Analysis
KOYJ Co (121850) currently trades at 1,210 KRW, while our model-based Fair Value estimate is 1,107 KRW, implying the stock looks roughly 8.5% fairly valued today. The Quality Score stands at 32/100 (below-average quality), in the Basic Materials 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: low).
Over the trailing twelve months, KOYJ Co generated revenue of 13.6B KRW at a net margin of -63.7%. Revenue grew 22.2% year over year. It earns a return on equity of -95.5%. Net debt stands at 10.5B KRW. Fundamentals as of Jul 22, 2026
Our scenario range runs from 1,007 KRW (bear case) to 1,260 KRW (bull case); at 1,210 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. For context, the median of 10 Basic Materials peers we cover trades at -46% fair-value upside, at -9%, 121850 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 3 models by family
Widest divergence: Dividend Discount (1,009 KRW) versus Asset-Based (158.74 KRW). Highest evidence: Gordon GGM (70).
