On CAPS, 27% of the 149 members who have rated Optimer believe the stock will underperform the S&P 500 going forward.

Just last week, one of those Fools, All-Star zzlangerhans, succinctly summed up the bear case for our community:

Optimer stock is weathering yet another quarter of disappointing Dificid revenues by floating the old "strategic alternatives " flag. Sometimes the sale happens, more often than not it doesn't. I remember that tactic didn't work out very well for [Savient Pharmaceuticals]. Dificid has been a confusing underperformer, given that clostridium difficile infection continues to be a crisis in the US health care system and the available therapeutics are clearly insufficient. Perhaps a larger pharma feels like they have the skills to make Dificid more profitable, but I suspect antibiotics are a relatively low priority for most of those companies. Even if a buyout does occur, I think it will take long enough that most of the short-term momo traders will get bored and exit.
