From what I have read, two people who invested at the height of the bubble and got killed made the complaints in 2008.
If every one of his clients got anally raped, I would think he would have lost all of his customers no?
If you are going to sit it out, than thats totally cool.
From what I read, his fund as a whole lost between 40-80% of its AUM in 2008. Now I don't know how many people/companies invest through his firm, but that's a huge knock. Most fund managers are out on their ass when they report losses like that at a firm like, say, Citadel or RenTech.
The guy may be a financial wizard and predicted the collapse coming, but why didn't he mitigate his risk? Other funds and firms did.
