Fair value as of: Aug 13, 2026
From 23 valuation models · updated today
Fair value updated Aug 13, 2026, revised from 172.43 KRW to 424.63 KRW (+146.3%) since Jul 22, 2026. Share price +23.9% over the past month.
Below-average quality, and screening another 88% overvalued on our models.
What matters now
- The price sits above even our optimistic bull case (591.82 KRW). The favourable scenario is already priced in.
- Weak quality (40/100) and above fair value at the same time, the margin of safety is missing on both counts.
- The model range is unusually wide (218.60 KRW to 591.82 KRW). The outcome hinges heavily on assumptions, so read the point estimate with caution.

60‑month range 2,415 KRW – 39,350 KRW · fair‑value band 218.60 KRW – 591.82 KRW · the 3,470 KRW price screens above the 424.63 KRW fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). Dashed = 300-day average. As of Aug 13, 2026.
Analysis
DE&T Co (079810) currently trades at 3,470 KRW, while our model-based Fair Value estimate is 424.63 KRW, implying the stock looks roughly 87.8% overvalued today. The Quality Score stands at 40/100 (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, DE&T Co generated revenue of 45.2B KRW at a net margin of 6.7%. Revenue grew 182.1% year over year. Net debt stands at 4.8B KRW. Fundamentals as of Aug 13, 2026
Our scenario range runs from 218.60 KRW (bear case) to 591.82 KRW (bull case); at 3,470 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 59% below its 52-week high and 1% above its 52-week low, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at -56% fair-value upside, at -88%, 079810 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 23 models by family
Widest divergence: DCF Models (31,881 KRW) versus Earnings-Based (172.90 KRW). Highest evidence: Growth DCF (80).
