An expensive but tasty Apple

Apple Inc.(AAPL) is on fire. The stock just passed the $140 barrier and some analysts say that they see over $200 in the near future. $200 may be a bit much, but I agree that the stock is going higher. Momentum players will ensure that. If you're a value investor, then this company looks awfully expensive(45x earnings, nearly 10x P/B). You're probably not going to want to go near it, EXCEPT, its PEG is 1.76. That's not bad at all for a company that's nearly doubling earnings year over year and selling the hottest product on the market.
They announce earnings on July 25th and everyone is expecting them to crush the estimates. If you've already been in the stock for some time, then you've made some terrific gains and should sell into the good news. If you're looking to get into the stock, I'd wait for a pullback of some kind before pulling the trigger.
