Columns are written from public disclosures: House and Senate periodic transaction reports, SEC Form 4, Japan’s EDINET large-holding reports and Taiwan’s insider registers and market data (TWSE, TPEx, MOPS and the central bank, with history from FinMind). Stock pages add SEC 13F fund holdings and company financials, analysts’ figures from Financial Modeling Prep and Finnhub, and lobbying and federal contract records from the Senate and USAspending.gov. Amounts are disclosed as ranges, so the figures are estimates. Nothing here is investment advice.
