Fund Holdings

Returns per-security holdings from SEC Form N-PORT primary documents, one row per investment-or-security line in a mutual fund / ETF / closed-end fund's monthly portfolio report. Use this when the user asks about: which funds hold a specific stock or bond, a fund's complete portfolio composition, fund-level derivative exposure (swaps, options, futures), rep.

Filters

filing_id	EDGAR accession number, returns all holdings from one specific N-PORT filing (one fund-month).
filer_cik	Fund trust CIK (10-digit, padded with leading zeros). Returns the trust's holdings across all reporting months.
filer_name	Case-insensitive substring against fund trust name (e.g., 'iShares', 'Vanguard', 'SPDR').
period_ending	Reporting month-end (YYYY-MM-DD). Restricts results to one reporting period.
name	Case-insensitive substring against the holding issuer name (e.g., 'Apple', 'Treasury', 'Goldman Sachs').
cusip	Exact 9-character CUSIP. Most reliable identifier for equity and debt holdings in N-PORT.
ticker	Exact ticker symbol if filer included it in the identifiers block (less common than CUSIP).
isin	Exact ISIN if filer included it in the identifiers block.
asset_cat	SEC's asset-category code, case-insensitive. The data holds exactly these: EC common equity; EP preferred equity; DBT debt, Treasuries included; LON…
is_derivative	True returns only derivative rows (asset_cat starting with 'D'). False returns only non-derivative rows. Omit for both.
derivative_type	Structural derivative type, derived from which `<derivativeInfo>` child element is present in the filing.
country	ISO-2 country code of the holding (e.g., 'US', 'GB', 'JP').
payoff_profile	Filter to long or short positions per N-PORT payoffProfile field.
min_value_usd	Minimum fair value in USD. Use to focus on large positions only.
min_pct_of_portfolio	Minimum percentage of fund net assets (0-100 scale). Use to focus on concentrated positions.
min_notional	Minimum derivative notional amount in the contract's currency. This is exposure, not fair value: use min_notional to ask how big the bet is and min_value_usd to ask what the position is worth today. Rows with no notional (options, for example) are excluded by any positive floor.
counterparty	Case-insensitive substring against the derivative counterparty (the dealer or clearing house on the other side), e.g. 'Morgan Stanley' across funds. The source writes 'N/A' where no counterparty is disclosed, and that value is kept.
expiration_since	ISO date (YYYY-MM-DD). Only derivatives expiring on or after this date, across futures, options, swaps and forwards. Rows whose value is not a real date are excluded from the window.
expiration_until	ISO date (YYYY-MM-DD). Only derivatives expiring on or before this date. Pair with expiration_since for a rollover window.
maturity_since	ISO date (YYYY-MM-DD). Only debt holdings maturing on or after this date. Pair with maturity_until to build a maturity ladder.
maturity_until	ISO date (YYYY-MM-DD). Only debt holdings maturing on or before this date.
since	ISO date (YYYY-MM-DD). Only holdings whose period_ending >= this date.
until	ISO date (YYYY-MM-DD). Only holdings whose period_ending <= this date.
sort_by	Default: value_usd.
sort_order	Default: desc (largest / most recent first).
limit	Maximum records to return. Default 50, max 500.
