About fund managers and 13F portfolios
Quantellect lists the institutional managers that file a Form 13F with the SEC: about 8,736 hedge funds, asset managers, and superinvestors holding a combined $72.1T across 10,159 U.S.-listed companies as of Q2 2026. Search for a specific firm, or sort by assets under management or number of holdings to see the largest filers first, then open any manager to read their full portfolio and recent buys and sells. For the raw cross-fund holdings tape, see the Fund Activity page, and for trades by members of Congress see Congress stock trades.
How to read this page
Every manager here is a real 13F filer, and the figures come straight from their SEC filings. Assets under management is the market value of a manager’s disclosed U.S. stock positions at quarter-end, and the holdings count is how many separate positions they reported. Because managers file within 45 days of quarter-end, this is a quarterly snapshot of institutional positioning rather than a live view, and it covers long U.S.-listed positions only, not shorts, cash, or foreign shares. This is disclosed, historical activity, not a recommendation.
Frequently asked questions
How do I find a specific hedge fund or investor's holdings?
Type the fund or firm name into the search box above the table, for example Berkshire Hathaway or Scion Asset Management. Open any manager to see their full 13F portfolio: every U.S.-listed position, share count, value, and recent buys and sells.
Which famous investors and superinvestors can I follow here?
Well-known managers people track most, including Warren Buffett (Berkshire Hathaway), Bill Ackman (Pershing Square), and Michael Burry (Scion), often called superinvestors. To see what stocks Warren Buffett owns, open the Berkshire Hathaway profile for its current holdings and recent changes.
What is an institutional investment manager, or 13F filer?
Any firm or person that manages other people's money in U.S. stocks: a hedge fund, asset manager, bank, insurance company, or registered adviser. Once it controls $100 million or more in 13(f) securities, the SEC requires a Form 13F every quarter.
What does assets under management (AUM) mean on this page?
AUM here is the market value of a manager's reported U.S.-listed stock positions at quarter-end, taken from its 13F. It leaves out cash, bonds, shorts, and foreign shares, so read it as the disclosed long equity book, not the whole firm.
Why did a manager's AUM or number of holdings change from last quarter?
Two things move it: the manager buying or selling positions, and the stocks they already hold rising or falling in value. AUM can rise with no trades if existing holdings appreciated, and each profile shows the buys and sells behind the change.
Can I copy or clone a hedge fund's portfolio?
You can use a manager's holdings as research, and some investors mirror a filer's largest positions, an approach called cloning. Just remember 13Fs arrive up to 45 days late and never show shorts or hedges, so treat them as conviction, not a signal.
How many managers file 13Fs, and are they all listed here?
More than 5,000 managers cross the $100 million threshold and file a 13F each quarter, and this directory covers them, not a hand-picked subset. Firms holding less than $100 million in U.S. stocks are not required to file, so they will not appear.
How current is a manager's portfolio shown here?
It reflects their most recent 13F, filed within 45 days of quarter-end, so even the newest data is a look back at quarter-end rather than today. You can also open earlier quarters to see how a manager's positions changed over time.
Not investment advice. 13F data is sourced from public SEC filings, which are filed with a delay of up to 45 days and may be amended. Assets under management and holdings reflect positions reported at quarter-end and describe historical, disclosed activity, not a recommendation. Always do your own research and consult a licensed financial advisor before making investment decisions.
