In half of the simulated outcomes the price ends between NT$176.57 and NT$218.64; in 9 out of 10, between NT$146.10 and NT$264.25. Estimated annual volatility is 64%.

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. SDI sits above fair value and its odds of rising over a month are close to 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 2351.TW has traded between NT$72.10 and NT$257.00. Today it is 22.8% below that high and 175% above its low.
On the business: net margin is 6.6%; it trades at 52.7 times earnings.
Its beta is 1.57: it tends to move more than the market, both up and down.
