Tammy Duckworth’s disclosed stock trades — and what copying them returned

What copying every disclosed buy would have returned

Our engine bought at the first opening price after each of Tammy Duckworth’s disclosed purchases became public, held until the matching sale was disclosed, and marked the book against simply holding the S&P 500 over the same window (Feb 6, 2013 – Aug 11, 2026). Fees on, position sizes equal — a filing never discloses the real amount, only a band.

Read the fill count before the return: a figure built on a handful of copied positions is an anecdote, whatever it says. And a copy-return is not Tammy Duckworth’s own return — the disclosure lag means a copier never got their entry price.

See plans All members and how the ranking works

Entries are at the first open AFTER the disclosure date — the earliest any copier could act. The member's own entry was up to 45 days earlier. Disclosed amounts are bands, not sizes; every position is sized at your chosen % of portfolio, which is not how the member sized it. Option purchases are copied as the underlying shares. A filing discloses no strike and no expiry, so an option cannot be mirrored — buying the stock is the closest a reader could get. It is 1.6% of all disclosed buys, but for some members it is a quarter to a half of everything they file, so their figure describes copying the filing rather than what the position itself did. Dividends are treated as reinvested (adjusted closes). Fees and taxes are not modeled. Positions are sized from equity at the time of each entry, so gains compound into later position sizes and most of the account sits in cash between filings. Read the drawdown next to the exposure figures: a portfolio that is mostly cash shows a small whole-portfolio drawdown even when its holdings fell hard. Absolute returns are model outputs, not achievable returns. Past disclosures are no promise of future filings — members stop trading, leave office, or file late in batches.
