SS- on LNTH- maybe yes, however
in general, I strongly believe that playing an in demand sector is the way to go. Of course I believe in the fundies, but I believe in staying away from bad sectors, regardless of valuation, and being in sectors that are doing well. Having said that, there are also some non cyclical sector stocks that are almost always a buy if the valuation is low vs their peers.
SS, all I can tell you is, I have done extremely well through the years mainly playing momentum, and in fact just hit a new all time high, and am up 23% for the year(on my stock portfolio). You know SS, maybe there's more than one way to skin a cat ?
