Martin Edward Patterson: trading record in brief
Filings by Martin Edward Patterson span 3 companies, the busiest being Comscore, Inc., Liberty Broadband Corp and Charter Communications, Inc. /MO/. We count 19 filings; the first trade dates from 10 June 2021 and the latest from 19 August 2026.
On the market, this insider has only ever bought: 3 purchases, €13k in total. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Outside the open market, there are 5 share grants and 8 option exercises.
The median purchase comes to €4,794. Clusters matter here: 2 out of 3 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.
The record was last updated on 20 August 2026 with a transaction in Liberty Broadband Corp. The last insider purchase was made public on 21 June 2023, 1,236 days ago. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. US insiders must file a Form 4 within two business days of a trade. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
