New York | Australian hedge fund manager Greg Coffey says he no longer has the risk appetite he had as a younger trader, settling for a more narrow focus on fixed income where his job is to essentially forecast where interest rates around the world are headed.

Known as the Wizard of Oz for his trading prowess, the New York-based money manager founded Kirkoswald Asset Management and is estimated to be worth $989 million, according to the Financial Review Rich List.
