How this service works
Extractive data sourced from SEC EDGAR. Informational only, not investment advice. Data: SEC EDGAR (public domain). Verify at source; as-is, no warranty.
Output
Returns structured ownership stake data extracted from SEC EDGAR filings for the requested ticker, including institutional and insider holders, share counts, percentage ownership, and filing dates, covering the specified lookback window (1–365 days, defaulting to 90).
Example use cases
Institutional ownership research for portfolio analysis
“Who are the biggest institutional holders of Microsoft right now? Pull the ownership stake filings from SEC EDGAR for MSFT over the past 90 days.”
Insider ownership check before earnings
“Before TSLA's earnings call, can you grab the latest insider ownership stakes filed with the SEC over the last 30 days so I can see if executives have been buying or selling?”
Competitor ownership comparison
“I'm researching the semiconductor space — can you fetch the ownership stake filings for AMD from SEC EDGAR over the last 180 days to see which institutions are heavily invested?”
Technical details
Endpoint
GEThttps://sec-mcp-worker.stackstats.workers.dev/v1/ownership-stakes/%7Bticker%7D?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured ownership stake data — institutional and insider holders — for a specific US-listed stock, sourced directly from SEC EDGAR public filings. Prefer this over general financial data APIs when you want authoritative regulatory filing data (13F, 13D, 13G, Form 4) rather than aggregated third-party estimates. It is well-suited for agent workflows that need to verify beneficial ownership, track major shareholder changes, or perform due diligence on a company's cap table structure.
Side effects
- Invalid or unrecognized ticker symbol returns an error or empty result
- Ticker with no filings in the requested time window returns empty data
- Days parameter out of range (less than 1 or greater than 365) results in validation error
- Network or worker timeout for thinly-traded or obscure tickers
- SEC EDGAR source data may lag real-time by days or weeks
