OK, this guy took 11,000 to 18,000,000 in 18 months in the bull market of 1999/early 2000. This gives us a monthly compounded rate of 51%, or annual multiplier of 138 fold. That reminds me of a stock that rose 500 times in one-year period at that time, called Excelera (XLA). It rose 500 times between March 1999 and March 2000 (The stock is no more quoted, but if you look for historical information, you should find it). Such was the craze of those days. Adding margin of course boosted those returns enormously. Does not take away from his performance. But it is good to know the period in question.
