Purchases make up the whole of the open-market record (3 purchases, €411k). Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay.

Half of the purchases are above €67k and half below. Of 3 purchases, 1 formed part of a group of insiders buying within 30 days of each other. 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 13 November 2025: an open-market purchase of €67k, in Heidelberg Materials AG. Most trades are made public on the day they happen. Under the Market Abuse Regulation, managers have three business days to notify their trades. These figures are compiled from regulatory filings published by BaFin. They describe what insiders did and are not a recommendation.
