Fair value as of: Aug 13, 2026
From 6 valuation models · updated today
Fair value updated Aug 13, 2026, revised from 34,142 KRW to 29,700 KRW (−13.0%) since Jul 16, 2026. Share price −17.6% over the past month.
Below-average quality, screening 100% undervalued on our models.
What matters now
- The large discount to fair value meets weak quality (44/100). That raises the risk this is a value trap rather than a bargain.
- The price is below even our cautious bear case (22,275 KRW). The market is more pessimistic than our downside scenario.
- For a financial, book-value and earnings-based methods matter more than a cash-flow DCF, which fits banks and insurers poorly.

Analysis
BNK Financial Group (138930) currently trades at 14,850 KRW, while our model-based Fair Value estimate is 29,700 KRW, implying the stock looks roughly 100.0% undervalued today. The Quality Score stands at 44/100 (below-average quality), in the Financial Services 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: high), always confirm before acting.
Trailing-twelve-month revenue stands at 5.4T KRW. Revenue grew 21.3% year over year. It earns a return on equity of 7.5%. Net debt stands at 17.2T KRW. Fundamentals as of Aug 13, 2026
Our scenario range runs from 22,275 KRW (bear case) to 37,125 KRW (bull case); at 14,850 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 34% below its 52-week high and 38% above its 52-week low, currently below its 200-day average. For context, the median of 10 Financial Services peers we cover trades at 47% fair-value upside, at 100%, 138930 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 6 models by family
Widest divergence: Multiples (34,142 KRW) versus Dividend Discount (15,433 KRW). Highest evidence: Residual Income (76).
