On CAPS, 18% of the 11 All-Star members who have rated Anthera believe the stock will underperform the S&P 500 going forward.

Anthera's share price is traveling at the upper end of recent range as the expected final interim efficacy analysis of the VISTA-16 phase III trial has failed to make its 2011 appearance. Of course, the analysis is only a little late which might just be due to administrative issues, but given the company's prior whitewash of results of the IMPACTS trial my expectations are somewhat dim.
