I think AAPL will continue to climb up until earnings, beat the estimates (as usual) but then drop immediately afterwards, as people take profits.
Then we'll see it slowly rise again as it approaches the fall when people get themselves into a frenzy over 3 possible new products announced before year end -- (a) iPhone 5 w/ a 3.96inch screen (b) iPad nano with a 7 inch screen and (c) aTV or iTV upgrade of some sort.
I don't think AAPL will drop back down to the 400s or low 500s soon. They seem to be laying even more foundation for controlling their whole supply chain in both hardware and software. Hardware as in building more manufacturing plants in china to pump out whatever they want in a short amount of time. For example, the whole 7 inch iPad rumor. If Google can make their tablet in 4 months, AAPL can do that in the same amount of time or shorter. While Microsoft announces a tablet and shows everyone, but then we have no idea when it will be released or pricing. Just seems really slow and clunky for MS.
As for software, they are continuing to take really useful 3rd party applications and then integrating it into their own iOS with their own product. Eliminating google maps was pretty shocking because it's such a useful product, but it's really smart if their own map app is just as good or better.
Not only are they controlling more and more of their own supply chain, they are constantly attacking other companies with use of their patents. The whole Galaxy Nexus ban just seems crazy. Like, they actually were successful in halting the sale of another Company's flagship product? It doesn't seem like they are playing fair.
Just some food for thought...
