Speculating a little here.  Buying the dip, grabbing this one off of support, as it is selling off on lower volume.  anticipating a potential breakout around 110.  Has a lot of support around 100, and I think it has potential to make a big move to the upside, especially if market rallies strong and it breaks 110 on volume.
If it doesn't, I own puts on MSFT, which looks like it might be breaking down here.
I may add DEC or JAN calls if it breaks 110.
