It is normal business on Wall Street - investors simply re-adjust AAPL stock from "growth" category to "value" one.
It is sad so many folks misses what was coming for many months, with plenty of early sell @ decent price opportunities along the way.
Some folks mentioned that Google is better because of it has better revenue sources - right...
It is all about growth of only one thing - THE PROFIT.
Google or any other rapidly growing company will get there sooner or later too and and its stock will get the same treatment as AAPL is getting now.
Something never change...
Well if its all about profit growth how do you explain Amazon (which was way up again on Friday). Apple has made more profit in one quarter than Amazon has in its entire existence as a company. Yet Amazon is up 47% over the past year. Unless Amazon is heading for a big fall too?
