The volume spike that occurred friday is a strong bearish signal in my opinion. I will open a short position if the price breaks through the 46.60 level. There will be a potential support level at 44.45 but I think we will see a retracement to the 0.618 fib level around 43.
Entry: 46.28
TP: 43.12
SL: 47.51
R=2.5
Good luck.
