People have tried to compate the cost-benefit of MMs coming up with the dividend vs. covering. I think its more that that. When the transfer agent does an audit, most probably they would also be able to find out which MMs are into Naked shorting. Considering that NSS is illegal, I think this is like a indirect threat to the MMs. That's just my thought. Could be completely wrong though. But which MM would like to the threat of a SEC probe? They would rather cover the shorts at whatever price that may be, and never look back at EIGH. Which means, dont give your shares easily. Let them scramble like mad.
