How to read this chart
60‑month range 5,770 KRW – 50,500 KRW · fair‑value band 10,448 KRW – 17,720 KRW · the 22,700 KRW price screens above the 14,167 KRW fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). Dashed = 300-day average. As of Jul 22, 2026.
Analysis
KOSES Co (089890) currently trades at 22,700 KRW, while our model-based Fair Value estimate is 14,167 KRW, implying the stock looks roughly 37.6% overvalued today. The Quality Score stands at 83/100 (high 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: high).
Over the trailing twelve months, KOSES Co generated revenue of 83.8B KRW at a net margin of 13.7%. Revenue grew 6.8% year over year. It earns a return on equity of 187.1%. Net debt stands at 743M KRW. Fundamentals as of Jul 22, 2026
Our scenario range runs from 10,448 KRW (bear case) to 17,720 KRW (bull case); at 22,700 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 56% below its 52-week high and 232% above its 52-week low, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at -68% fair-value upside, at -38%, 089890 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 24 models by family
Widest divergence: DCF Models (18,534 KRW) versus Asset-Based (2,943 KRW). Highest evidence: Growth DCF (80).
