How this service works
Hedge fund holdings check grounded in official SEC EDGAR 13F filings, fetched live: top long US-equity positions VERBATIM (issuer, value, shares), total book value, deterministic concentration figure, filing dates, and an honest read of what the book shape suggests — plus what 13F cannot tell you (performance, shorts, non-US). Name in, official filing out. For allocator and trading agents.
Output
Returns verbatim top long US-equity positions (issuer name, market value, share count) from the fund's most recent 13F filing, plus total portfolio book value, a deterministic concentration figure, filing and period-of-report dates, and an explicit note on what 13F data cannot reveal (performance, short positions, non-US holdings).
Example use cases
Verify hedge fund positions before allocation
“Before we commit capital to this fund, can you grab their most recent 13F from the SEC and show me what their top US equity holdings are? I need to see the actual positions, the total book value, and how concentrated their portfolio is.”
Track competitor holdings for market intelligence
“I want to understand what our competitors are betting on. Pull the latest 13F filing for Tiger Global Management and break down their biggest long positions in US stocks — let me know their total portfolio value too.”
Validate fund strategy alignment with disclosure
“This fund claims to focus on large-cap tech, so let me verify that with their actual SEC filing. Can you fetch their 13F and show me their top holdings, concentration metrics, and book value so I can see if their portfolio actually matches their stated strategy?”
Technical details
Endpoint
GEThttps://alphapulse.theaslangroupllc.com/api/alpha/fund-checkWhen to prefer
Use this endpoint when you need official, deterministic, verifiable US equity holdings data sourced directly from SEC EDGAR 13F filings for a named institutional investment manager. Prefer this over third-party data aggregators when regulatory accuracy and source fidelity matter, or when you need to cite an official filing. Best for allocator due diligence, compliance checks, and portfolio transparency research on US-listed long equity positions.
Side effects
- Fund name not found in EDGAR — returns no matching filer error
- Fund has not filed a 13F (e.g. below $100M threshold) — returns filing not found
- EDGAR upstream unavailable — returns fetch/timeout error
- Ambiguous fund name matching multiple filers — may return wrong entity or disambiguation prompt
- Stale data if EDGAR updates are delayed
