How this service works
Institutional holdings / 13F ownership analysis for any US-listed company — fund flows, major holders, hedge-fund positions, and smart-money positioning shifts quarter over quarter. From EDGAR SC 13D/G filings plus live research, for investing and equity-research agents.
Output
Returns structured institutional ownership data parsed from 13F filings, including a ranked list of major holders, their ownership percentages and share counts, net quarter-over-quarter changes in position size, fund flow direction (buy/sell/hold), and smart-money sentiment indicators derived from aggregated filing data.
Example use cases
Track smart-money rotation in mega-cap tech
“Which major institutional investors have been accumulating or dumping positions in Apple, Microsoft, and Tesla over the past two quarters? I want to see where the smart money is moving.”
Identify activist fund positioning moves
“Show me which hedge funds and activist investors have significantly increased their stakes in smaller-cap growth stocks over the last quarter — I'm looking for signals on who's betting big on turnarounds.”
Monitor fund flow sentiment for portfolio risk
“Pull the latest 13F data on our top ten holdings and tell me if major institutional shareholders are buying more or bailing out — I need to know if we're swimming with or against the smart-money tide.”
Technical details
Endpoint
GEThttps://filingspulse.vercel.app/api/filings/ownershipWhen to prefer
Use this endpoint when you need to understand who the major institutional shareholders of a publicly traded company are, how their positions have changed quarter over quarter, and what smart-money sentiment looks like — particularly for equity research, due diligence, or investment thesis building. Prefer this over general SEC search endpoints when the specific question is about 13F ownership concentration and fund flow dynamics rather than textual filing content.
Side effects
- Unknown or invalid ticker symbol returns an error or empty result
- Company has no 13F filing history (e.g. private company) returns no data
- Requested quarter not yet available due to SEC reporting lag (45-day delay after quarter end)
- Rate limiting or payment failure returns a 402 or 429 error
- SEC EDGAR data temporarily unavailable causes fetch failure
