Analysis
Senko Co (347000) currently trades at 1,753 KRW, while our model-based Fair Value estimate is 1,196 KRW, implying the stock looks roughly 31.8% overvalued today. The Quality Score stands at 57/100 (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: high).
Over the trailing twelve months, Senko Co generated revenue of 39.1B KRW at a net margin of 16.3%. Revenue grew 36.1% year over year. It earns a return on equity of 10.7%. Fundamentals as of Jul 22, 2026
Our scenario range runs from 1,052 KRW (bear case) to 1,484 KRW (bull case); at 1,753 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 43% below its 52-week high and 5% above its 52-week low, currently below its 200-day average. For context, the median of 10 Industrials peers we cover trades at -33% fair-value upside, at -32%, 347000 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
