What is holding the score back?

  • ✓ Cluster breadth is broad · 4+ insiders
  • ✓ Role scores high · most senior buyer: Chief Operating Officer

Purchase-size comments are relative to the model scale. Average daily volume is a separate market-context diagnostic.

US-v1.2 ranks qualifying equity purchases under the current 180-day rules. The score is a research priority, not a return forecast or probability. Backtests have not shown that a higher US score is followed by better returns.
