What matters now
- Weak quality (10/100) and above fair value at the same time, the margin of safety is missing on both counts.
- The model range is unusually wide (9,402 KRW to 36,889 KRW). The outcome hinges heavily on assumptions, so read the point estimate with caution.
- The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution.

Analysis
Seojin System Co (178320) currently trades at 36,950 KRW, while our model-based Fair Value estimate is 23,145 KRW, implying the stock looks roughly 37.4% overvalued today. The Quality Score stands at 10/100 (below-average 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, Seojin System Co generated revenue of 1.1T KRW at a net margin of -11.5%. Revenue declined 0.4% year over year. It earns a return on equity of -14.6%. Net debt stands at 1.1T KRW. Fundamentals as of Aug 13, 2026
Our scenario range runs from 9,402 KRW (bear case) to 36,889 KRW (bull case); at 36,950 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 56% below its 52-week high and 101% above its 52-week low, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at -50% fair-value upside, at -37%, 178320 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 2 models by family
Widest divergence: Multiples (28,623 KRW) versus Asset-Based (7,729 KRW). Highest evidence: EV/EBITDA (54).
