Jason Raleigh Nunn: trading record in brief

Jason Raleigh Nunn has filed trades across 3 companies (mainly through SEC (Form 4)), most often in Addex Therapeutics Ltd., Regulus Therapeutics Inc. and Zenas BioPharma, Inc. Between 16 September 2024 and 2 September 2026, the trades on record add up to 6 filings.

On the market, this insider has only ever bought: 1 purchase, €1.0M in total. 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 2 share grants.

The newest entry dates from 4 September 2026: a share grant, in Addex Therapeutics Ltd. The clock since the last published purchase (14 October 2025) now reads 369 days. 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. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
