Latest filing published 25 Sept 2026 for LANSON-BCC, €756. Read the official filing
Based on 129 purchases whose 90-day window has closed (published at least 91 days ago), the same population our ranking model reads.
Entry is the close on the day after publication, the first price a reader could act on. Prices in the listing currency. Past moves are not a forecast.
Bruno Paillard (chief executive) discloses dealings in Lanson-BCC to AMF. We count 136 filings; the first trade dates from 12 February 2021 and the latest from 24 September 2026.
Purchases make up the whole of the open-market record (133 purchases, €7.7M). Unlike grants, an open-market purchase is paid for by the insider, at the market price. So far in 2026, the count stands at 4 purchases and no sales.
Half of the purchases are above €3,278 and half below. Scaled by market value, the purchases weigh a median 0.0013% of market cap (sample: 4 purchases). Clusters matter here: 19 out of 132 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. For 129 purchases whose 90-day window has closed, the share price was higher on day 90 than the day after publication in 47% of cases, with a median move of -0.3%. These figures describe past trades and do not predict future prices.
On 25 September 2026 came the latest disclosure, an open-market purchase for €756 in Lanson-BCC. Between a trade and the moment it shows up on AMF, the median delay is 6 days. For comparison, MAR article 19 gives managers three business days to notify a trade. Every figure here comes from the filings published by AMF and describes the past, not future prices; it is not investment advice.
