FFGO - Those are the four that I have been tracking. If there are any others, since August 1, 2012, I will let you know.
I am sure these firms are well aware of the market manipulation NITE et al have been doing through short and distort.
Need an audit of all retail brokers to expose the truth. I would assume that the investment advisors for the brokers and market makers have been successful in getting some impatient and uninformed shareholders to take 100% losses. Those positions would likely be closed if an audit occurred today.
Would need to do a book audit of the brokers going back to August 2010.
