Fair value as of: Jul 22, 2026
From 26 valuation models · updated 19 days ago
Share price +43.0% over the past month.
Below-average quality, and screening another 63% overvalued on our models.
What matters now
- The price sits above even our optimistic bull case (7,719 KRW). The favourable scenario is already priced in.
- Weak quality (43/100) and above fair value at the same time, the margin of safety is missing on both counts.
- The model range is unusually wide (2,631 KRW to 7,719 KRW). The outcome hinges heavily on assumptions, so read the point estimate with caution.

Analysis
Pentastone Electronics, Inc (332570) currently trades at 8,740 KRW, while our model-based Fair Value estimate is 3,243 KRW, implying the stock looks roughly 62.9% overvalued today. The Quality Score stands at 43/100 (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: high).
Over the trailing twelve months, Pentastone Electronics, Inc generated revenue of 50.7B KRW at a net margin of 12.4%. Revenue declined 1.0% year over year. It earns a return on equity of -4.6%. Net debt stands at 32.4B KRW. Fundamentals as of Jul 22, 2026
Our scenario range runs from 2,631 KRW (bear case) to 7,719 KRW (bull case); at 8,740 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 42% below its 52-week high and 212% above its 52-week low, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at -61% fair-value upside, at -63%, 332570 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.
All 26 models by family
Widest divergence: Growth Earnings (10,440 KRW) versus Economic Profit (875.86 KRW). Highest evidence: Growth DCF (80).
