What do these figures leave out, and where are they from?Limits and source

What this number cannot tell you

  • A manager reports the value of its holdings on the last day of a quarter, within 45 days after it. A report that the manager amended is shown with the amendments applied.
  • Values are as filed, in dollars. A manager that files a combination report includes the holdings of the managers it names, so the same holding can be in two reports.
  • Only holdings that Form 13F covers are reported: US exchange-traded stocks and some funds, options and convertible bonds. Cash, most bonds and holdings abroad are not in a report.
  • The table lists a position once for each security, class, and put or call: the lines of the manager's table are summed. A line for a put or call states the value of the shares the option covers, not what the option costs or is worth.
  • A share is the value of a position as a part of the value of all the lines of the manager's table.
  • Where a name as filed includes the trademarked name of a stock index, the page shows [index name] in its place.
  • A position is new when the manager's table for the quarter before has no line for the security, and sold out when its table for this quarter has none. It says nothing about when a position was bought or sold: only the quarter ends are compared.
  • A manager can ask the SEC to keep some of its holdings confidential for a time; those holdings are missing from its report until it discloses them.
