Hedge Fund 13F Consensus - What Top Funds Buy Together

Not what one fund bought: what several of the best-known funds bought together. Cross-fund 13F consensus, straight from SEC EDGAR.

Illustrative rows; real runs return the full fields listed under Output.

One manager opening a position can be noise. Four of them opening it in the same quarter is a theme. This Actor loads the latest 13F filing of every fund you pick, compares each to its previous quarter, and returns one row per stock: how many funds hold it, who opened, added, trimmed or sold out, the combined value and change in shares, and who holds it at high conviction.

What you can do with it

• 🧮 Quarterly theme report: the stocks most top funds piled into, and the ones they all dumped.
• 🎯 Idea generation: new positions opened by 2+ value investors in the same quarter.
• 📰 Content: "What Buffett, Ackman and Burry agree on", ready-made every 13F season.
• 🤖 AI agents: "Which stocks did the most hedge funds buy last quarter?" as one tool call.

How it works

1. Lists each fund's 13F-HR filings and picks the newest quarter at least half of the funds have filed (or the period you set). Funds that haven't filed it yet are listed in SUMMARY.skippedManagers, not mixed in from another quarter.
2. Compares each fund's holdings with its previous quarter: NEW, ADDED, REDUCED, EXITED.
3. Aggregates by security (CUSIP). The consensus score is 2 × new + added − reduced − 2 × exited: opening and closing a whole position count double.
4. Looks up tickers for the rows returned (OpenFIGI, cached across runs).

Preset funds: Berkshire Hathaway, Bridgewater Associates, Renaissance Technologies, Pershing Square, Scion Asset Management, Soros Fund Management, Citadel Advisors, Duquesne Family Office, Third Point, Tiger Global Management, Baupost Group, ARK Investment Management, Appaloosa. Add any other filer by its SEC CIK.

FAQ

How current is 13F data? 13Fs are due 45 days after each quarter ends, so the latest quarter is 6 to 20 weeks old. It shows positioning, not today's trades. For real-time signals pair it with the Smart Money Confluence Score.

Why are put and call positions left out? A put is a bet against a stock, so counting it as a holder would be misleading. Set includeOptions: true to see them as separate rows.

A fund I added has no prior quarter. What happens? It counts as a holder but never as a buyer or seller, so its whole portfolio doesn't show up as NEW.

Why is ticker empty for some rows? Some CUSIPs (private shares, warrants, delisted securities) have no ticker in OpenFIGI. Name and CUSIP are always present.

Is this legal to use? Yes. 13F filings are public data published by the US Securities and Exchange Commission.
