Look, we all know who HH is, and he wouldn't still be here if he wasn't sweating bullets.
There's a lot to be worried about if the losses before covering are unlimited. I can lose my entire investment. He can lose the amount per share over what he shorted x the number of shares he shorted. That's an unlimited amount of money, depending on what the SP rises to.
That could be an absolutely astronomical figure.
My posts are backed by the fact that I've been in the corporate accounting world for roughly 25 years, and I refuse to let someone come on here and mislead SPNG shareholders.
