Chase Coleman's Tiger Global Management LLC in New York, which was backed by Robertson, returned 71 percent after fees, fund investors said. John Griffin, the former Tiger Management president who oversees $7 billion at New York-based Blue Ridge Capital LLC, posted a 65 percent increase. Tiger alumni including Lee Ainslie, Andreas Halvorsen, Paul Touradji, Stephen Mandel, Bill Hwang and Chris Shumway showed gains last year ranging from 27 percent to 51 percent, said investors, who asked not to be identified because the returns aren't public. The average stock hedge fund rose 10.7 percent last year, according to Chicago-based Hedge Fund Research Inc. ``Across the board the Tiger Cubs were some of the best- performing funds last year because they've been able to provide two-sided alpha,'' or gains on both rising and falling stocks, said Ted Wong, chief investment officer at Constellar Capital LLC in New York, which farms out money to hedge funds.
