AUM figures shown are calculated by summing the reported market value of all positions in SEC 13F-HR filings — not the fund's actual assets under management.
- Excludes cash, bonds, private equity, short positions, and foreign-listed stocks not required to be reported.
- For PUT and CALL options, the reported Value is the notional value of the underlying shares — not the option premium paid. This significantly overstates the actual capital at risk.
- Actual fund AUM is typically higher and includes strategies, instruments, and positions that never appear in a 13F.
- 13F filings cover institutional managers with ≥$100M in 13F securities. Positions reflect end-of-quarter holdings, disclosed up to 45 days after the period ends.
