David F. Burgstahler

David F. Burgstahler is a declared insider at 6 companies; the most frequent names are Lantheus Holdings, Inc., Angiodynamics Inc and Syneos Health, Inc. We count 68 filings; the first trade dates from 27 July 2016 and the latest from 27 January 2023.

Market trades split into 3 purchases (€17.8M) and 48 sales (€237.1M). On balance, insiders were net sellers of €219.3M. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Besides market trades, the filings include 5 share grants.

A typical purchase (the median) is worth €5.6M. Clusters matter here: 2 out of 3 purchases overlapped with buying by a colleague within 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.

Most recently, on 30 January 2023, the filings show a transaction in RVL Pharmaceuticals plc. The latest purchase dates back some time: it was published 1,537 days ago, on 9 August 2022. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. For comparison, the SEC allows two business days to file a Form 4. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
