Mutual Funds

A mutual fund is an investment fund that pools money from many investors in order to invest in securities such as stocks, bonds, money market instruments and other assets. They are operated by professional money managers who decide how to allocate the fund's investments in an attempt to produce gains. Mutual funds are often an attractive alternative for investors because of the professional management they offer. However, they are still risky enterprises.
