They have during the past year, but now does not seem to be the right time to short.. There is 28,000 shares short and best case scenareo for them is CUU drops to zero. That would still only be a gain of $28000 before commish. On the other side, CUU can shoot up very quickly without any warning, and they could easily be stuck buying back in at $3-$4 easily.
The BFS will come at any time and the buy out may accompany it or follow it soon after.
The way I look at it, there is no money shorting a $1.00 stock unless you are going to play with alot more than 28,000 shares
If the shorters are making money, good on them but I know that I sleep much better at night as a long CUU investor than I would if I was short.
