Open-market insider buying

Source: SEC EDGAR Form 4

Open-market purchases (SEC code P) disclosed on Form 4. Grants, option exercises, tax withholding and sales are excluded. Disclosed insider activity is not a prediction of performance.

U.S. House stock disclosures

Source: U.S. House of Representatives, Office of the Clerk (STOCK Act PTR disclosures)

STOCK Act Periodic Transaction Reports (House only). Disclosure can lag the trade by up to 45 days, amounts are broad ranges, and a trade may belong to a member, their spouse or a dependent. Not a buy/sell signal.

New SEC filings

Source: SEC EDGAR filings

Filing-change summaries
