Ultra-short bond funds are mutual funds that generally invest in fixed income securities with extremely short maturities, or time periods in which they become due for payment. Like other bond funds, ultra-short bond funds may invest in a wide range of securities, including corporate debt, government securities, mortgage-backed securities and other asset-backed securities. 

Some investors don’t realize that there are material differences between ultra-short bond funds and other investments with relatively low risks, such as money market funds and certificates of deposit. Specifically, ultra-short bond funds tend to have higher risks than money market funds and certificates of deposit (CDs).
