See what hedge funds, banks and asset managers actually hold. Every manager with over $100 million in US equities has to report their positions to the SEC every quarter. This pulls those filings straight from EDGAR and compares them to the previous quarter, so you can see what was bought, sold and exited. Search by fund name, company name, or ticker symbol.
Any institutional investment manager with discretion over at least one hundred million dollars in qualifying US securities must file a Form 13F with the SEC every quarter. The filing lists their positions in those securities as of the final day of the quarter, with share counts and market values.
This is how the public gets to see what Berkshire Hathaway, Bridgewater, Renaissance and several thousand other managers were holding. It is genuinely useful information and it is completely free, which is why it attracts so much attention.
Managers have forty five days after quarter end to file. A 13F published in mid February describes positions as of December 31. By the time you read it, the data is six weeks old at minimum, and the position it describes may have been built three months before that.
For a long term holder like a pension fund this barely matters, the position will still be there. For a fund that trades actively it matters enormously, because the filing can describe something that has already been sold. A 13F is a photograph of a moment that has passed, not a view of what anyone holds today.
Treat the filing date and the reporting date as two different things, because they are, and the gap between them is where most misreadings happen.
This is the part that makes naive copying dangerous.
Short positions are not reported. A fund showing a large long position in a stock may be running it as one leg of a hedge, or against a short in a competitor. You see one side of a trade that may not be directional at all.
Non qualifying securities are excluded. Bonds, most derivatives, commodities, currencies and foreign listed equities do not appear. A macro fund's 13F can represent a small fraction of what it actually runs.
Confidential treatment exists. Managers can apply to the SEC to delay disclosure of specific positions while they build them. Those holdings are legally omitted and appear later, if at all.
There is no cost basis and no conviction weighting. You see what was held, not what was paid, and not how the manager sizes risk.
Used properly they answer different questions than most people ask of them. Rather than "what should I buy", they are useful for seeing which institutions have accumulated a position in a company you already follow, how concentrated a manager's book is, whether institutional ownership in a name is rising or falling across quarters, and which managers cluster in the same thesis.
The quarter over quarter change is almost always more informative than the snapshot. A new position, a doubling, or a complete exit tells you something. A static holding usually does not.
Search by manager name or CIK to pull their most recent filing, showing each position with share count, market value and portfolio weight. Pages are deep linkable by CIK, so a specific manager can be bookmarked or shared directly.
Data comes straight from SEC EDGAR, the same source the filings are published to, with no intermediary. Always check the reporting period shown against today's date before drawing any conclusion from it.
