Happy David Walters: trading record in brief
Filings by Happy David Walters span 2 companies, the busiest being LifeMD, Inc. and Hyperion Defi, Inc. The record holds 47 filings, for trades running from 25 July 2019 to 17 December 2025.
Purchases make up the whole of the open-market record (42 purchases, €599k). 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 3 share grants. 2025 to date brings 1 purchase and no sales.
A typical purchase (the median) is worth €1,730. Clusters matter here: 28 out of 42 purchases overlapped with buying by a colleague within 30 days. Purchases made close together by different insiders form what is called a cluster.
The latest filing, published on 19 December 2025, reports an open-market purchase of €159k in Hyperion Defi, Inc. The median gap between a trade and its publication by SEC (Form 4) is 2 days. For comparison, the SEC allows two business days to file a Form 4. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
