If you look of how AAPL trades, you will notice that this is nothing new. AAPL can easly double in a matter of few weeks. Just wait for a new line of products to hit the market. I see AAPl $800 by end of June.
it would be nothing new if Jobs never left. But fact is, it is now Cook, so it is totally new. I wouldn't use apple's historical performance under jobs and think it can repeat itself with cook. i don't even think Cook is going to be around in 12 months.
