One account out of a great many that he was managing did well, and he lost over 6M across the remainder of the accounts ! Not quite so impressive when you look at the reality.
The following is taken from a thread on elite trader:
"In July 1988, the Larry Williams Financial Strategy Fund was launched, followed in March 1989 by the World Cup Championship Fund, managed by Larry Williams, Jake Bernstein and two other “traders.” The 1988 fund lost more than 50% of its clients’ equity in barely one year, as reported in the October 1989 issue of Futures magazine. The 1989 fund also lost more than half of its original equity by May 1990.
So, Larry tried at least 3 different times to manage client money with surprisingly disastrous results. These are facts."
I dont think Larry Williams stands up to scrutiny.
