How to read this data
Delayed: 13F filings show holdings at quarter end and are filed up to 45 days later. Positions may have changed since.Incomplete: 13F covers only certain US securities (mainly listed shares and options) as long positions. Short sales, bonds, shares not listed in the US, over-the-counter derivatives and cash are not included.Options: for puts and calls, investors report the value of the underlying shares (notional), not the market value of the options. Puts can be a bet on falling prices or a hedge.Weights refer to the reported share positions (options excluded). Changes compare share counts with the prior quarter's filing.Not investment advice: this overview reproduces published filings. It is not an invitation to copy positions.
