Congress trades stocks.
We track every single one.
ChamberTrades collects, enriches, and publishes every stock trade disclosure filed by members of Congress under the STOCK Act — going back to 2012.
& House
What is the STOCK Act?
The Stop Trading on Congressional Knowledge Act (STOCK Act) was signed into law in 2012. It prohibits members of Congress from using non-public information gained through their official duties for personal financial gain — and requires them to publicly disclose stock trades within 45 days of the transaction.
Before the STOCK Act, members of Congress were largely exempt from insider trading laws that apply to ordinary citizens. Studies showed congressional portfolios outperforming the market at statistically significant rates.
The law created a public record — every purchase, sale, and exchange of stocks, bonds, and other securities must be filed with the Senate or House financial disclosure office. Those filings are public. We collect them.
How ChamberTrades Works
Collect
Our bot scrapes the Senate and House financial disclosure portals daily, collecting every new STOCK Act filing as soon as it appears.
Enrich
Each trade is enriched with real stock price data, sector and industry classification, committee assignments, and filing lag calculations.
Flag
We cross-reference every trade against the politician's committee assignments. A committee-sector overlap gets flagged — the strongest signal of potential informational advantage.
Score
Politician performance scores track win rate, average return, and alpha (return vs. the S&P 500) across 30, 60, and 90-day windows — so you know which politicians are worth following.
Publish
Everything is made available through ChamberTrades. Searchable, filterable, and updated daily. The same data Congress hoped you wouldn't look at.
⚠ Important Disclaimer
ChamberTrades is an informational tool. Nothing on this site is financial advice. We surface publicly available government disclosure data — we make no recommendations about whether to buy or sell any security. Past performance of any politician's trades does not guarantee future results. Always consult a qualified financial advisor before making investment decisions.
