well, what i see it as is a combination of:
-> normal short covering / lottery playing of eventual worthless stock...short covering (at 30c) from those who were short from much higher and figure why hold on any longre?
-> unable to short exc. through puts; (which i got a bunch of today) or through FNA. normally, smarter people are able to short the common, unable with recent 'no shorting!' rules.
check out the action between 10:15 and 10:45 ; on these cheapies, that's textbook high % top setup.
normally, any cheapies that are long-since-known to be 'worthless' have double/triples from their lows. that's nothing new...
