Money continues to pour into alternative investments, which more than doubled in size from 2005 to 2014. These investments’ global assets under management grew at an annualized pace of over 10 percent; that’s twice the rate of traditional investments. It wasn’t just one niche that grew, like real estate or private equity; every alternative asset category grew. On the other hand, alternatives have enjoyed this growth at a time when their returns have generally lagged behind traditional market indexes, like the S&P 500. Why is this shift away from traditional investments occurring, particularly among pension funds and endowments? Will this trend continue, or reverse? What are the implications? We’ll provide the answers.
