How much of the picture this is

A 13F is a manager’s long US-listed equity book at a quarter end, filed up to 45 days later. Buyers and sellers count comparable managers (those that filed both quarters) by shares, so a rise in value with no rise in shares is the price. Large books are listed to their largest positions. These are 95 tracked managers, not the institutional market.
