After the company's recent fall from grace, Amicus (FOLD 2.12%) shares are showing new life, up double digits in late-day trading. Today's pop follows a press release announcing solid phase 2 results for one of Amicus' pipeline drugs. On the other side of the coin, today's biggest loser was a company called Accuray (ARAY -0.38%), a medical devices stock down some 20% today after pre-announcing quarterly results last night after the market closed.
