Eugene Williams

Eugene Williams is a declared insider of ProMIS Neurosciences Inc., with filings sourced from SEC (Form 4). In total, 10 filings cover trades dated from 11 July 2022 to 5 March 2026.

Purchases make up the whole of the open-market record (10 purchases, €155k). Unlike grants, an open-market purchase is paid for by the insider, at the market price. Since January 2026: 4 purchases and no sales on the market.

A typical purchase (the median) is worth €7,717. 8 out of 10 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. Looking at 5 purchases old enough to measure, the stock rose over the following 90 days in 0% of cases; the median change was -12.7%. Past outcomes like these are no guarantee of what comes next.

The record was last updated on 6 March 2026 with an open-market purchase (€42k) in ProMIS Neurosciences Inc. Typically, a trade is published a median of 1 day after it takes place. The legal deadline for a Form 4 is two business days after the transaction. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
