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.

What You Get

Every record returned by this actor is structured JSON with the following fields populated wherever the source filing provides them:

• Manager name, CIK, filing date, period of report (quarter end)
• Manager AUM, total positions reported
• For each position: issuer name, CUSIP, share class, ticker (mapped)
• Position market value, share count, type (SH, PRN), put/call flag
• Investment discretion (sole, shared, none)
• Voting authority breakdown
• Accession number, EDGAR filing URL
• Amendment flag (13F-HR/A) and prior-filing reference
• Other manager flag (multi-manager structures)

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.
