How quickly were GSK trades reported?
Days from each trade to the date its periodic transaction report was filed.

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’ GSK trades after that date are not included until the Senate eFD import is live, so this page undercounts Senate activity since then (2 of the 53 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 GSK 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 GSK.
