GilloD
before you get upset, allow me to clarify.
You are saying that investors selling off the stock today are undervaluing the company because of this short term news, and that you, GilloD, appreciate that true value of Apple is greater. This is pointless though, since you don't own the stock. The stock is of value to these investors as a way to make money, not to receive validation of their ability to assign value to corporations. Conversely, the ability to accurately assign value to corporations is entirely useless unless you use it to invest (or perhaps by selling your tips as an analyst etc).
Today is a GREAT opportunity to lock in gains, especially for those who agree with you! If they sell high today, the stock drops, they can make all those gains all over again by getting in on the floor when it recovers. There is nothing moronic about 'working' stocks like this, per se - it's only if you mistime the entry and exit points that you lose out. With swings like this though, it's actually relatively easy to make out big, because you have more margin for error. The dumb thing to do would be to hold onto your stock and wait for it to come back up. You haven't MADE any money there at all.
