"A hedge fund is just a fancy name for an investment partnership that has freer rein to invest aggressively and in a wider variety of financial products than most mutual funds. It's the marriage of a professional fund manager, who is often known as the general partner, and the investors, sometimes known as the limited partners. Together, they pool their money into the fund." — Investopedia
