People who bought the stock planning to dump after an iPhone pop are selling. It is actually good to wash these people out.
Also, AAPL is the best stock I know, over the years, that has gotten cheaper, AS the price has gone up. Get your head around that one!!
The market is pricing in a lot of negativity here. Put it this way- if the market collapses and the world goes to hell, your $2000 is not going to be worth much anyway so you might as well put it to work in AAPL. If the world doesn't end, then boo-yaa!! See, win-win.
