Sell Apple?

It was a question I asked myself after Apple Quarter 3-2011 Earning Report. I think Apple will have a good earning in next few year? Should I sell on the news, take profit, and buy back later as I did last time?

What if I cannot buy it back? Apple continue move up or never come back to the price I sell. I made a mistake with Costco, Target and many good stock.

So, back to the basic. Why I bought Apple? Was it a trade or an investment?

Buy Back Apple

Last Friday,when market down, I had a chance to buy back Apple. I sold it couple weeks ago to take profit. Since Apple is a good company, I followed it to see a change to buy back again. Yeah! This time, I bought it less than the last time I purchase it. I was so happy. Should I keep it for long term?
