Methodology

Senate filings

Automated access to the Senate disclosure site stopped in October 2026. Senate periodic transaction reports disclosed from October 19, 2026, and older ones we never collected, come from Financial Modeling Prep’s feed rather than our reading of the original report; each still links to its Senate filing. Other Senate reports were read from the original documents.

Returns

We estimate stock portfolios from parsed disclosures and public equity prices. Amounts use range midpoints; “over $5 million” trades use $5 million. Returns compound daily, excluding cash contributions and holdings adjustments. Politicians rank by three-year return with at least 10 purchases and sales combined. The same politician, stock, date and transaction type count as one trade.

Stock rankings

Hottest Stocks and Biggest Selloffs score 90-day buying minus selling, weighted by politician rank and transaction age. Most Owned ranks estimated dollar holdings. Counts include unranked politicians.

Limits

Unparsed or unusable records are omitted; older prices may carry forward. Dividends are not added separately. Profiles show calculation dates and SPY comparisons (S&P 500 ETF). Estimates can change and are not verified brokerage returns.
