Well-known investor Julian Robertson plans to put tens of millions of dollars into a global macro fund launched by Trient Asset Management, a firm co-founded by a former head of Norway's sovereign wealth fund, in a bet that the global economic rebound will fall short of investors' expectations.

The global macro fund, so called because it places bets on the direction of the world's economies, will open to other investors in the fall. One of the four funds within Oslo-based Trient's portfolio, it will invest with a bearish view.
