Bryan Giraudo

Bryan Giraudo is a declared insider at 2 companies (finance chief); the most frequent names are Gossamer Bio, Inc. and Protagonist Therapeutics, Inc. In total, 12 filings cover trades dated from 23 March 2022 to 2 January 2026.

On the open market, the record shows 5 purchases worth €357k and 2 sales worth €94k. Netting one side against the other leaves €263k of net buying. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Other entries cover 5 share grants.

Half of the purchases are above €55k and half below. 4 out of 5 purchases came within 30 days of a purchase by at least one other insider of the same company. Purchases made close together by different insiders form what is called a cluster.

The newest entry dates from 6 January 2026: a share grant, in Protagonist Therapeutics, Inc. The most recent open-market purchase was published on 20 June 2024, 850 days ago. Typically, a trade is published a median of 2 days after it takes place. For comparison, the SEC allows two business days to file a Form 4.
