Filings by Margaret K. Dorman span 4 companies, the busiest being Smith International Inc, Range Resources Corp and Equitrans Midstream Corp. We count 56 filings; the first trade dates from 27 January 2006 and the latest from 14 May 2026.

The open-market side counts 6 purchases for €459k alongside 21 sales for €9.3M. Sales outweigh purchases by €8.8M. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Outside the open market, there are 19 share grants and 5 option exercises. 2026 to date brings no purchases and 2 sales.

A typical purchase (the median) is worth €74k. On 4 out of 5 purchases, another insider of the same company was buying within the same 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 15 May 2026 with a transaction (€187k) in Range Resources Corp. The latest purchase dates back some time: it was published 2,542 days ago, on 8 November 2019. 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. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
