Hi Benji,

It's not perfect, but it's in a long-term down-trend, and therefore shortable. The stop would have to go above 100.71, so this may not be an ideal place to go short from a risk/reward perspective, but not all stocks will give you ideal trade setups. You'll have to do your own risk/reward calculations and decide whether this trade is acceptable to you at this time and at this level.
