AAPL died with Steve Jobs. It's been a zombie since then and it is becoming apparent to the rest of the world now.
At 538, that seems a bit harsh IMO.
AAPL in the mid520's has looked to me like an attractive bottom. Very close to where we are. Going into the Christmas season, AAPL on the downturn with IPad Mini and iPhone5 appears attractive. AppleTV is on the horizon. Seems another great opportunity. For the last year+ I've been a product fan, but not a stock buyer. I'm on the cusp!
Facebook is a similar situation. Blew it off since the IPO announcement. The IPO was a historic disaster. Just terrible.
But the stock has fluctuated in a trading range since August. Now once again at ~20 it's starting to at least attract trading range incentivization, and maybe long term positives.
