This endpoint returns a list of institutional holders, including each holder’s reported position, percent held, and estimated value. Supports filtering and sorting.
Asset Type Compatibility
This endpoint is primarily relevant for stocks.
For ETFs and mutual funds, the response is typically empty because institutional holder filings in this format are equity-focused in the upstream source. It commonly returns:
"result": {
"total_count": 0,
"items_count": 0,
"items": []
}When to Use This Endpoint
- Populate “Top Institutional Holders” tables for stocks.
- Enable holder-based filtering and ranking (e.g., show only holders above X%).
- Support ownership analytics and concentration views (e.g., top holders by value).
