Of 294 purchases, 21 formed part of a group of insiders buying within 30 days of each other. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time. Ninety days after publication, 290 purchases show a median change of -2.7%, with the price up in 36% of them. This is a record of the past, not a forecast.

Most recently, on 7 August 2026, the filings show an open-market purchase worth €636 in Les Constructeurs du Bois. Between a trade and the moment it shows up on AMF, the median delay is 2 days. The legal deadline for notifying a trade is three business days (MAR article 19). This summary is built from AMF disclosures alone and does not predict where the share price will go.
