How quickly were TSM trades reported?
Days from each trade to the date its periodic transaction report was filed. The STOCK Act asks members to report a trade no later than 45 days after it happens; a later report is a matter of public record, not by itself evidence of wrongdoing. 4 trades could not be matched to a filing date and are not counted. Compare every member on the late-filing tracker.

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 the Senate eFD filings (10 of the 103 trades here). 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 TSM 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 TSM.
