The open-market side counts 8 purchases for €984k alongside 22 sales for €57.4M. On balance, insiders were net sellers of €56.4M. Unlike grants, an open-market purchase is paid for by the insider, at the market price. The rest of the record consists of 8 share grants. Since January 2026: no purchases and 12 sales on the market.

In size, the median ticket on the buying side is €85k. None of the 8 purchases we analysed coincided with buying by another insider of the same company within 30 days.

The record was last updated on 24 July 2026 with an open-market sale (€307k) in Butterfly Network, Inc. The last purchase on record was published on 30 November 2022, which is 1,418 days ago. Typically, a trade is published a median of 2 days after it takes place. For comparison, the SEC allows two business days to file a Form 4. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
