YAS Co., Ltd. (255440) Fair Value & Analysis

Technology · KR · Market cap 84.3B KRW

A solid business, but screening 67% overvalued on our models.

What matters now

• The price sits above even our optimistic bull case (3,026 KRW). The favourable scenario is already priced in.
• The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution.
• Solid but not exceptional quality (63/100) and above fair value, neither a clear bargain nor a standout compounder.
• A fairly wide model range (1,598 KRW to 3,026 KRW) leaves room in how you read the outcome.

Analysis

YAS Co., Ltd. (255440) currently trades at 7,410 KRW, while our model-based Fair Value estimate is 2,421 KRW, implying the stock looks roughly 67.3% overvalued today. The Quality Score stands at 63/100 (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: low).

Over the trailing twelve months, YAS Co., Ltd. generated revenue of 63.4B KRW at a net margin of 8.2%. It earns a return on equity of 3.8%. Fundamentals as of Aug 13, 2026

Our scenario range runs from 1,598 KRW (bear case) to 3,026 KRW (bull case); at 7,410 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 45% below its 52-week high and 14% above its 52-week low, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at -72% fair-value upside, at -67%, 255440 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.

Frequently asked questions

How we calculate Fair Value

Each company is valued through a stack of independent intrinsic-value models (DCF variants, residual-income, multiples and more), blended into one family-balanced consensus and weighted by how much trustworthy data backs it. A separate quality layer scores the fundamentals. Every input is real reported data, nothing guessed.
