Do Politicians Beat the Stock Market?

Some members of Congress are famous for stock trading headlines—but do politicians beat the stock market as a group? The honest answer from public disclosure data is not everyone, but a meaningful share does when you measure disclosed stock purchases against matched S&P 500 buys on the same dates.

The short answer

Using our latest rankings on disclosed stock purchases over the last 10 years (minimum five priced buys per member):

• 33 of the top 50 ranked members beat matched S&P 500 purchases on the same trade dates and amounts (beatSpyMultiplier above 1.0).
• 17 of those 50 did not beat the matched benchmark over the same window.
• 32 members currently appear on our politicians beating the market list, which filters to outperformers only.

So politicians do not universally beat the market—but a substantial minority of active traders with enough disclosed data has outperformed a matched SPY baseline, not a generic buy-and-hold line.

Who leads right now?

Among members with the strongest edge vs matched S&P 500 buys in our data:

Politician	Chamber	Disclosed return (10y window)	vs matched SPY
Brenda Lawrence	House	+1,187%	4.0× benchmark
Roger Marshall	House	+977%	3.4× benchmark
Rubén Hinojosa	House	+946%	2.7× benchmark
Barbara Comstock	House	+537%	2.0× benchmark
Ron Wyden	Senate	+468%	2.2× benchmark

These figures reflect reported stock purchases only, weighted by disclosed amount ranges—not a full net-worth portfolio or every asset class.

What this does—and does not—measure

What we include

• House PTR and Senate periodic transaction reports, plus executive-branch OGE filings where applicable.
• Returns on disclosed common-stock buys we can price, compared with matched S&P 500 purchases on the same dates.

What we exclude

• Trades filed late (see our late disclosures tracker).
• Assets reported only in broad value buckets without tickers.
• Exact share counts—filings use ranges (e.g. $15,001–$50,000), so returns are estimates.

That is why “beat the market” here means beat matched SPY on disclosed buys, not “every politician is a hedge-fund genius.”

A different question: timing the market

“Beating the market” can also mean picking unusually good days to trade—not how much purchases grew. That is a separate metric on Politician Stock Tracker.

Our do politicians time the market? ranking scores disclosed buys and sells against random dates on the same stock. The baseline is 50% — what you would expect from luck. Scores above 50% mean trades tended to land on better-than-random days (buys before rises, sells before falls), relative to comparable random timing.

247 members currently have enough scored trades for that list. Recent leaders include David Trone (80% timing score, 7 trades analysed) and John P Ricketts (71%, high confidence on 25 trades)—different names than the return leaderboard above. A politician can show strong returns without top timing, or the reverse.

Good timing does not prove insider knowledge; it is a statistical pattern in public filings only.
