An unusual investment approach has helped a fund manager make billlions: His back tells him when it's time to sell by acting up. "I used the onset of acute pain as a signal there was something wrong in my portfolio," he once complained. "I rely a great deal on animal instincts." What the financier's back might be reacting to is shifting market patterns that the intuitive part of his brain has absorbed.
Sorry I can't get what the man wants to sell and the meaning of the underlined part - shifting market patterns.
He's a fund manager, managing people's money through buying and selling stocks and bonds and other investments.
The financial markets are always shifting. They are never stable. A good manager knows what to buy and sell and when, by being able to read the patterns in the market.
