So some big funds are adding to or establishing positions, at these lowest in a year prices. If you're right there were only big block purchases and not sales today. It makes sense for the long haul. Where else can you buy a company trading for little more than 2X the Cash it will have by year-end 2013 (estimated $190 billion by then).
Don't forget Apple can make 5 - 10% per year just on its Cash invested in securities.
