Amatuer (in French amatuer roughly translates as "killer of love" as opposed to amateur = "lover of" but that's neither here nor there) I get your general premise that "the market" usually knows best, and that if a company like CTIX shows little SP appreciation despite reporting good progress, then "the market" must know something better than I might as an individual investor. That general premise falters a bit when considering the occasional broad market decline or crash that comes along periodically, and that no one, including "the market", saw coming. More to the point, if the market always knows best and puts its value appropriately on individual companies at any given time, then why would PCYC be valued by the market at $5/share in Feb 2011 and then give it a value of $25 a year later? How did the market miss such a discrepancy? In REGN's case, the market obviously missed that a stock that could be bought for $13/share in 2009 would be worth $575/share 6 years later. What changed in both cases of course was that the science kept moving forward, partnerships were formed, cash was more plentiful, etc. I simply don't buy that the market always knows best, especially about CTIX. In fact I'm betting heavily that in the isolated case of CTIX, in fact I know quite a bit more than "the market" does. My 2 cents.
