Yes, you can, but u got to short a little at a time. At each $1 interval, short 100shs. So if u started at $60 you know have 700 shs short with a cost basis of $63.50. It has gone up $10 in 9 straight days. But u know what, it might only take 1 day for it to trade down $10. Think stock BUBBLE and be careful to the upside. But when this PIG goes down, its going down hard and fast with a P/S ratio of 7.98.
