A mutual fund is a professionally managed Medium or vehicle that pools money from many investors and invests it in stocks, bonds, short-term money market instruments and other securities.Its fund operated by an investment company which raises money from shareholders and invests in a group of assets, in accordance with a stated set of objectives. mutual funds raise money by selling shares of the fund to the public, much like any other type of companycan sell stock in itself to the public. Mutual funds then take the money they receive from the sale of their shares (along with any money made from previous investments) and use it to purchase various investment vehicles, such as stocks, bonds and money market instruments. Inreturn for the money they give to the fund when purchasing shares, shareholders receive an equity position in the fund and, in effect, in each of its underlying securities. For most mutual funds, shareholders are free to sell their shares at any time, although the price of a share in a mutual fund will fluctuate daily, depending upon the performance of the securities held by the fund. Benefits of mutual funds include diversification and professional money management. Mutual funds offer choice, liquidity, and convenience, but charge fees and often require a minimum investment. A closed-end fund is often incorrectly referred to as a mutual fund, but is actually an investment trust.
