Our scenario range runs from ¥6.00 (bear case) to ¥9.73 (bull case); at ¥15.35, 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 35% below its 52-week high and 7% above its 52-week low, currently below its 200-day average. For context, the median of 10 Healthcare peers we cover trades at -43% fair-value upside, at -49%, 300653 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 26 models by family
