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.

Days after the filing date count from the trade to the report; a highlighted figure is past the 45-day deadline.

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’ TSM trades after that date are not included until the Senate eFD import is live, so this page undercounts Senate activity since then (4 of the 96 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 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.

TSM Congress trades: questions answered from the filings

Which members of Congress have traded Taiwan Semiconductor Manufacturing (TSM) stock?

29 members of Congress disclosed 96 trades in TSM between Jan 27, 2015 and Sep 22, 2026. The most active were Josh Gottheimer (D-NJ-05, 16 trades), Cleo Fields (D-LA-06, 12 trades) and Lisa McClain (R-MI-09, 11 trades). Senate trades after Nov 30, 2020 are not in these records yet.

Are members of Congress buying or selling TSM?

Across every disclosed trade, 47 were purchases and 49 were full or partial sales. In the 12 months since Oct 22, 2025, 5 members disclosed 14 purchases and 3 sales.

Who was the latest member of Congress to trade TSM?

Gil Cisneros (D-CA-31) disclosed a purchase of $1k – $15k dated Sep 22, 2026, reported on Oct 12, 2026 (20 days later). The earliest TSM trade in these records is Tom MacArthur's sale on Jan 27, 2015.

How much TSM stock have members of Congress bought and sold?

Periodic transaction reports give an amount band, not an exact value. Taking the midpoint of each band, disclosed purchases add up to about $2.0M and sales to about $1.0M; this is an estimate. The largest single disclosed trade was Cleo Fields's purchase of $250k – $500k on Aug 13, 2025.

How long did members of Congress take to report TSM trades?

Of the 92 TSM trades matched to a filing date, the median was reported 31 days after the trade and 90% within 280 days. 21 were filed after the STOCK Act's 45-day deadline, the longest 520 days after the trade.

Do Democrats or Republicans trade TSM more?

15 Democrats disclosed 58 TSM trades and 14 Republicans disclosed 38 trades. Democrats account for more of the trades.
