About congressional stock trading

Quantellect tracks 212+ members of the U.S. Congress who disclose stock trades under the STOCK Act, totaling $2.247B across 35,311 trades in 3,203 companies. This page ranks every member by the BW Score, a 0–100 measure of the quality of their disclosed stock purchases, so you can see who has traded most successfully — not just most often. Select a time range to recalculate the leaderboard, search for a specific representative or senator, or open any member for their full congressional trading history.

What is the BW Score?

The BW Score rates a member of Congress from 0 to 100 on the performance of their disclosed stock purchases over a trailing 24-month window, marked to the latest closing price. It blends four factors: estimated profit, return versus the S&P 500, hit rate (the share of buys that are currently up), and how efficiently a member converts trading volume into gains. A member needs at least two priced disclosed buys in the window to receive a score, and thin track records are capped so a single lucky trade cannot top the leaderboard. Nancy Pelosi currently holds the #1 BW Score.

Frequently asked questions

Not investment advice. Congressional trading data is sourced from public STOCK Act disclosures, which are filed with a delay and may contain errors or be revised. Estimated prices and post-trade returns are derived algorithmically from public filings and end-of-day market data and describe historical activity, not a recommendation. Always do your own research and consult a licensed financial advisor before making investment decisions.
