Mark M. Gambill: trading record in brief
Filings by Mark M. Gambill span 3 companies, the busiest being Newmarket Corp, Speedway Motorsports LLC and Barings BDC, Inc. Over a trading history stretching from 20 April 2016 to 1 July 2025, the count stands at 19 filings.
The open-market record consists of 1 sale worth €207k, with no purchase. Outside the open market, there are 17 share grants.
The newest entry dates from 1 July 2025: a share grant, in Newmarket Corp. Typically, a trade is published a median of 1 day after it takes place. US insiders must file a Form 4 within two business days of a trade. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
