Purchases make up the whole of the open-market record (3 purchases, €47k). Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. In 2026 alone, the filings show 1 purchase and no sales.

In size, the median ticket on the buying side is €10k. Of 3 purchases, 1 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. For 3 purchases whose 90-day window has closed, the share price was higher on day 90 than the day after publication in 33% of cases, with a median move of -7.8%. These figures describe past trades and do not predict future prices.

Most recently, on 19 February 2026, the filings show an open-market purchase worth €7,644 in Sintx Technologies, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 5 days. US insiders must file a Form 4 within two business days of a trade. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
