What do these records cover?

House trades come from the official House Clerk filings from 2021 on; earlier House rows come from an archive of the same reports. Senate trades come from an archive that ends on Nov 30, 2020. Senators’ CDNS trades after that date are not included until the Senate eFD import is live, so this page undercounts Senate activity since then (0 of the 28 trades here are Senate filings). Scanned paper filings are not itemised, so their trades are not counted.

These are trades reported on periodic transaction reports, not current holdings: a member who bought CDNS may have sold it since, and a position bought before the records start, or held through a fund, does not show here. Amounts are disclosed as bands. This page is educational and is not a recommendation to buy or sell CDNS.
