Strong conviction signal

Scored above average across multiple factors. Roughly 15% of insider trades qualify as Strong.

~$15M 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.

2 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.

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.
