No open-market sale appears; the market trades are 15 purchases worth €373k. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Outside the open market, there are 12 share grants.

In size, the median ticket on the buying side is €24k. 7 out of 13 purchases came within 30 days of a purchase by at least one other insider of the same company. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

The latest filing, published on 2 January 2025, reports a share grant of €7,494 in Middlefield Banc Corp. The latest purchase dates back some time: it was published 1,908 days ago, on 19 August 2021. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. US insiders must file a Form 4 within two business days of a trade. Source: insider filings from SEC (Form 4).
