The fund's management tries to maintain the value of each share in the fund at $1.

Unlike bank money market accounts, money market mutual funds are not insured by the Federal Deposit Insurance Corporation (FDIC).

However, since they're considered securities at most brokerage firms, they may be insured by the Securities Investor Protection Corporation (SIPC) against the bankruptcy of the firm. In addition, some funds offer private insurance comparable to FDIC coverage.

Tax-free money market funds invest in short-term municipal bonds and other tax-exempt short-term debt. No federal income tax is due on income distributions from these funds, and in some cases no state income tax.

While taxable funds may offer a slightly higher yield than tax-free funds, you pay income tax on all earnings distributions.

Many money market funds offer check-writing privileges, which do not trigger capital gains or losses, as writing a check against the value of a stock or bond fund would.
