Teresa A. Harris

Teresa A. Harris (board member) discloses dealings in 2 companies, chiefly Altair Engineering Inc. and Ziff Davis, Inc. In total, 27 filings cover trades dated from 2 June 2021 to 7 May 2025.

On the open market, the record shows 3 purchases worth €110k and 4 sales worth €435k. Netting one side against the other leaves €325k of net selling. 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 4 share grants and 15 option exercises. Since January 2025: 1 purchase and 2 sales on the market.

The median purchase comes to €42k. Across 3 purchases, this insider has always bought alone, with no colleague buying within 30 days.

The record was last updated on 9 May 2025 with an option exercise (€101k) in Ziff Davis, Inc. The clock since the last published purchase (28 February 2025) now reads 597 days. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 1 day. For comparison, the SEC allows two business days to file a Form 4. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
