No open-market sale appears; the market trades are 27 purchases worth €2.2M. 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 21 share grants and 6 option exercises.

The median purchase comes to €77k. Of 27 purchases, 7 formed part of a group of insiders buying within 30 days of each other. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

On 31 July 2026 came the latest disclosure, an option exercise in Cirrus Logic, Inc. The last insider purchase was made public on 21 November 2024, 701 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 1 day. US insiders must file a Form 4 within two business days of a trade. Source: insider filings from SEC (Form 4).
