You've heard this story before: A trader at a bank is knocking the cover off the ball. His success garners political power within the bank. He creates a fiefdom that insulates him from the rest of the firm; his trading group explodes in size. He lives a conspicuous, extravagant lifestyle. His ego alienates the management and intimidates the support staff. Then the trader hits a rough patch. He uses all the tricks in the book to keep his poor results under wraps while he tries to find a way to recoup. Everyone is gunning for him, so he has to get back into the black, and fast.
