Why This Trade Stands Out
Strong conviction signal
Scored above average across multiple factors. Roughly 15% of insider trades qualify as Strong.
~$651K sale
A significant position. Insiders who invest $500K+ of their own money typically have strong views on their company's near-term outlook.
President & COO
Corporate insiders must file trades with the SEC within 2 business days. Their unique access to non-public information makes these filings valuable data points.
-6.6% in 90 days (S&P 500: +7.8%)
This trade underperformed the S&P 500 by 14.4 percentage points. Not every insider trade wins. We track all of them so you can focus on the insiders with the best records.

How to Read Insider Trades
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.
