Why This Trade Stands Out
Strong conviction signal
Scored above average across multiple factors. Roughly 15% of insider trades qualify as Strong.
~$294K purchase
A meaningful investment of personal capital. The average insider purchase is around $150K, putting this in the typical range for serious positions.
SVP & Chief Financial Officer
CFOs have direct access to financials before they become public. Their trades are among the most closely watched by institutional investors.
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.
+24.3% in 90 days (S&P 500: -0.3%)
This trade beat the S&P 500 by 24.6 percentage points over 90 days. We track performance on every insider trade so you can see who consistently outperforms.

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.
