Do they have inside information? (no) Do they monitor in real time sales at each store or the web?(no) Do they have an inside track on what's going on behind closed doors at HQ on innovation? (no) Do they fully understand the nuances of the Apple supply chain? (no) Do they know the China strategy plans? (no) Do they collectively know the big money plays trying to short this stock through a media blitz of self serving negative news (maybe)?
I think earnings will be impressive (opinion) and that may not matter since now so many have a vested interest in continuing to paint a doom and gloom picture..I don't think Apple is sitting idle - they are too busy innovating for the next innovation wave and other are waiting on the sidelines to copy.
I just know that inside information is illegal so I am making that far reaching assumption in saying "no". So when you take that out of the equation what you have left are a bunch of analysts whose day job is creating FUD based on each others second hand conclusions.
