MCK closed at 318.18. MCK presents an interesting short oppourtunity after putting in a potential topping pattern at 320, near the 1.0 fib off of it's monthly move. MCK can break below 317.43, then move to test 313, and more likely 302. MCK has been extraordinarily extended, and is ready for a larger pullback. If MCK can clear 322, I would avoid puts.
