Christian Jeanneau

Christian Jeanneau, listed as senior executive, appears in our data through filings on Assystem shares, published by AMF. In total, 8 filings cover trades dated from 2 August 2021 to 30 December 2025.

On the market, this insider has only ever bought: 6 purchases, €171k in total. Unlike grants, an open-market purchase is paid for by the insider, at the market price. The rest of the record consists of 2 share grants. So far in 2025, the count stands at 2 purchases and no sales.

A typical purchase (the median) is worth €24k. Clusters matter here: 1 out of 6 purchases overlapped with buying by a colleague within 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. For 6 purchases whose 90-day window has closed, the share price was higher on day 90 than the day after publication in 0% of cases, with a median move of -14.7%. Past outcomes like these are no guarantee of what comes next.

The latest filing, published on 31 December 2025, reports an open-market purchase of €1,066 in Assystem. Between a trade and the moment it shows up on AMF, the median delay is 4 days. The legal deadline for notifying a trade is three business days (MAR article 19). Every figure here comes from the filings published by AMF and describes the past, not future prices; it is not investment advice.
