Analysis

The Quality Score stands at 54/100 (solid quality), in the Healthcare sector. Bull case: trading below our estimate, it may offer upside if the fundamentals hold. Bear case: a low price can be a value trap when quality is weak or the data is thin (evidence: high), always confirm before acting.

Our scenario range runs from 81.79 TWD (bear case) to 136.32 TWD (bull case); at 89.50 TWD, the current price sits within 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 41% below its 52-week high, currently below its 200-day average. For context, the median of 10 Healthcare peers we cover trades at -43% fair-value upside, at 22%, 5312 screens cheaper 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
Widest divergence: DCF Models (137.08 TWD) versus Earnings-Based (35.73 TWD). Highest evidence: Growth DCF (80).
