David J. Stetson

This profile gathers the share dealings of David J. Stetson across 2 companies, led by Alpha Metallurgical Resources, Inc. and Mallinckrodt plc. In total, 36 filings cover trades dated from 12 November 2018 to 31 July 2025.

Both buying and selling appear: 5 purchases worth €185k, against 8 sales worth €11.5M. On balance, insiders were net sellers of €11.3M. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Other entries cover 15 share grants and 2 option exercises.

The median purchase comes to €31k. Clusters matter here: 4 out of 5 purchases overlapped with buying by a colleague within 30 days. Purchases made close together by different insiders form what is called a cluster.

Most recently, on 4 August 2025, the filings show an option exercise in Mallinckrodt plc. The last purchase on record was published on 13 May 2021, which is 1,987 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. For comparison, the SEC allows two business days to file a Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
