What am I looking at?

Every tracked SEC filing attributed to this investor or insider. Each timeline row is one transaction from an original filing — quarterly 13F position changes (new/add/trim/exit) for institutions, open-market Form 4 trades for individual insiders — and links to the source document on sec.gov. Position changes appear with the reporting lag the SEC allows: up to 45 days after quarter end for 13F, two business days for Form 4.
