Over on CAPS, 64 of the 103 members who have rated Hemispherx -- or 62% -- believe the stock will underperform the S&P 500 going forward. These bears include All-Stars TSIF and zzlangerhans, who are ranked in the top 1% of our community.

Just yesterday, TSIF brought Hemispherx's swine-flu-fueled price run to our community's attention:

Generally FDA rulings have hard dates and hard data requirements. The spike seems to be that some investors think they will get an early review due to their preclinical studies in pandemic vaccines. The FDA, however, has never been known to rush a drug to market.

In a pitch from one day earlier, zzlangerhans elaborates on the bear case:

I kept following it but thought that it would remain in the sub-1 club until the FDA put their boot down on Ampligen again, shriveling the share price and any prospects of continued financing. But here we are a week short of the Ampligen PDUFA [Prescription Drug User Fee Act] and the stock has quadrupled off their recent stable low of 0.4. A lot of smashed up baby bios [development-stage companies] have been doing this lately and are providing good red thumb fodder....

Dilutive financings of 16M and 18M completed with lightning speed as the share price rose prior to the 5/25 PDUFA. Think these guys have any confidence that they'll get approval? Obviously not or they'd wait until their share price was at 10 after approval to raise cash.
