Every open-market trade on record is a purchase: 9 purchases worth €76k, and no sale.

So far in 2026, the count stands at 4 purchases and no sales.

In size, the median ticket on the buying side is €8,063. Clusters matter here: 4 out of 8 purchases overlapped with buying by a colleague within 30 days. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time. Ninety days after publication, 7 purchases show a median change of +3.5%, with the price up in 57% of them. Past outcomes like these are no guarantee of what comes next.

On 5 October 2026 came the latest disclosure, an open-market purchase for €13k in Palisade Bio, Inc. Typically, a trade is published a median of 3 days after it takes place. Section 16 rules allow two business days to file each Form 4. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
