WHY THIS SIGNAL?
Score anatomy
Each bar shows the contribution to the current score; the weights and formula stay unchanged.
What is holding the score back?
- ⚠ Cluster breadth is moderate · 1 insider(s), not 4+
- ⚠ Purchase size is modest relative to the model scale
- ⚠ Purchase activity is becoming less recent
- ✓ Role scores high · most senior buyer: Director
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.
Insider activity timeline
Owner lanes show the latest 180 days. Symbol shape identifies the transaction type; sales remain context only.

Purchase breadth & concentration
Roles in the peak window: Director. Concentration uses priced qualifying P lines only and does not change the saved score.
