How to read 13F data

A 13F filing lists the US-listed stocks, ETFs and some options a manager held at the end of a quarter. It is filed up to 45 days after the quarter ends, so positions may have changed since. It does not show short positions, bonds, cash, foreign-listed shares or private investments, so for many funds it is only part of the picture.
