I wish the SEC would make it illegal to naked short stocks and then enforce it. I don't know if it has been naked shorted lately, but they did it before in this range. They had at least 12M failed to deliver shares in April. If somebody sells at .0055 or above we can always say that people are also bailing or taking profits. When it gets to .005, I guess it could be a bail, but it seems less likely to see anybody sell at that price. I'm sure there are plenty of people who would buy there, but to sell seems like something a normal person would only do in an emergency.
Playing with it is not a bad description. Not all that high of volume either. It is a figure a person or MM could buy back up quickly if need be.
The MM's are supposed to create a market or facilitate/regulate trading in a stock. That includes naked shorting. I'm don't think I like how they have handled HFBV.
