Apple is up 100% because it's kind of the safe haven among tech companies. It actually has the earnings to justify its market value even when using conventional P/E ratio evaluations. This means that if the current oversupply of "fantasy" in the stock markets, especially the tech markets, should ever run out, Apple will most likely be much less affected than most other companies.

Lots of tech-interested investors realized this and decided to take some of the gains made with more risky bets into this "safe haven", because this lets them continue to invest in a tech company at least. And that's why the stock is up regardless of any new groundbreaking product from Apple.
