The 2.5MM you refer too was not ML but one of the brothers(the weakest trader).It is an amazing feat to win 10 out of 11 sessions,month after month.

ML made considerably more.One man,no research assisitants etc.We traded with the biggest banks in the world.ML "picked them off" all the time.

They had teams of players and analysts and all the trappings.

Sorry no comparison between ML and Buffet.
