Both buying and selling appear: 1 purchase worth €236k, against 10 sales worth €24.9M. Taken together, the sales exceed the purchases by €24.7M. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Outside the open market, there are 5 share grants and 11 option exercises. So far in 2026, the count stands at no purchases and 10 sales.

The newest entry dates from 4 September 2026: an option exercise of €486k, in Miami International Holdings, Inc. The latest purchase dates back some time: it was published 429 days ago, on 15 August 2025. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. For comparison, the SEC allows two business days to file a Form 4. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
