Fair Value models

The price assumes far more growth than our models allow for, so the models scatter widely (321.43 KRW to 3,948 KRW). Read the Fair Value as a cautious anchor, not a price target; the Growth Forecast section shows what the price assumes.
Bear 2,296 KRW Fair Value 2,327 KRW Bull 3,420 KRW
Price 20,500 KRW · Downside -88.7%
Model ⓘEach model values the company its own way (discounted cash flow, earnings, assets, dividends). The fair value above starts from their evidence-weighted blend, not from a single model. In cyclical trough or peak years, after dilution or a stock split it is adjusted afterwards, so it can sit above or below the models. Based on fiscal year 2025 figures (about 10 months old). Earnings retained since then (255.61 KRW per share) are deliberately not added. Bear ⓘBear = the cautious scenario: the same model computed with conservative anchors (lower growth, margins and valuation multiples). Together with Bull it frames a plausible valuation range, not a price target.BaseBull ⓘBull = the optimistic scenario: the same model computed with favourable anchors (higher growth, margins and valuation multiples). Together with Bear it frames a plausible valuation range, not a price target. If a model's bull case is above four times its base value, the table shows that limit with a > sign (like the overall Bull above): beyond it no assumption holds. Coverage ⓘCoverage = how well-backed THIS model's estimate is for this stock (0–100): how complete and reliable its input data are, and how well the model fits the company. The final Fair Value is an evidence-weighted blend, so better-evidenced models count more. Green ≥70, amber 50–69, grey below 50.

Revenue & earnings trend

Growth Quality ⓘGrowth is valuable only when reinvestment earns attractive returns (Aswath Damodaran): sustainable growth depends on return on capital, reinvestment and efficiency. Basis: total company revenue over the periods shown on the cards (3Y/5Y/all years), not per share, so a merger can show up as a growth jump; per-share earnings growth is in the value-creation card. 32/100
The company is growing, but growth may require heavy reinvestment or weak cash conversion.
Revenue growth 1 year
−13.0%
Revenue growth 3 years ⓘMeasures the company's TOTAL revenue from reported annual statements: compound average growth per year (CAGR) from the fiscal year 3, 5 or N years back to the most recent comparable fiscal year. Not per share: buybacks do not change this number, and a merger can appear as a growth jump. Per-share growth (which does include buybacks) is in the value-creation card.

Every model gets the same audited fundamentals; the result is the weighted average of 2,327 KRW, with the spread shown as a cautious and an optimistic scenario.
Is it still worth investing in stocks now?
The global stock market currently sits 15.5% above its aggregate fair value. Yest Ltd itself currently trades above fair value. An expensive market is no reason to stay out and no reason to buy everything at once: keep a broad savings plan running, buy single stocks only with money you can do without, and hold part of your money liquid while the market is high. The full picture including sectors is on is it worth investing now.
What is the share price of Yest Ltd (122640)?
The closing price on Nov 5, 2026 was 20,500 KRW. Our model-based fair value is 2,327 KRW, about 89% lower (overvalued). We carry closing prices from our data provider, not a live tick.
What should I pay attention to with Yest Ltd right now?
The price sits above even our optimistic bull case (3,420 KRW). The favourable scenario is already priced in. Weak quality (30/100) 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.
