The hedge fund industry has grown to nearly $3 trillion over the last 20 years. High-net-worth individuals and institutional investors expect high returns and low correlation with traditional asset classes in exchange for the fees paid. The standard fee structure is “2 and 20,” 2 percent of assets under management and 20 percent of profits, representing high fees for active management. Hedge funds are largely unregulated and somewhat mysterious. As a result, they are the subject of debates and controversies among market participants and policymakers alike. Debates focus on fee structures, alpha versus alternative beta, weakening returns, activist investors, and leverage. The Securities and Exchange Commission has targeted hedge fund misconduct and malfeasance, pursuing perpetrators of fraud, insider trading, and conflicts of interest in the industry. Several high-ranking Wall Street hedge fund executives have been charged with, and in some cases convicted of, breaking securities laws.
