"With the exception of my 1975 to 1980 sabbatical, I have spent
most of the past 34 years in a quiet, secluded office, either in Wall
Street, upstate New York or aboard a large motor yacht, with trading
monitor, phones, technical studies and other accoutrements. Consis-
tently, my principal focus has been trying to make big profits on my
favourable positions and to avoid taking big losses on my adverse ones.
I have invariably played a lone hand, and very much by choice, having
learned the benefits of operating independently early on as a Merrill
Lynch account executive in New York in the 19605. The lesson that I
learned was this: it is not constructive to share trading ideas and market opinions with others, regardless of their opinions or presumed expertise.
The uni\[§verl truth on Wall Street is: ‘Those that know don't tell; those
that tell- dct know.‘"
