Transactions

Independent third-party platform; not affiliated with or endorsed by any member of Congress. Data sourced from publicly available filings and records. Portfolio, holdings, returns, and allocations are estimates and may differ from actual values. Informational and educational only; not investment advice. Shares, prices and post-transaction holdings are exactly as reported on SEC Form 4; the whale score is a model ranking of that filed activity.
