Most "who owns this stock" pages show you the top 10 holders, a quarter late, behind a paywall. This Actor reads the SEC's own quarterly Form 13F data sets (every 13F filer, every position) and returns the full list of institutional holders for any US stock, with a clear label for each one: NEW, ADDED, REDUCED, UNCHANGED or EXITED versus the previous quarter.

What you can do with it

• 🏦 Full holder list: every fund that filed a 13F position in the stock, not just the top 10.
• 📈 Who is buying, who is selling: quarter-over-quarter share changes and the top buyers and sellers per stock.
• 🆕 Spot new money: funds that opened a position this quarter.
• 🚪 See who left: funds that sold their entire stake.
• 🔗 Pair with fund-level data: follow a single fund's whole portfolio with Hedge Fund 13F Tracker.

How to use it

Holders of a few stocks, with quarter-over-quarter changes

{ "tickers": ["AAPL", "NVDA", "TSLA"] }

Top 20 holders only, current quarter

{ "tickers": ["PLTR"], "maxHoldersPerTicker": 20, "compareWithPreviousQuarter": false }

A specific share class

{ "tickers": ["GOOG"], "cusips": ["GOOG=02079K107"] }

FAQ

Who has to file a 13F? Any institutional investment manager with $100 million or more in US-listed equities: hedge funds, mutual fund companies, banks, pensions and family offices.

Why is the data a quarter behind? Managers have 45 days after each quarter to file, and the SEC publishes the bulk data set after that. It is the same data every 13F site uses, straight from the source.

Are short positions included? No. 13F filings only cover long positions (plus put and call options, shown separately).

Is this legal to use? Yes. Form 13F filings are public records published by the SEC.
