You know what often gets overlooked? The intrinsic value Enron had. Now we all know that their accounting practices were a little on the gray side, but it was politics that brought them down (well and the legal system and stuff). But some people laughed at my dad for buying Enron and I think that's kind of mean to say the least. They had a functioning company and they could have made lots of money. Same exact story with AIG. Lots of intrinsic value. I lost 10k on that one, but they are still running and I'm going to let my $300 or so worth of stock rise. It might take 30 years, but I'll get my money back.
So I see some similarities here. Like we have some sort of kooky accounting, no response from management, a lawsuit or two... but underneath all this they make money. And the only thing that could stop them is going to jail or getting delisted or restating earnings as 8 million instead of 41 or if people decide their product really is just "snake oil".
