can't blame on manipulation...the fact is there are many idiot home gamers who are clueless, just to dump stocks on good earnings...and chase stocks that have no earnings...it is true.
example? why did they dump abbv after good earnings? why did they dump alks today? and celg...the growth story is still in tact...
which is a good thing. we need them in the market
and complained about drug companies charging too much? go rot in hell
