Analysis
Onejoon Co (382840) currently trades at 5,030 KRW, while our model-based Fair Value estimate is 3,905 KRW, implying the stock looks roughly 22.4% overvalued today. The Quality Score stands at 59/100 (solid quality), in the Industrials 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, Onejoon Co generated revenue of 52.5B KRW at a net margin of -30.7%. It earns a return on equity of -14.4%. Net debt stands at 10.5B KRW. Fundamentals as of Jul 22, 2026
Our scenario range runs from 2,756 KRW (bear case) to 5,053 KRW (bull case); at 5,030 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 59% below its 52-week high, currently below its 200-day average. For context, the median of 10 Industrials peers we cover trades at -48% fair-value upside, at -22%, 382840 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 13 models by family
