Dennis M. Fenton

Dennis M. Fenton has filed trades across 9 companies (mainly through SEC (Form 4)), most often in Amgen Inc, Xenoport Inc and Portola Pharmaceuticals Inc. The record holds 99 filings, for trades running from 24 February 2006 to 18 June 2025.

On the open market, the record shows 7 purchases worth €40k and 41 sales worth €9.9M. The net balance comes to €9.8M on the selling side. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Outside the open market, there are 15 share grants and 15 option exercises. In 2025 alone, the filings show no purchases and 1 sale.

A typical purchase (the median) is worth €1,731.

The latest filing, published on 20 June 2025, reports an open-market sale of €63k in Anaptysbio, Inc. The clock since the last published purchase (19 September 2017) now reads 3,337 days. Typically, a trade is published a median of 1 day after it takes place. Section 16 rules allow two business days to file each Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
