What are insiders buying?

Insiders sell for many reasons: taxes, diversification, a new house. They buy for one: they think the stock is worth more. Open-market purchases by the people who run a company are rare enough to be worth a look.

How to read this page

How it’s measured. Open-market buys and sells reported on SEC Form 4 by officers, directors and 10% owners of S&P 500 and Nasdaq-100 companies over the last 21 days.

Sources. Daily prices from Financial Modeling Prep; insider filings on SEC Form 4.

Only open-market trades count. Option exercises, grants and planned sales filed under trading plans are excluded where the filing marks them. A 10% owner can be a fund rather than a person.

Insider buying is a reason to look closer, not a signal on its own. This is information, not investment advice.
