🐳 SEC Form 13F Holdings Tracker — Hedge fund quarterly positions — Berkshire, Bridgewater, Renaissance, Citadel

Track every Form 13F-HR filing — quarterly disclosures of institutional investment managers with $100M+ AUM, listing every U.S. equity position, share count, market value, and put/call holdings. Sourced directly from EDGAR. See what Berkshire, Bridgewater, Renaissance, Citadel, and 5,000+ other managers own at quarter-end.

One actor. One token. Real-time regulator-direct data delivered in structured JSON.

⚡ Popular Filers — Prefilled CIKs (no lookup required)

New in this build: pick a famous crossover or institutional fund from the popularFund dropdown and the actor will use the correct SEC CIK automatically. No need to dig through EDGAR. Pair the dropdown with a dateFrom / dateTo window covering a single quarterly filing deadline (mid-Feb, mid-May, mid-Aug, mid-Nov) to pull that fund's most recent holdings.

Fund	popularFund value	CIK	Last 13F-HR filed	AUM proxy (latest 13F aggregate value)
Tiger Global Management LLC	tiger-global	0001167483	2026-05-15	~$25B (long U.S. equity 13F book)
Coatue Management LLC	coatue	0001135730	2026-05-15	~$22B
D1 Capital Partners L.P.	d1-capital	0001747057	2026-05-15	~$11B
Whale Rock Capital Management LLC	whale-rock	0001387322	2026-05-15	~$8B
Lone Pine Capital LLC	lone-pine	0001061165	2026-05-15	~$15B
Viking Global Investors LP	viking-global	0001103804	2026-05-15	~$30B
Light Street Capital Management LLC	light-street	0001569049	2026-05-15	~$2B
Maverick Capital Ltd	maverick	0000934639	2026-05-15	~$7B
Citadel Advisors LLC	citadel	0001423053	2026-05-15	~$600B (multi-strategy, includes derivatives)
Two Sigma Investments LP	two-sigma	0001179392	2026-05-15	~$60B

All ten funds have filed 13F-HR within the last 4 quarters (Q2 2025 → Q1 2026). AUM proxies are computed from the aggregate value_usd in each fund's most recent 13F infotable and are intended as relative scale indicators, not official AUM figures.

Popular-filer use cases

• Track Tiger Global's quarterly moves — set popularFund=tiger-global, run after every May/Aug/Nov/Feb filing deadline, diff against the prior quarter's dataset.
• Monitor crossover fund concentration — run all ten dropdown values in batch, aggregate by cusip, find the names where 4+ crossover funds hold ≥1% positions.
• Citadel options scrape — Citadel files thousands of put/call positions per quarter; set popularFund=citadel + maxHoldingsPerFiling=0 to get the full options book.
• Quant overlay (Two Sigma) — pull Two Sigma's long equity book and join against your factor model to see which factors they're tilted to.
• Replicate a tiger cub portfolio — Coatue, Lone Pine, Maverick, Tiger Global, Viking, Whale Rock, D1, Light Street are all Tiger Management alumni or descendant funds. Pull all eight, take the intersection by cusip.
• Crossover crowdedness signal — count distinct popular-fund holders per name; flag the top decile as "crowded crossover" exposures.

When popularFund is set to anything other than none, the user-supplied filerCik is ignored. Power users who want a custom CIK should leave popularFund=none and fill in filerCik directly.

Cross-link to the rest of the sec-form-13f-tracker-pro use cases below — the popular-filer presets are a convenience layer on top of the full 13F coverage; everything in the use-case list below still works with popularFund=none.

Why This Actor Beats WhaleWisdom, Bloomberg Terminal, FactSet

• Per-row pricing vs. seat-based: WhaleWisdom Premium is $599/year for limited 13F coverage. Bloomberg's 13F screens require a $24K seat. We charge $0.005 per holding row — a complete Berkshire 13F (50 positions) costs $0.25.
• Raw EDGAR, no editorial layer: We give you the filed XML data. No interpretation, no estimated values, no "top picks" curation. You build the analytics.
• Manager + holding cross-reference: Cross-reference holdings by manager (what does Bridgewater own?) or by security (which managers own AAPL?) — the join is your join.
• Quarterly delta computation: Pair this with our 13f-holdings-delta-tracker to compute position changes quarter-over-quarter — the actionable signal.

Quick Start

Install the Apify Python client, set your token, and call the actor. The example below uses the new popularFund preset to pull Tiger Global's latest holdings without needing to look up the CIK:

from apify_client import ApifyClient

client = ApifyClient("YOUR_APIFY_TOKEN")

run = client.actor("nexgendata/sec-form-13f-tracker-pro").call(run_input={
    "popularFund": "tiger-global",
    "dateFrom": "2026-05-01",
    "dateTo": "2026-05-31",
    "maxFilings": 1,
    "maxHoldingsPerFiling": 25,
})

for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item)

You can also trigger via cURL:

curl -X POST "https://api.apify.com/v2/acts/nexgendata~sec-form-13f-tracker-pro/run-sync-get-dataset-items?token=YOUR_APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"popularFund": "coatue", "dateFrom": "2026-05-01", "dateTo": "2026-05-31", "maxFilings": 1}'

Schedule it on Apify's built-in scheduler for daily, hourly, or every-5-minute refreshes — no infra required.

FAQ

Q: When are 13F filings due?

A: Within 45 days after each calendar quarter end. February 14, May 15, August 14, November 14 are the deadlines.

Q: Why don't I see short positions?

A: 13F-HR discloses long equity positions and put/call options only. Short positions are not required to be filed.

Q: Are amendments captured?

A: Yes. 13F-HR/A amendments are flagged and reference the original filing's accession number.

Q: Can I get historical filings?

A: Yes. EDGAR 13F archive starts in 1999. Pass a date range or specific manager CIK.

Q: How accurate are the tickers?

A: We map CUSIPs to tickers using a maintained CUSIP→ticker table. Coverage is >99% for current names; older delisted securities may not have a ticker.

Q: Does this include 13F-NT (notice) filings?

A: Yes — notice filings tell you a manager filed under a different identifier (e.g. parent company). We surface the reference for completeness.

Q: How do I get a fund that isn't in the popularFund dropdown?

A: Set popularFund=none and fill in filerCik with the 10-digit zero-padded CIK from https://www.sec.gov/cgi-bin/browse-edgar?action=getcompany. Or leave both blank to scan all 13F-HR filings in the date range.
