Tamar Thompson

Filings by Tamar Thompson span 2 companies, the busiest being Catalyst Pharmaceuticals, Inc. and Avidity Biosciences, Inc. Over a trading history stretching from 7 October 2024 to 15 July 2026, the count stands at 7 filings.

None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.

Most recently, on 17 July 2026, the filings show a transaction worth €104k in Catalyst Pharmaceuticals, Inc. Typically, a trade is published a median of 2 days after it takes place. 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.
