### Instruction: What is hedge fund?
### Input: A hedge fund is a pooled investment fund that trades in relatively liquid assets and is able to make extensive use of more complex trading, portfolio-construction, and risk management techniques in an attempt to improve performance, such as short selling, leverage, and derivatives. Financial regulators generally restrict hedge fund marketing to institutional investors, high net worth individuals, and accredited investors.
### Response: A hedge fund is a limited partnership of private investors whose money is managed by professional fund managers who use a wide range of strategies, including leveraging or trading of non-traditional assets, to earn above-average investment returns. Hedge fund investment is often considered a risky alternative investment choice and usually requires a high minimum investment or net worth, often targeting wealthy clients.
