Every open-market trade on record is a purchase: 4 purchases worth €4.4M, and no sale. The totals exclude 1 filing filed without an amount. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. So far in 2026, the count stands at 1 purchase and no sales.
A typical purchase (the median) is worth €1.5M. Clusters matter here: 2 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.
