On CAPS, 24% of the 132 members who have rated Affymax believe the stock will underperform the S&P 500 going forward.

Earlier this week, one of those bears, All-Star TSIF, touched on the stock's seemingly unsustainable valuation:

I suspect the share price and the drug sales of Omontys will be rather ANEMIC in the ... short run.

Overall ... approval of Affymax's injectable drug Omontys, once [monthly] for those with kidney disease, should be lower cost than the monopoly drugs currently on the market.

The rise in share price prior to the announcement pretty much values Affymax [fairly] for now, especially with the split that will go to [Takeda Pharmaceutical]. ... The road to production is generally long and those investing in FDA catalyst drugs are generally not loyal.
