Honestly, I doubt he is doing anywhere near that trading e-minis. He averages into all sorts of positions. Hell, he is probably buying KCG hand over fist right now. I would bet that most of that income is coming from "investment" type trades and he makes some coin on the side trading e-minis. Just my guess. Not to take anything away from the guy. Everyone I know who has met him says he is sharp as a tack and comes across as a very astute trader.
