What matters now
- The large discount to fair value meets weak quality (39/100). That raises the risk this is a value trap rather than a bargain.
- The price is below even our cautious bear case (1,341 KRW). The market is more pessimistic than our downside scenario.
- A fairly wide model range (1,341 KRW to 2,490 KRW) leaves room in how you read the outcome.

Analysis
Tongyang Inc (001520) currently trades at 1,120 KRW, while our model-based Fair Value estimate is 1,916 KRW, implying the stock looks roughly 71.0% undervalued today. The Quality Score stands at 39/100 (below-average quality), in the Basic Materials sector. Bull case: trading below our estimate, it may offer upside if the fundamentals hold. Bear case: a low price can be a value trap when quality is weak or the data is thin (evidence: medium), always confirm before acting.
Over the trailing twelve months, Tongyang Inc generated revenue of 600B KRW at a net margin of 6.2%. Revenue declined 19.8% year over year. It earns a return on equity of 5.2%. Net debt stands at 497B KRW. Fundamentals as of Jul 22, 2026
Our scenario range runs from 1,341 KRW (bear case) to 2,490 KRW (bull case); at 1,120 KRW, the current price sits below 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 16% below its 52-week high and 107% above its 52-week low, currently above its 200-day average. For context, the median of 10 Basic Materials peers we cover trades at -59% fair-value upside, at 71%, 001520 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 10 models by family
