Get alerted the next time HORIZON KINETICS ASSET MANAGEMENT LLC — or any insider — buys

We watch every Form 4 as it hits SEC EDGAR and alert you when insiders cluster into the same stock.

About this data

Figures are parsed from HORIZON KINETICS ASSET MANAGEMENT LLC's Form 4 filings on SEC EDGAR (CIK 1056823) and cover open-market purchases (transaction code P) — grants, option exercises, and sales are excluded, which is why totals here can differ from raw filing counts. Every row links to its source document.

This page is informational and reflects public filing data. It is not investment advice.
