"Cooperation and conflict are two sides of the same coin; both arise out of man's relationship with his fellows. The larger the group, the greater the possibility of development through cooperation, and the greater the possibility of conflict."

That was how a Salomon bond trader thought: He forgot whatever it was that he wanted to do for a minute and put his finger on the pulse of the market. If the market felt fidgety, if people were scared or desperate, he herded them like sheep into a corner, then made them pay for their uncertainty. He sat on the market until it puked gold coins. Then he worried about what he wanted to do.
