How this service works
Fund holdings intelligence for any US mutual fund or ETF — top positions, position weights, concentration (top-5/top-10 %), and quarter-over-quarter holdings changes. Sourced from SEC Form N-PORT filings (structured EDGAR data, not a static snapshot). Accepts fund ticker, CIK, or fund name. For investing, allocation-research, and portfolio-overlap agents.
Output
Returns structured data including the fund's top positions with their ticker symbols and weight percentages, top-5 and top-10 concentration metrics, and a quarter-over-quarter diff showing positions added, removed, or changed in weight — all sourced from the most recent SEC Form N-PORT filing for the requested fund.
Example use cases
Detect portfolio overlap across client funds
“Check the top 5 holdings for both VTSAX and VTI to see how much overlap exists between these two funds, and flag any positions that represent more than 5% of either portfolio.”
Monitor concentration risk in growth ETFs
“Get the latest N-PORT data for QQQ and TQQQ, and tell me what percentage of each fund is concentrated in their top 10 holdings—I want to understand the concentration difference between these two.”
Track institutional fund allocation shifts
“Pull the most recent quarter-over-quarter changes for the Fidelity Magellan Fund, especially any large positions that were added, removed, or significantly reduced in weight compared to last quarter.”
Technical details
Endpoint
GEThttps://filingspulse.theaslangroupllc.com/api/filings/fund-holdings?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, up-to-date mutual fund or ETF holdings data sourced directly from SEC Form N-PORT filings rather than a third-party data vendor snapshot. Ideal for portfolio-overlap analysis, allocation research, concentration risk assessment, or monitoring quarter-over-quarter shifts in institutional fund positions. Prefer this over generic financial data APIs when regulatory filing accuracy and recency matter, or when you need to accept fund identifiers in multiple formats (ticker, CIK, or name).
Side effects
- Fund ticker not found in EDGAR — returns 404 or empty result if the ticker is not mapped to a CIK
- CIK does not correspond to a fund with N-PORT filings — returns error if the entity is not a registered investment company
- No recent N-PORT filing available — may return stale or missing data if the fund has not filed recently
- Ambiguous fund name matching multiple funds — may require disambiguation via CIK
- Payment failure (x402) — $0.25 USDC not authorized, returns 402 status
