Analysis
ADTechnology Co (200710) currently trades at 30,500 KRW, while our model-based Fair Value estimate is 6,229 KRW, implying the stock looks roughly 79.6% 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, ADTechnology Co generated revenue of 224B KRW at a net margin of 5.7%. Revenue declined 68.0% year over year. Net debt stands at 24.5B KRW. Fundamentals as of Jul 20, 2026
Our scenario range runs from 4,360 KRW (bear case) to 6,229 KRW (bull case); at 30,500 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 51% below its 52-week high and 92% 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 -80%, 200710 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 14 models by family
Widest divergence: Asset-Based (7,005 KRW) versus Earnings-Based (4,257 KRW). Highest evidence: Residual Income (76).
