No open-market sale appears; the market trades are 9 purchases worth €146k. 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 3 share grants. In 2026 alone, the filings show 2 purchases and no sales.
In size, the median ticket on the buying side is €3,854. 6 out of 9 purchases came within 30 days of a purchase by at least one other insider of the same company. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time.
The record was last updated on 20 August 2026 with an open-market purchase (€7,380) in Nocopi Technologies Inc. The median gap between a trade and its publication by SEC (Form 4) is 4 days.
