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. PTC Therapeutics 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 PTCT has traded between $58.80 and $90.87. Today it is 31.7% below that high and 6% above its low.

On the business: revenue grew 114.5% year over year; net margin is 39.4%.

Its beta is 0.55: it tends to move less than the market.
