Our scenario range runs from 6,161 KRW (bear case) to 10,269 KRW (bull case); at 9,160 KRW, 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 46% below its 52-week high, currently below its 200-day average. For context, the median of 10 Industrials peers we cover trades at -26% fair-value upside, at -10%, 081000 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 11 models by family
