Data from 13F filings with the SEC. The 13F lists only US stocks held long: no short positions, foreign stocks not listed in the US or cash. It is filed up to 45 days after the quarter ends and some positions may stay confidential. Purchases and sales are estimates: the difference in shares between two quarters times the quarter-end price.
