thing is, they aren't nearly as leveraged to AAPL as the others because their revenue streams are more diversified. good for the long-run of their business, but from a purely trading standpoint, maybe makes it less directly attached to AAPL.
Sigmatel (SGTL) reports on Jan 25. Look at a 60-min or hourly chart (or longer) and it appears to have run out of steam and begun its rollover. I think people too quick to reposition for a serious downdraft will get tested on all these kinds of charts. Getting short too soon, IMO, will get you a big lick of pain before the reward.
(I know you don't short, I'm speaking generically to the board with "you")
