Money Market Mutual Funds

A money market fund is a mutual fund that invests solely in money market instruments. Money market instruments are forms of debt that mature in less than one year and are very liquid. Treasury bills make up the bulk of the money market instruments. Securities in the money market are relatively risk-free.

Money market funds are generally the safest and most secure of mutual fund investments. The goal of a money-market fund is to preserve principal while yielding a modest return. Money-market mutual fund is akin to a high-yield bank account but is not entirely risk free. When investing in a money-market fund, attention should be paid to the interest rate that is being offered.
