Insider screener / Track records
Best Insider Track Records
Corporate insiders ranked by the realized return on their own open-market buys (SEC Form 4, code P). Each return is the current price versus the price the insider actually paid. Quality-gated to insiders with at least 5 priced buys so the numbers aren't single-trade flukes.

How this is computed: return per buy = current price ÷ the insider's actual purchase price − 1, averaged across their open-market buys (code P). “$-weighted” weights each buy by dollars invested. Insiders are identified by their SEC reporting-owner CIK where available.
This is unrealized, mark-to-market historical performance — not realized profit, not risk-adjusted, and not a prediction or investment advice. Past performance does not guarantee future results.
