What matters now

  • The price sits above even our optimistic bull case ($0.0004). The favourable scenario is already priced in.
  • Weak quality (30/100) and above fair value at the same time, the margin of safety is missing on both counts.
  • The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution.

All values are scores from 0 to 100 (100 = best against fixed, research-based bands), not percentages. The three market factors (momentum, 52-week proximity, low volatility) are displayed but carry zero weight in the headline number: market sentiment is not a business property.
