Fair value as of: Jul 22, 2026
From 1 valuation models · updated 19 days ago
Share price −10.6% over the past month.
Below-average quality, and screening another 71% overvalued on our models.
What matters now
- The price sits above even our optimistic bull case (2,701 KRW). The favourable scenario is already priced in.
- Weak quality (42/100) and above fair value at the same time, the margin of safety is missing on both counts.
- The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution.
- A fairly wide model range (1,426 KRW to 2,701 KRW) leaves room in how you read the outcome.

Analysis
Wonil T&I Co (136150) currently trades at 7,570 KRW, while our model-based Fair Value estimate is 2,160 KRW, implying the stock looks roughly 71.5% overvalued today. The Quality Score stands at 42/100 (below-average 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: low).
Over the trailing twelve months, Wonil T&I Co generated revenue of 29.1B KRW at a net margin of -42.5%. Net debt stands at 3.6B KRW. Fundamentals as of Jul 22, 2026
Our scenario range runs from 1,426 KRW (bear case) to 2,701 KRW (bull case); at 7,570 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 78% below its 52-week high, currently below its 200-day average. For context, the median of 10 Industrials peers we cover trades at -48% fair-value upside, at -71%, 136150 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.
