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. Constellium SE Class A sits below 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 CSTM has traded between $14.62 and $36.99. Today it is 36.7% below that high and 60% above its low.
On the business: revenue grew 15.2% year over year; net margin is 3.3%; it trades at 6.1 times earnings.
Its beta is 1.55: it tends to move more than the market, both up and down.
