Mark Weinstein-High-Percentage Trader After a brief period as a real estate broker, Mark Weinstein became a full-time trader. His start in trading was
so naive that he virtually threw his money away. After that early failure, Weinstein withdrew to seriously study the
markets and earn another trading stake. With the exception of one disastrous trading experience, Weinstein was a
successful trader from that point on. He has intensively traded a wide variety of markets, including stocks, stock
options, stock index futures, currencies, and commodities. Although he is reluctant to divulge specific details, it is
clear that he has profited handsomely in all these trading arenas.
I met Mark Weinstein through a mutual friend. Although he was very intrigued by the project, his desire for
anonymity made him reluctant to tell his story. He would call me and say, "OK, I will do it, let's schedule the
interview." Then the next day he would call and say, "I changed my mind. I don't want the publicity." This pattern
was repeated several times, with each decision accompanied by lengthy phone conversations regarding the merits
and drawbacks of doing the interview. Finally, in exasperation, I said, "Mark, we could have done three interviews in
the time we have spent talking about it." That was our last conversation regarding the matter until about two months
later when, impressed by the caliber of traders who had agreed to participate in this book, Weinstein decided to do
the interview.
Weinstein met me at my office one summer evening. Because the building turns off the air-conditioning after
5:00 P.M., we were forced out into a corner lobby, which, although warm, was at least less stifling. The interview was
conducted over a dinner of deli sandwiches and soda. Through our phone conversations, I knew Weinstein had a
strong tendency to go off in many directions in any conversation—that's how his mind works, one topic leads him to
think of five others and their various interrelations. Dreading a mammoth editing task, I stressed to Weinstein the
need for remaining focused on the specific questions. I could tell that Weinstein was making an extra effort to heed
this advice. This fact notwithstanding, the interview lasted five hours and yielded a 200-page transcript.
