Mlsoft- I think its more a function of the large short position and the fact that they got a one two punch here today.. A simple equation of too many people betting on one direction, and that spells a recipe for sharp movement.
I agree with you on the DELL news as to how it pretains to the industry, but certainly dont think the optomism is overdone.. It simply caught alot of folks off guard, and that can feed on itself..
