A special dividend may not prompt the cover, but it's going to sting those who hold an NSS position. The real killer will be if EIGH goes through with the possible quarterly dividend. If they do start paying a quarterly dividend, it will force a cover. It would be to EIGH's advantage to go with a quarterly dividend as this will drive the price of all their stock up into the multi-dollar range. There are a lot of people who hold stocks strictly for dividends, myself included, as they provide a nice income with no effort. Even with the recent share price reduction adding to the value, at this point a share shorted at 40 cents would lose half the gained value if the dividend is 10 cents. If it is more, you know... Anyone shorting this stock is currently betting that if the value suddenly drops by half its value that feelings of capital preservation are going to be overpowering, and they are counting on this to cover their shorts. If those holding will hold past the dividend and the coming cover, this strategy will fail and those with the vision and preseverence to stay with it will be very happy people.
EDIT - Thanks for that information PizzaClown, I heard that was the case too, and that the ubers are limited to 10 people at most to give personalized attention.
