Fair value as of: Jul 20, 2026
From 1 valuation models · updated 20 days ago
Share price +7.3% over the past month.
Below-average quality, and screening another 49% overvalued on our models.
What matters now
- The price sits above even our optimistic bull case (24,965 KRW). The favourable scenario is already priced in.
- Weak quality (21/100) 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 (13,186 KRW to 24,965 KRW) leaves room in how you read the outcome.

Analysis
JS Link, Inc (127120) currently trades at 39,150 KRW, while our model-based Fair Value estimate is 19,974 KRW, implying the stock looks roughly 49.0% overvalued today. The Quality Score stands at 21/100 (below-average quality), in the Healthcare 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, JS Link, Inc generated revenue of 20.3B KRW at a net margin of -77.6%. Revenue grew 69.4% year over year. It earns a return on equity of -26.3%. Net debt stands at 2.1B KRW. Fundamentals as of Jul 20, 2026
Our scenario range runs from 13,186 KRW (bear case) to 24,965 KRW (bull case); at 39,150 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 22% below its 52-week high and 337% above its 52-week low, currently above its 200-day average. For context, the median of 10 Healthcare peers we cover trades at -43% fair-value upside, at -49%, 127120 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.
