ATLAS estimates United Microelectronics's fair value at about NT$116.10 per share (reasonable range: NT$72.59 to NT$185.67). At NT$122.50, the stock trades within 8% of that figure: close to fair value.

It is calculated with a blend of a discounted cash-flow model and peer valuation multiples. Confidence in the estimate is medium. It is an estimate, not a promise: if the company's results change, so does its fair value.

ATLAS's model gives United Microelectronics a 48% chance of finishing higher a month from now (21 trading sessions) than today: close to a coin flip.

In half of the simulated outcomes the price ends between NT$110.30 and NT$134.03; in 9 out of 10, between NT$92.80 and NT$159.30. Estimated annual volatility is 60%.

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. United Microelectronics sits close to 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 2303.TW has traded between NT$43.80 and NT$185.50. Today it is 34.0% below that high and 180% above its low.

On the business: net margin is 33.3%; it trades at 19.6 times earnings.

Its beta is 1.71: it tends to move more than the market, both up and down.
