In open-market terms, that means 2 purchases worth €114k on one side and 11 sales worth €110k on the other. The amount is not disclosed for 2 filings. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Besides market trades, the filings include 5 share grants and 1 option exercise. In 2026 alone, the filings show no purchases and 7 sales.
The newest entry dates from 23 September 2026: an open-market sale of €3,403, in Quantum-Si Inc. The most recent open-market purchase was published on 13 August 2024, 796 days ago. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. Section 16 rules allow two business days to file each Form 4. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
