Do Congressional Stock Trades Beat the Market?
The honest answer is more nuanced than viral charts. Some lawmakers have strong-looking records, many do not, and the disclosure format makes precision difficult.
Why the question is hard
Public filings show ranges, not exact execution size. They also arrive after the trade date. That makes it hard to calculate true portfolio returns from filings alone.
A practical tracker can still compare disclosed purchases against a benchmark after the public filing or transaction date, as long as the methodology is clear.
What win rate means here
Congressional Trader's win-rate style metrics are designed to answer a narrower question: how often did tracked purchases outperform a benchmark over a chosen window?
That is useful for comparing patterns, but it is not the same as knowing a lawmaker's full investment return.
Better signals than raw returns
Trade count, filing speed, purchase versus sale mix, sector concentration, and committee relevance all help separate signal from noise. A high win rate based on two small trades is less persuasive than a solid record across many filings.

FAQ
Should I copy congressional trades?
No. The data is delayed and incomplete. It is better used for research, pattern detection, and monitoring than blind copying.
What benchmark should congressional trades be compared against?
A broad market proxy such as the S&P 500 is useful for context, but sector-specific comparisons can also matter for deeper research.
