📊 SEC Form 13F Holdings Tracker — Hedge Fund Positions & Whale Watching

Track what hedge funds and institutional managers own. Pulls every position from a manager's SEC Form 13F-HR filing — issuer, CUSIP, market value, share count, position type, and voting authority — straight from SEC EDGAR. A free Quiver / WhaleWisdom / 13F.info alternative. No API key, no login, no rate-limit games. Built for quants, analysts, financial journalists, and AI agents.

⚡ What you get per holding

🎯 Use cases

• Whale-watching — mirror what Berkshire, Bridgewater, or any 13F filer bought and sold quarter over quarter.
• Quant signals — feed institutional position changes into factor models and backtests.
• M&A / activist research — spot accumulation and new positions early.
• Financial journalism — sourced, linkable position data for stories.
• AI agents — clean JSON over MCP for finance copilots.

🚀 Sample inputs

{"cik":"1067983","maxFilings":1,"minValueUsd":0}

{"cik":"1350694","maxFilings":4,"minValueUsd":10000000}

{"cik":"1423053","maxFilings":2,"minValueUsd":0}

cik = the manager's SEC Central Index Key (1067983 = Berkshire Hathaway). maxFilings = how many recent quarterly 13F filings to pull (1–12). minValueUsd = optionally skip positions below a dollar threshold.

📊 Sample Output

🛠 How it works

1. You supply a manager cik (look it up once on SEC EDGAR full-text search).
2. The actor queries data.sec.gov for that filer's most recent 13F-HR filings.
3. It parses the information-table XML for every holding.
4. Optional minValueUsd filter drops small positions.
5. Returns one clean JSON row per holding, each linked back to the source filing.

No scraping of paywalled aggregators — this reads the primary SEC source directly with a polite identified User-Agent.

⚖️ Legal & data sources

Data comes directly from the U.S. SEC EDGAR system (data.sec.gov and www.sec.gov/Archives), which is public-domain U.S. government data. Requests use an identified User-Agent per SEC's fair-access policy. This actor returns factual public filing data only — it is not investment advice.

❓ FAQ

How do I find a manager's CIK? Search the manager's name on SEC EDGAR full-text search (efts.sec.gov) or the EDGAR company search; the CIK is on their filing index page. How current is the data? 13F-HR filings are due 45 days after quarter-end; this returns them as soon as they're on EDGAR. Are dollar values in thousands? No — for filings since 2023 the SEC reports whole US dollars, and this actor returns whole dollars. Does it cover 13F-NT (notice) filings? It targets 13F-HR holdings reports, which contain the actual position tables. Can I pull many managers? Run once per CIK (e.g. via a loop in n8n/Make or an MCP agent); each run bills independently. Is there an API key? No — no login or key required. Does it work over MCP / for AI agents? Yes, it returns clean JSON suitable for agent tool-calls.

🆘 Troubleshooting

• No results returned — the CIK may not be a 13F filer, or has no 13F-HR in the requested window. Verify the CIK on EDGAR and increase maxFilings.
• Fewer holdings than expected — check minValueUsd; set it to 0 to include everything.
• Wrong manager — CIKs are filer-specific; confirm you used the institution's CIK, not a fund or person.
• Stale quarter — 13F filings lag ~45 days after quarter-end; the latest quarter may not be filed yet.
• Need the source — every row includes filingUrl linking back to the exact SEC filing.
