Learn about insider trades →Frequently Asked Questions
Where does the trading data come from?
All data is sourced from official public filings. Institutional holdings come from SEC Form 13F, insider transactions from Form 4, and congressional trades from disclosures required under the STOCK Act. StockInsider organizes these public records into a fast, easy-to-follow experience.
How can I use StockInsider for my own investing?
StockInsider is an informational and research tool — it does not provide investment advice. Many people use it to generate ideas, study how legendary investors position their portfolios, and stay informed about notable Congress and insider activity. You are always responsible for your own investment decisions.
Which investors and politicians can I track?
You can follow dozens of well-known investors and funds, including Warren Buffett, Cathie Wood, Michael Burry, Ray Dalio, and Bill Ackman, alongside frequently discussed members of Congress such as Nancy Pelosi. New investors and portfolios are added regularly.
Is the trade data complete?
Filings only capture what regulators require to be disclosed. Smaller positions and certain transaction types may not appear in public filings, and there can be a reporting delay between when a trade happens and when it must be disclosed. We present the data for informational purposes only.
Is StockInsider free?
Yes. You can download StockInsider on iOS and Android and start tracking top investors, Congress trades, and insider activity for free.
