Everything here is built by machine-reading the member's Periodic Transaction Reports on disclosures-clerk.house.gov and running our own code over them. The PDFs are often hand-filled or scanned and our parser can misread a ticker, date, amount or buy/sell; the reported dollar figures are wide bands, not exact sizes; there is up to a 45-day disclosure lag; positions opened before our price history, or sales filed late or never, skew the portfolio math; and the calculations themselves may have bugs. Treat the numbers as a rough guide and tell us if something looks off.
