  • ✓ Role scores high · most senior buyer: Director
  • ✓ Recent activity · latest purchase 2026-09-30

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.
