Stock has taken out key support and the damage has already been done due to weak hands that should not be in this stock. This means that the street believes this will go below $400, even though it is way too cheap. Don't fight it. Let it come in and buy at lower prices. Shorts and weak hands are in control.
I don't consider it over done, a projected 20% in operating income year to year is a big deal, more so when no guidance is given for Q4. If they thought they could guide q4 positive they would have. Apple is a waste of time & money at these levels.
