Why This Trade Stands Out
Very Strong conviction signal
Scored in the top tier across multiple factors. Fewer than 5% of insider trades receive this rating.
~$2.6M 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.
President & CEO
CEOs have the deepest knowledge of company operations. Academic research shows CEO purchases outperform other insider trades by a wide margin.
3 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.
+2.4% in 90 days (S&P 500: +12.2%)
This trade underperformed the S&P 500 by 9.8 percentage points. Not every insider trade wins. We track all of them so you can focus on the insiders with the best records.

See who else bought · FreeOn May 7, 2025, Calafiore Massimo — President & CEO of Orthofix Medical Inc. — filed a Form 4 with the SEC disclosing an open-market purchase of approximately ~$2.6M in Orthofix Medical Inc. (OFIX) stock.

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.
