Master the Money Market
This very-short-term credit market fuels two common savings vehicles.
The money market is a collective name that describes all the different ways in which governments, banks, corporations and securities dealers borrow and lend money for short periods.
The funds' managers, who decide which money-market instruments to buy, charge a modest management fee, on the order of 1% or so. All that makes the funds liquid, convenient and relatively economical to own.
