Analysis
Woojin Inc (105840) currently trades at 15,170 KRW, while our model-based Fair Value estimate is 7,435 KRW, implying the stock looks roughly 51.0% overvalued today. The Quality Score stands at 51/100 (solid quality), in the Technology 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: medium).
Over the trailing twelve months, Woojin Inc generated revenue of 160B KRW at a net margin of 8.4%. Revenue grew 36.9% year over year. It earns a return on equity of 7.3%. Net debt stands at 26.0B KRW. Fundamentals as of Jul 24, 2026
Our scenario range runs from 6,468 KRW (bear case) to 9,516 KRW (bull case); at 15,170 KRW, 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 52% below its 52-week high and 65% above its 52-week low, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at -45% fair-value upside, at -51%, 105840 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 16 models by family
Widest divergence: Multiples (8,624 KRW) versus Dividend Discount (1,968 KRW). Highest evidence: Residual Income (76).
