New: Insider Cluster Buy Detector — 3+ insiders buying the same stock, flagged automatically

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.

Sample fields / output

  • ticker & company
  • cluster_size (number of distinct insiders)
  • window_days (30 / 60 / 90)
  • insider_names & roles (CEO/CFO/Director/10%-owner)
  • transaction_dates
  • shares & dollar_value
  • buy_type

Example use cases

  • Surface high-conviction insider clusters as a weekly watchlist.
  • Back-test cluster signals against forward returns.
  • Alert on multi-insider accumulation in a specific sector or market cap band.
