What is a 13F filing and who has to file it?

It is a quarterly report to the SEC listing the US-listed stocks and certain other securities held by investment managers with at least $100 million in those securities. It shows long positions at the end of the quarter.

How delayed is 13F data?

Managers file up to 45 days after the quarter ends, so a 13F published in mid-November shows positions at the end of September. Positions may have changed since.

Does a 13F show a fund’s whole portfolio?

No. It leaves out short positions, most non-US securities, cash, bonds and most derivatives other than listed options, so it is a partial and delayed view.
