Just an opinion - people don't believe it yet - and the fact is, there is no proof that they have jumped through the last hurdle but Viropharma's infusion was compelling. Regardless, curing Alzheimer's or finding real treatments for it never seemed like a possibility, but Dr. Chain is a pretty good bet IMHO.
As for the stagnation, many are slowly accumulating at these prices while others periodically dump due to lack of patience or what they believe to be a better opportunity. Hope that doesn't sound too simplistic or contrite, but that's JMHO. GL.
