Hell no! As I said here last summer when it was in the 300's, it is NOT overpriced. Wasn't then and isn't now. Look at pe ratio, peg ratio, margins, all the metrics, then consider the talent and know-how, the disruptive technology power in that company and the cult like following of its customers to its products. I see no reason to sell apple. Stocks go up and down, and I expect it might consolidate a bit here before breaking 600, but I don't see a reason to sell at this price. And certainly would be insane to short it, its like stepping in front of a freight train. The market itself is off to the races. You gotta let the winners run. But if you MUST short something there are plenty of better targets and certainly some overpriced names out there. But sometimes companies trade at a premium for a long time (witness the epic gorilla run in netflix which is probably still overpriced even after going down two thirds in price lol. The market stays irrational longer than u can remain solvent. But I don't think the flight into apple stock is irrational, personally.
