Bailing and getting back in makes no sense unless you're a fortune teller. You pay almost 2x in taxes with that day trader mentality. Apple fell from $200 to $80 not too long ago and bounced back strong to $700. Along the way, they had a couple of big drops. You can't predict these things. I agree you shouldn't hold a stock based on blind faith or love, but the last thing people should do is panic. In fact, the best time to make money is when others are panicking.
For those who are long Apple, take a deep breath, examine the facts, and make an informed decision. In my mind, now is a good time to get in, not out for several reasons:
1. There's a good possibility that China mobile and NTT DoCoMo will carry the iPhone this year. That's about a billion more people who'll have access to the iPhone.
2. Strong product pipeline: iPhone 5S, iPad mini 2, iPad 5, next gen iOS and Mac OS and possibly an Apple TV.
3. Robust demand. Apple left billions on the table because they couldn't reach supply/demand balance for quite a few products: iPhone 4, iPhone 5, iMac and iPad mini.
4. They're growing. They grew by double digits YoY but people were disappointed by next quarter's guidance. What many forget is that unlike last year, Apple won't have a new iPad launch, and yet they're still expecting to grow 5-10% which is very impressive.
5. Cash. They just added over $16B to their cash pile, which is enough to buy Nokia based on their current market cap.
