It's called "rotation". It's one of Wall St's typical games .... bash and drive down a stock to a given point, then some money people begin to move in; then, send out a couple of analysts to reinforce the stirrings; then the media begins to post some "good news" .... etc. etc.
Everybody already knows that Apple will be coming out with new iPhone products. But NOW, suddenly, it's "NEWS". etc. etc.
that's the gist of it.
