In half of the simulated outcomes the price ends between ₩77,230 and ₩112,062; in 9 out of 10, between ₩55,522 and ₩155,874. Estimated annual volatility is 117%.

What this means
These are two different questions: fair value looks at the business (what it is worth given what it earns) and the odds look at the price over the next month. Tesna sits below fair value and its odds of rising over a month are somewhat worse than a coin flip. An expensive stock can keep climbing and a cheap one can keep falling, which is why ATLAS shows the two readings separately.
Over the last 52 weeks 131970.KQ has traded between ₩40,500 and ₩196,900. Today it is 50.7% below that high and 140% above its low.
Its beta is 1.12: it moves roughly in line with the market.
