About the data

Where it comes from

Congressional trades are STOCK Act periodic transaction reports filed with the House Clerk and the Senate, collected through Quiver Quantitative. Members must file within 45 days of a trade; amounts are reported in ranges, never exact figures.

Insider transactions are SEC Forms 4 and 5, filed by officers, directors and 10% owners within two business days of a trade, collected through Quiver Quantitative. Form 144 notices of intent to sell restricted stock come directly from SEC EDGAR.

Institutional holdings are SEC Form 13F quarterly reports from managers with over $100M under management, due 45 days after quarter end, collected through Quiver Quantitative. 13F covers long positions only.

Schedule 13D and 13G filings, made when a holder crosses 5% of a class, come directly from SEC EDGAR. Structured filings began on 18 December 2024; earlier filings are not included.

How the numbers are calculated

Politician dollar figures use the midpoint of the disclosed range. A trade reported as $15,001 to $50,000 counts as $32,500. Totals built from midpoints are estimates and are labelled as such. The trade-count view avoids this assumption entirely.

Insider flow counts open-market purchases (code P) as buying and open-market sales (code S) as selling, valued at the reported price. Awards, option exercises, tax withholding, gifts and other codes are shown but excluded from the flow, because they do not express a view on the stock.

Institutional flow is the quarter-over-quarter change in shares held across all 13F filers, valued at the quarter-end price, and plotted at the quarter end. Because 13F is quarterly and lagged, the institutional series is coarse and late by design.

Stance labels compare net flow to gross activity over the window. A group is accumulating when net buying exceeds 20% of its gross activity, distributing when net selling does, and mixed otherwise. Groups with no activity get no label.

Limits worth knowing

• Filings are what people report, not what they did. Late, amended and missing filings exist, and this site reflects the record as filed.
• Tickers in disclosures are typed by filers. Companies that were renamed or delisted appear under the symbol used at the time.
• Insiders are matched by name until an SEC identifier is available, so two people with the same name at different companies can share a page.
• 13F data per company is capped by the provider at the most recent quarters for very widely held stocks; history deepens as new quarters arrive.
