purchases worth €3.3M, against 6 sales worth €6.2M. The net balance comes to €2.9M on the selling side. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Besides market trades, the filings include 67 share grants and 10 option exercises.

A typical purchase (the median) is worth €82k. Clusters matter here: 5 out of 15 purchases overlapped with buying by a colleague within 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

The record was last updated on 2 April 2026 with a share grant in Iridium Communications Inc. The last insider purchase was made public on 7 November 2023, 1,079 days ago. The median gap between a trade and its publication by SEC (Form 4) is 2 days. Section 16 rules allow two business days to file each Form 4. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
