In open-market terms, that means 1 purchase worth €137k on one side and 2 sales worth €670k on the other. The net balance comes to €533k on the selling side. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. The rest of the record consists of 1 option exercise. In 2026 alone, the filings show no purchases and 2 sales.
On 15 September 2026 came the latest disclosure, an open-market sale for €201k in Oklo Inc. The most recent open-market purchase was published on 31 March 2025, 587 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 4 days. For comparison, the SEC allows two business days to file a Form 4. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
