1) His second month of operation, August-1998, he had a ~37% MONTHLY loss. This should have scared anybody away from ever, ever investing with him. 2) July-2002, a ~46% loss. Come on! His exit strategy is badly flawed. 3) October-2008, another huge loss. This guy likes to eat like a bird and dump like an elephant.
Yup! He explained that he tried to time the bottom on the SP500 in 2002... he then "learned' his lesson. Sounds to me like he tried it again. http://ljmpartners.com/content/PDFs/ActiveTraderMagazine.pdf http://ljmpartners.com/content/PDFs/ActiveTraderMagazine_part2.pdf This is where quantitative risk management gets you.
Risk management? These guys were selling naked puts I am amazed they can talk dumbass investors into paying 2/20 for their 'expertise' to short naked ES options. Fat tail events happens rarely, but when they happen they tends to wipe you out.
