13F Hedge Fund Holdings API — Quarterly Buys, Sells & Exits

Get any hedge fund's or institutional investor's full portfolio from SEC 13F filings — with tickers, portfolio weights and a NEW / ADDED / REDUCED / EXITED label on every position versus last quarter.

Every US manager with $100M+ in US equities must disclose their holdings each quarter in a 13F filing. The raw filings are XML tables keyed by CUSIP codes, split across sub-managers, in inconsistent units. This Actor turns them into a clean, ranked portfolio and tells you exactly what changed.

Built-in fund shortcuts

Type the name instead of looking up a CIK:

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

Any other manager: find their CIK at sec.gov/edgar/search and enter the number (e.g. 1067983).

const run = await client.actor('smartmoney-data/sec-13f-hedge-fund-tracker').call({ managers: ['Pershing Square'] });
const { items } = await client.dataset(run.defaultDatasetId).listItems();

FAQ

How current is 13F data? 13Fs are filed up to 45 days after each quarter end (mid-February, May, August, November) and show holdings as of the quarter end — not today.

Why don't I see a fund's short positions or cash? 13F rules only require long positions in US-listed equities, options and convertibles. Shorts, cash, bonds and non-US holdings aren't reported.

Why is ticker empty for some rows? A few securities (e.g. warrants, delisted or foreign-listed shares) have no US ticker mapping. The CUSIP and issuer name are always present.

A manager has thousands of positions — is that OK? Yes. Ticker lookup for very large portfolios is faster if you add a free OpenFIGI API key in the input.

Why does a row have a dataNote? Some managers file a 13F-NT notice instead of holdings when another entity reports for them. If a manager's newest quarter is only a notice, you get their latest self-reported quarter plus a dataNote explaining it, never silently stale data. Built-in shortcuts already follow funds that moved their filings to a new entity (e.g. Pershing Square).

What about amended filings? The original quarterly 13F-HR is used; amendments (13F-HR/A) are ignored for consistency.
