Investor portfolios from SEC Form 13F
Every quarter, investment managers with more than 100 million dollars in US-listed equities report their positions to the SEC on Form 13F. autario reads the filings of 19 well-known investors and keeps their holdings, quarter-over-quarter moves and portfolio value as open datasets.
Form 13F is filed up to 45 days after the quarter ends, so these are positions as of the quarter end, not today. Form 13F shows long US-listed equity positions and options only: no shorts, no cash, no non-US listings.
