Brice Chambard

Brice Chambard, listed as chief executive, appears in our data through filings on OBIZ shares, published by AMF. Over a trading history stretching from 3 May 2022 to 7 April 2026, the count stands at 54 filings.

On the open market, the record shows 53 purchases worth €1.1M and 1 sale worth €1.7M. Taken together, the sales exceed the purchases by €658k. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Since January 2026: 1 purchase and no sales on the market.

The median purchase comes to €12k. Clusters matter here: 11 out of 53 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. Ninety days after publication, 53 purchases show a median change of -11.5%, with the price up in 43% of them. These figures describe past trades and do not predict future prices.

The record was last updated on 10 April 2026 with an open-market purchase (€1,868) in OBIZ. Typically, a trade is published a median of 2 days after it takes place. 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.
