the biggest thing is to watch volume, not price
we know they are at least ~ 30 MM shares short
if the price shoots up to your predetermined sell price, but you see the volume is only 1.5 MM a day for 2 or 3 days, you can be sure you are selling too soon
i am also apt to run numbers in my head about sell prices, and i constantly have to remind myself to not worry about the price as much as the volume
the price WILL go up, and whether it's 5 bags, or 7 or 10, it's all profit
