When 3+ insiders buy open-market shares while the stock is >20% below its 52-week high,
the average forward-12-month return historically beats SPX by 9-14 percentage points
(Cohen-Malloy-Pomorski 2012; Cziraki-Lyandres-Michaely 2021). Insiders have asymmetric
information; clustered buying at a drawdown is the strongest known revealed-preference
signal. This page filters live insider-cluster data for exactly that pattern, ranked by
a composite Conviction Score = drawdown_depth × n_insiders × role_weight.
