Horizon Kinetics Asset Management LLC

Horizon Kinetics Asset Management LLC discloses dealings in 2 companies, chiefly Texas Pacific Land Corp and RENN Fund, Inc. Between 15 February 2023 and 29 September 2026, the trades on record add up to 563 filings.

Purchases make up the whole of the open-market record (563 purchases, €913k). The totals exclude 14 filings filed without an amount. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. In 2026 alone, the filings show 221 purchases and no sales.

The median purchase comes to €1,071. Measured against the company's value, the median purchase equals 0.0000% of market capitalisation, across 138 purchases where it is known. Clusters matter here: 174 out of 560 purchases overlapped with buying by a colleague within 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. For 245 purchases whose 90-day window has closed, the share price was higher on day 90 than the day after publication in 44% of cases, with a median move of -1.7%. This is a record of the past, not a forecast.

The latest filing, published on 1 October 2026, reports an open-market purchase of €1,199 in Texas Pacific Land Corp. The median gap between a trade and its publication by SEC (Form 4) is 1 day. 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.
