About QW Research

Free institutional ownership analytics built on SEC 13F filings.

What is QW Research?

QW Research is a free tool that lets you see which hedge funds, mutual funds, and other large institutions own shares of any publicly traded stock. We process data from SEC EDGAR 13F filings and present it in clean, actionable dashboards — no paywall, no account required.

How We Collect Data

Our automated pipeline processes data directly from SEC EDGAR — the same primary source used by Bloomberg, Reuters, and other financial data providers.

1. Collect

Parse 13F-HR filings from SEC EDGAR for 8,000+ institutions every quarter.

2. Enrich

Map CUSIPs to tickers, resolve company names, and cross-reference with XBRL financial data.

3. Analyze

Calculate ownership percentages, crowding scores, and quarter-over-quarter changes.

What You Can Do

Look up any stock — see how many institutions hold it, total shares held, and ownership percentage.
Track ownership trends — view 8 quarters of institutional ownership history with interactive charts.
Detect crowding — our crowding analysis flags stocks where institutional positioning is unusually concentrated.
See ownership flows — Sankey diagrams show how institutional capital moves between positions each quarter.
