The open-market side counts 46 purchases for €210.5M alongside 2 sales for €19.4M. Taken together, the purchases exceed the sales by €191.0M. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. In 2025 alone, the filings show 7 purchases and no sales.

A typical purchase (the median) is worth €95k. On 24 out of 44 purchases, another insider of the same company was buying within the same 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.

The latest filing, published on 22 July 2025, reports an open-market purchase of €25.7M in Believe. Filings reach the AMF feed a median of 5 days after the trade.
