About this data
- What is a 13F?
- A quarterly report to the SEC in which an investment manager with over $100 million in US-listed stocks lists what it holds.
- How current is it?
- Managers file up to 45 days after each quarter ends, so the holdings may have changed since.
- Whose figures are these?
- The values are as the manager reported them in the filing, not today's prices. The SEC lets a manager keep some positions confidential for a time, and those are not in the filing.
- What does it leave out?
- Short positions, cash, bonds and most holdings outside US markets. Options are left out here too.
