Fernando, FYI. SIAF has been continuously shorted over the past year-and-a-half. Looking at the available short volume on Interactive Brokers would tell you this.
Currently, there are no available shares for shorting on IB, meaning they're maxed out. How many this entails, I remember the available number at one time being 350,000. So use your best guess on this one.
Not saying there isn't other inventory out there, but the market action over the last few days tells me that there are a number who were hoping for a drop to cover; possibly shorting the max to drive it down.
So, shorting might happen after the "Sweden Visit Pop", but there are a lot outstanding right now that are hoping to cover before this ever happens.
