Robert F. Williamson III: trading record in brief
Robert F. Williamson III has filed trades across 2 companies (mainly through SEC (Form 4)), most often in Perspective Therapeutics, Inc. and Pharmasset Inc. In total, 34 filings cover trades dated from 24 September 2008 to 12 November 2025.
The open-market side counts 25 purchases for €455k alongside 1 sale for €2.3M. The net balance comes to €1.8M 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. Other entries cover 6 share grants and 1 option exercise. 2025 to date brings 3 purchases and no sales.
A typical purchase (the median) is worth €13k. Of 25 purchases, 22 formed part of a group of insiders buying within 30 days of each other. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.
The newest entry dates from 14 November 2025: an open-market purchase of €17k, in Perspective Therapeutics, Inc. Typically, a trade is published a median of 2 days after it takes place. Section 16 rules allow two business days to file each 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.
