What moves the price
The last reported earnings sit well below what analysts expect (earnings in transition, for example after write-downs or an earnings dip); whether the stock is cheap or expensive hinges on the expected recovery actually arriving. Read the fair value with that caveat.
The share trades about 1% below its 52-week high and 129% above its 52-week low, currently above its 200-day average.
For context, the median of 10 Healthcare peers we cover trades at −7% fair-value upside, at −3%, JAZZ screens cheaper than that median.
