Insider Performance Leaderboard
Not all insider trades are created equal. The Lynx MI Leaderboard ranks corporate insiders by their actual stock performance after disclosed purchases, helping you identify which executives have the best track records of buying before price appreciation.
How the Rankings Work
We track every insider purchase reported via SEC Form 4 filings and measure the stock's performance 30 days and 90 days after the trade. Insiders are ranked by their average post-trade return, win rate (percentage of trades followed by positive returns), total trade count, and aggregate dollar volume. The leaderboard updates daily as new price data becomes available, giving you a continuously fresh view of which insiders are consistently ahead of the market.
Academic research has consistently shown that insider purchases — particularly by C-suite executives like CEOs and CFOs — tend to outperform the broader market. A landmark study by Lakonishok and Lee (2001) found that insider purchases beat the market by an average of 4.8% over the following 12 months. Our leaderboard helps you identify which specific insiders drive that outperformance.
