Hedge Funds
Four times a year the largest and best-known US managers must file a Form 13F with the SEC: the US-listed securities they held on the last day of the quarter. It is a holding, not a trade: the form says what was held, never what was bought or sold, or on which day. And it is at least 45 days old the moment it becomes public, because a manager may file up to 45 days after the quarter closes. Not all of these managers are hedge funds — the list also holds a holding company, a foundation and family offices.
What the form leaves out
There are no short positions on it. The SEC instructs filers not to include them, so a manager who is long 100 shares and short 90 reports 100 long. Cash is not on it either, and neither is anything that does not trade on a US exchange: a European company appears only through its US listing or its ADR.
Puts and calls are counted nowhere on these pages. They are on the form, but they are shown in their own block on a manager’s page and never added to the share positions — a put is the opposite of a share position, and adding the two would produce a number that means neither.
A manager reports a CUSIP, not a ticker. The tables below name the issuer as the form spells it, which is why two share classes of one company can sit on two lines. Where this site does need a ticker — to measure what a share price did — the link from CUSIP to ticker comes from a reviewed file with evidence per line, and a position we could not map carries no figure rather than a guessed one.
This page is free to read, and it stops after 5 rows. Those are the 5 managers first on this alphabetical list, of the SEC filer identities we hold, out of 25. Reading the whole list, and the page behind every manager, is part of the subscription. So are the search box, the measured buy-following figures and the count of which securities several managers reported the same quarter. What that costs is on the pricing page.

What these figures are, and what they are not
Everything on this page is at least 45 days old. Form 13F describes the holdings on the last day of a quarter and may be filed up to 45 days after it. In our measurement of 230 filings the median delay was exactly 45 days, and 207 of them arrived between day 41 and day 45. A position shown here may since have changed or disappeared, and the form does not say when anything was traded.
These are facts from a public register: which securities a manager reported holding at the end of a quarter, and how that compares with what the same manager reported for the previous quarter. Nothing in these quarterly tables is a score.
The form contains no short positions — the SEC instructs filers: “You should not include short positions on Form 13F”, and a manager who is long 100 shares and short 90 reports 100 long. It contains no cash and no securities that do not trade on a US exchange: a European company appears only through its US listing or its ADR. The value shown is the market value on the last day of the quarter — not the price the manager paid for the shares.
Put and call lines are shown in their own block, never among the share positions. A put is the opposite of a share position and it is counted nowhere on these pages.
A manager may ask the SEC to keep certain positions out of the public filing for a time. Where that happened, the quarter says so — the absence of a position is then not a fact. A later filing that adds those positions is shown as what it is: an amendment, with its own date.
Quarterly holdings cannot be turned into a judgement of quality. The filings contain positions, not results: no purchase prices, no short book, no cash, and a book that may already have changed on the day it became public. So this section says what was reported, and nothing about how it turned out. Where this site does measure what happened next, it does so from share prices and says so in that block, never from the filings themselves.
