Money-market funds resemble savings accounts. For every dollar you put in, you get a dollar back, plus the interest your money earns from the investments the fund makes. Since these funds are usually price-stable, some investors prefer them to stock or bond funds. But the interest the funds pay is low when interest rates are low. In some cases, money-market funds let investors write checks against their accounts. There's usually no charge for check-writing although there may be a per-check minimum.
