A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. The filings include the largest sale, €2.0M, on 7 November 2025.

The last insider purchase was made public on 9 October 2026, 15 days ago. Between a trade and the moment it shows up on CVM (Brazil), the median delay is 29 days. That lag is the time during which only the insider knows about the trade. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification.
