Score anatomy

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

Cluster+7.0 / 35

Purchase size+22.2 / 25

Role+15.5 / 20

Recency+3.3 / 10

Conviction+10.0 / 10

What is holding the score back?

⚠ Cluster breadth is moderate · 1 insider(s), not 4+
⚠ Role uses the day's average · no purchase states a title on the role scale
⚠ Purchase activity is becoming less recent

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.
