Allison Nagelberg: trading record in brief
Allison Nagelberg is a declared insider of Horizon Kinetics Holding Corp, with filings sourced from SEC (Form 4). In total, 4 filings cover trades dated from 5 September 2024 to 18 September 2026.
Every open-market trade on record is a purchase: 4 purchases worth €15k, and no sale. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Since January 2026: 2 purchases and no sales on the market.
Half of the purchases are above €4,374 and half below. Of 4 purchases, 4 formed part of a group of insiders buying within 30 days of each other. Purchases made close together by different insiders form what is called a cluster.
Most recently, on 22 September 2026, the filings show an open-market purchase worth €4,347 in Horizon Kinetics Holding Corp. Filings reach the SEC (Form 4) feed a median of 4 days after the trade. 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.
