Market trades split into 16 purchases (€67.9M) and 14 sales (€306.5M). Taken together, the sales exceed the purchases by €238.6M. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Other entries cover 2 share grants and 1 option exercise. 2026 to date brings 1 purchase and 5 sales.
The median purchase comes to €2.1M. 7 out of 15 purchases came within 30 days of a purchase by at least one other insider of the same company. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.
The newest entry dates from 30 April 2026: an open-market sale of €20.0M, in Heartflow, Inc. The most recent open-market purchase was published on 20 April 2026, 187 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. Section 16 rules allow two business days to file each Form 4. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
