Hedge funds are private investment vehicles that aim to generate absolute returns regardless of market conditions. The hedge fund industry has grown significantly from $39 billion in AUM in 1990 to $2.5 trillion in 2013. Most hedge fund investors are large institutions that allocate a portion of their portfolio to hedge funds to reduce volatility and enhance returns. There are over 10,000 hedge funds employing a variety of strategies such as long/short equity, event driven, macro, and relative value. Top performing hedge fund managers have generated annual returns upwards of 20-30% over long periods of time.
