By disgruntled shareholders, I take it it'd have to be one of the insiders to spearhead any litigation. Doesn't look like any of us garden variety shareholders are going to do anything on their own. You will recall how everyone was up in arms shortly after all this came down, but it fizzled pretty quickly. A law firm specializing in class actions might be willing to take it up for the customary contingent fee, they could initiate it on their own using boilerplate language, all they would need would be a name plaintiff. These class actions typically settle, without going to trial. Having said that, where would any money come from? BTW I noticed that Schwab no longer shows the CUSIP for some reason.
