Yes, 13F filings are public — every quarter, institutional investment managers with over $100 million in assets are required to disclose their U.S. equity holdings to the SEC, and those filings become a goldmine for anyone curious about where the smart money is moving. Below is a ranked look at the largest dollar-value position increases disclosed for the quarter ending 2026-03-31, based on real Form 13F data. Remember, a 13F is a snapshot of holdings at quarter-end, not a record of exact trade dates, so these figures reflect the change between filings rather than a single transaction.

These filings offer a window into institutional positioning rather than a play-by-play of trading strategy — the kind of detail investors often look for when they search for things like Michael Burry’s stock recommendations or wonder whether you can sell a hedge fund stake outright. As always, 13F data is backward-looking and shouldn’t be read as a signal to act on any single name mentioned here.
