No score on this page, by design. Everything here is a fact from a public U.S. register: insider filings at the SEC (Form 4), lobbying filings under the Lobbying Disclosure Act, trades reported by members of Congress under the STOCK Act, and fund holdings in 13F filings. Our scores, percentiles and signals run on the Dutch register only, because that is the only register the model has been validated on.
This page is free to read, and it stops after 5 rows. Those are the 5 most recent Form 4 lines at this company, out of 140.

Lobbying
From the quarterly LD-2 filings at the U.S. Senate — a different register, and a different kind of fact.
This is not a trade and it is not scored. A lobbying filing says who lobbied for whom, on which issues, and for how much — it says nothing about the share price and nothing about this company’s insiders. The link between the client names in that register and TAIWAN SEMICONDUCTOR MANUFACTURING CO LTD is a reviewed rule of ours: an LD-2 names a client and carries no ticker, no CIK and no LEI.
Lobbying reported per quarter
reported amounts per quarter, latest version of each report
Reported expenses: what this company reported spending on its own lobbying, per quarter, under the accounting method it picked itself.
Before 2025, these bars cover only the lobbying relationships that were still active in 2025 or later. Engagements that ended earlier are not included, so those years may be higher than shown.
