Each bar shows the contribution to the current score; the weights and formula stay unchanged.

Purchase size+20.1 / 25
Role+15.0 / 20
Recency+3.0 / 10
Conviction+10.0 / 10

What is holding the score back?

  • ⚠ Purchase activity is becoming less recent
  • ✓ Cluster breadth is broad · 4+ insiders
  • ✓ Role scores high · most senior buyer: Chief Financial 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.
