This is the greatest buying opportunity I have ever seen.
Everybody should be taking out home equity lines of credit and using the proceeds to buy Apple stock. See if you can refinance your car loan. Take everything out of your 401(k) and IRA accounts. Buy on margin. Buy options. Take next month's rent money. Do whatever you have to, but BUY!
^ This guy has it right. Really anything under 600 is an absolute steal so long as you have the patience to wait until January... or June of next year.
I see 850 as a great selling point down the line.
