Half of the purchases are above €43k and half below. On 16 out of 21 purchases, another insider of the same company was buying within the same 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase. Ninety days after publication, 19 purchases show a median change of -15.2%, with the price up in 26% of them. This is a record of the past, not a forecast.

The record was last updated on 22 June 2026 with a transaction in Serina Therapeutics, Inc. The latest purchase dates back some time: it was published 335 days ago, on 17 November 2025. 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. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
