What we track
Net Worth Index tracks publicly disclosed securities transactions by members of Congress and other public officials where source data is available. We focus on trade date, filed date, asset name, ticker, transaction type, ownership label, and reported value range.
How the data is sourced
Our system ingests recent public disclosure data from source-linked feeds and pages, converts those records into structured rows, and stores the resulting trade entries in a normalized format. When the same transaction appears multiple times during repeated source fetches, the importer applies a trade signature check so only one canonical record is published.
Trade date versus filed date
The trade date is when the transaction occurred. The filed date is when the public disclosure surfaced in the source material. We show both dates separately because a delayed disclosure can affect how readers interpret the significance of a trade.
Dollar values and limitations
Most disclosures do not provide exact values. They provide ranges. Net Worth Index preserves those ranges rather than inventing precision that the filing does not support.
Corrections and updates
If a source changes, if a disclosure is amended, or if a parsing issue is corrected, we update the corresponding record and preserve the newest reliable version.
What we do not claim
Net Worth Index does not claim that a trade is illegal, improper, or evidence of intent. We organize public records and give users a clearer interface for reviewing them.
