Very Strong conviction signal

Scored in the top tier across multiple factors. Fewer than 5% of insider trades receive this rating.

~$1.8M purchase

Trades over $1M are rare. When insiders put this much of their own money on the line, they tend to have high conviction in their company's direction.

CEO and President

CEOs have the deepest knowledge of company operations. Academic research shows CEO purchases outperform other insider trades by a wide margin.

4 insiders traded in the same window

When multiple insiders independently buy within 30 days, it's called a cluster. Studies show clustered insider purchases outperform solo trades significantly, because several people with inside knowledge are reaching the same conclusion.

+16.1% in 90 days (S&P 500: +6.2%)

This trade beat the S&P 500 by 9.9 percentage points over 90 days. We track performance on every insider trade so you can see who consistently outperforms.

What is this?

When company executives buy or sell their own stock, they must report it to the SEC within 2 days. These public filings reveal what the people who know the company best are doing with their own money.

Why does it matter?

Insiders can sell for many reasons (taxes, diversification, expenses), but they generally only buy for one: they think the stock is going up. That's why insider purchases are more predictive than sales.

What makes a trade "strong"?

We score trades on 15+ factors: the insider's role (CEO > director), trade size relative to their salary, whether other insiders also bought (clusters), and historical accuracy of the insider.
