Jacques Janssen, listed as chief executive, appears in our data through filings on ABEO shares, published by AMF. Between 8 October 2021 and 9 June 2026, the trades on record add up to 48 filings.

No open-market sale appears; the market trades are 48 purchases worth €4.0M. Unlike grants, an open-market purchase is paid for by the insider, at the market price. In 2026 alone, the filings show 3 purchases and no sales.

In size, the median ticket on the buying side is €2,768. Of 47 purchases, 43 formed part of a group of insiders buying within 30 days of each other. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase. For 47 purchases whose 90-day window has closed, the share price was higher on day 90 than the day after publication in 51% of cases, with a median move of +1.5%. These figures describe past trades and do not predict future prices.

The latest filing, published on 11 June 2026, reports an open-market purchase of €900k in ABEO. Filings reach the AMF feed a median of 2 days after the trade. Under the Market Abuse Regulation, managers have three business days to notify their trades. This summary is built from AMF disclosures alone and does not predict where the share price will go.
