BEVERLY HILLS, Calif. (Reuters) - Hedge funds, following an extended period of low investor confidence and unspectacular returns, are poised to be great again, according to managers at a West Coast gathering of some of the world’s largest investors. “If you define it as generating returns that aren’t commoditized, that aren’t easy, by doing things that others are constrained from doing, then $3 trillion is just way too small,” Andrew Feldstein, head of BlueMountain Capital Management LLC, said in reference to the current size of the overall hedge fund industry.
