Either the brokers or the sellers of the shares to the brokers, are bound by law to cover. Most of the time, the issue never gets pushed far enough where Law forces them to cover. This, because 99.99% of the shorted comapanies are then so broke, no attorney wants to fight the matter, nor are these companies able to afford to uplist. A symbol change doesn't do any good, I believe, because all the broker does is change your/our cybershare's symbol, since no certs were ever issued in the first place.
Wilshire realizes the very unique position that HMGP is in, being debt-free with very considerable independantly proven and probable reserves and heavily naked shorted.
What would happen if an MM is forced to cover a boatload of cheap shares at a multi-dollar price? One of two things: They would file for bankruptcy protection, or they would cover. Now, considering that it appears NITE is the culprit in the NSS matter here, and that NITE is a BILLION dollar corporation, I kinda doubt thay'll be able to skate with bankruptcy protection.
Also remember, the lower they take the pps, the more shares NITE will be able to recover on the way back to $1.00-$2.00.
There will ALWAYS be sellers. "Every man has his price"
