In size, the median ticket on the buying side is €52k. Of 6 purchases, 6 formed part of a group of insiders buying within 30 days of each other. Purchases made close together by different insiders form what is called a cluster. Looking at 13 purchases old enough to measure, the stock rose over the following 90 days in 46% of cases; the median change was -3.6%. Past outcomes like these are no guarantee of what comes next.

The newest entry dates from 11 June 2025: a share grant, in SM Energy Co. The last insider purchase was made public on 26 June 2020, 2,326 days ago. Typically, a trade is published a median of 2 days after it takes place. US insiders must file a Form 4 within two business days of a trade. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
