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. Castellum 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 CAST.ST has traded between SEK 100.25 and SEK 137.30. Today it is 2.7% below that high and 33% above its low.

On the business: net margin is 26.9%; it trades at 23.9 times earnings.

Its beta is 1.44: it tends to move more than the market, both up and down.
