Susan B. Hirsch

Susan B. Hirsch is a declared insider at 2 companies (board member); the most frequent names are Agenus Inc and Tecogen Inc. We count 10 filings; the first trade dates from 1 July 2021 and the latest from 13 April 2026.

Purchases make up the whole of the open-market record (3 purchases, €42k). Unlike grants, an open-market purchase is paid for by the insider, at the market price. Other entries cover 7 share grants. Since January 2026: 2 purchases and no sales on the market.

Half of the purchases are above €16k and half below. Of 3 purchases, 3 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.

Most recently, on 14 April 2026, the filings show an open-market purchase worth €16k in Tecogen Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. For comparison, the SEC allows two business days to file a Form 4. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
