Our Recommendation

Though sales of the company’s key product Ampyra have improved in the past few quarters, it remains to be seen whether the performance is sustainable. Moreover, we remain concerned about the company’s dependence on Ampyra for growth. We prefer to remain on the sidelines until we see a sustained improvement in Ampyra’s performance. Thus, we maintain a Neutral recommendation on Acorda. The stock carries a Zacks #3 Rank (Hold) in the short run.

Pharma stocks that currently look attractive include companies like Allergan ( AGN - Analyst Report ) , AstraZeneca ( AZN - Analyst Report ) and Novo Nordisk ( NVO - Analyst Report ) . Each of these companies carries a Zacks #2 Rank (Buy).
