Holly K. Koeppel: trading record in brief

Filings by Holly K. Koeppel span 5 companies, the busiest being American Electric Power Co Inc, Arch Resources, Inc. and Core Natural Resources, Inc. We count 53 filings; the first trade dates from 6 February 2006 and the latest from 28 May 2026.

Both buying and selling appear: 1 purchase worth €177k, against 32 sales worth €3.6M. Netting one side against the other leaves €3.4M of net selling. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. The rest of the record consists of 9 share grants and 8 option exercises. 2026 to date brings no purchases and 1 sale.

The latest filing, published on 29 May 2026, reports an open-market sale of €11k in Flutter Entertainment plc. The last insider purchase was made public on 1 August 2019, 2,641 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. The legal deadline for a Form 4 is two business days after the transaction. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
