Our scenario range runs from ¥0.6600 (bear case) to ¥1.09 (bull case); at ¥3.85, the current price sits above that range. Bear and bull are the same models run on conservative and optimistic assumptions (margins, growth, valuation multiples), so a plausible valuation range, not a price target. The share trades about 49% below its 52-week high and 52% above its 52-week low, currently below its 200-day average. For context, the median of 10 Healthcare peers we cover trades at -25% fair-value upside, at -77%, 600666 screens richer than that median.
Fair Value models
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted blend. Evidence (0–100) measures how completely this model’s inputs are available: well-fed models carry more weight in the blend. The spread across models is intentional, each one stresses a different value driver; dividend models, for instance, come out structurally low when payout is small.
All 10 models by family
Widest divergence: DCF Models (¥1.48) versus Earnings-Based (¥0.2400). Highest evidence: Residual Income (76).
