FidelityÂ® Defined Maturity Funds. Defined Maturity Funds (DMFs) are an innovative way to invest in municipal bonds. Like Fidelity's other municipal bond funds, DMFs offer professional management, diversification, and seek to provide federally tax-exempt monthly income. They can also be sold at the end of each business day at their net asset value.
What they are. Liquid funds are simply debt mutual funds that invest your money in very short-term market instruments such as treasury bills, government securities and call money that hold least amount of risk. These funds can invest in instruments up to a maturity of 91 days.The maturity is mostly much lower than that.wo, unlike other funds, the NAV of liquid funds is not volatile as the only change in their NAV is mostly as a result of the interest income that accrues. In other words, given their short-term maturities, these instruments are hardly traded in the market.
