David Z. Hirsh: trading record in brief

David Z. Hirsh has filed trades across 2 companies (mainly through SEC (Form 4)), most often in Seaport Entertainment Group Inc. and Comstock Holding Companies, Inc. In total, 9 filings cover trades dated from 18 October 2024 to 15 September 2026.

Every open-market trade on record is a purchase: 1 purchase worth €9,663, and no sale. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Outside the open market, there are 8 share grants. Since January 2026: 1 purchase and no sales on the market.

Most recently, on 16 September 2026, the filings show a share grant in Seaport Entertainment Group Inc. The last insider purchase was made public on 27 August 2026, 58 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. Section 16 rules allow two business days to file each Form 4. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
