Explore the portfolios of famous investors through SEC 13F filings. See what Warren Buffett, Ray Dalio, Michael Burry, and other legendary investors are holding.
Form 13F is a quarterly report that institutional investors managing more than 100 million dollars in U.S. equities must file with the Securities and Exchange Commission. Because of that requirement, anyone can see for free what investors such as Warren Buffett, Ray Dalio and Michael Burry hold. This page organises those filings to show each investor's positions and how they changed against the previous quarter. The strength of the data is that filing is a legal obligation, so these are confirmed holdings rather than rumour or inference.
You can track, quarter by quarter, which sectors a manager is leaning into, what they opened for the first time and what they exited entirely. When several well-known investors add the same name in the same quarter, that is a reasonable prompt to look into it. What the filing never contains is why, so the reasoning is something you have to research separately. The same position can mean very different things depending on how large a share of the portfolio it represents, so read weights alongside dollar amounts.
The most important limitation is the lag. A 13F is due within 45 days of quarter end, so by the time you read it the trade is anywhere from a few weeks to more than four months old, and the position may already have been sold in full. The scope is limited to long positions in U.S.-listed equities, so short positions, bonds, cash, foreign listings and private holdings never appear. A position taken as one leg of a hedge can therefore look like an outright directional bet with the hedge invisible. Using these filings as a reference is reasonable; replicating the published list as a portfolio is not, for exactly these reasons.
