A quarterly report filed with the SEC by institutional investment managers with $100 million or more in qualifying US securities. It lists their long positions at quarter end. It doesn't cover retail investors, cash, short positions, or managers under the threshold, so it shows part of a fund's ownership, not all of it.
How often is IOO ownership data updated?
13F filings are due 45 days after each quarter ends. The next set is due around mid-November. Positions can be up to about four and a half months old by the time a new set arrives.
