What it does
This actor scans insider transactions and flags clusters — three or more insiders (CEOs, CFOs, directors, or 10%-owners) buying the same stock inside a 30, 60, or 90-day window. Academic work (Lakonishok-Lee) found cluster signals outperform single-insider trades by roughly 4-7%, so isolating them surfaces a higher-conviction signal than a raw Form 4 feed.
Who it's for
Equity analysts, signal-driven traders, and quant teams who want a focused insider-buying signal without paying for Bloomberg, TipRanks, or OpenInsider Pro.
