I didn't have a true naked short. I was long RSX and short TRF. It's still a good move, and I might even try to do it again starting Tuesday morning.
The 55% Premium will disappear. It's just a matter of time.
I did/can make money even when/if the Russian Market goes up -- all I needed/need is for the Premium to shrink (or even disappear completely, possibly reverting to the Discount that this Closed End Fund eventually has reverted to several times over the last 15 years -- see link to chart).
