Leaderboard
Insiders and issuers ranked by realized signed return on open-market Form 4 trades. Returns are signed: a sale followed by a rally counts against the seller.
What the metrics mean
Return - the insider's signed return per trade, averaged. A +10% stock move on a buy scores +10%; on a sell, -10%. Because most insider activity is concentrated at rallying stocks, this metric correlates with raw stock performance and doesn't fully isolate timing skill from market drift.
Edge - signed return minus the stock's average forward N-day return over the same period. An insider with +5% edge consistently chose better days to trade than someone who'd picked a random day in the same window. Isolates timing skill from "the stock just went up."
Neither metric is the same as ranking stocks by raw return - that would just surface the best-performing tickers, which you can get from any market screener.
