Analysis
WON TECH Co (336570) currently trades at 5,330 KRW, while our model-based Fair Value estimate is 4,322 KRW, implying the stock looks roughly 18.9% overvalued today. The Quality Score stands at 78/100 (high quality), in the Healthcare sector. Bear case: priced above our estimate, the market already discounts strong expectations. Bull case: above-average quality can justify a premium, the entry price still matters most (evidence: high).
Over the trailing twelve months, WON TECH Co generated revenue of 160B KRW at a net margin of 21.1%. Revenue grew 7.6% year over year. It earns a return on equity of 22.7%. Net debt stands at 4.5B KRW. Fundamentals as of Jul 22, 2026
Our scenario range runs from 3,042 KRW (bear case) to 17,287 KRW (bull case); at 5,330 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 60% below its 52-week high, currently below its 200-day average. For context, the median of 10 Healthcare peers we cover trades at -26% fair-value upside, at -19%, 336570 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.
