Money Market Mutual Fund

Also called: Money markets, money market funds

What is a money market mutual fund?

Money market mutual funds own short-term investments like Treasury bills, government securities, and certificates of deposit, or CDs. Many investors hold cash in these mutual funds because they're considered safe investments. They’re not FDIC-insured, so there's no assurance losses can be repaid.
