Bond Fund

What Does Bond Fund Mean?
A fund invested primarily in bonds and other debt instruments. The exact type of debt the fund invests in will depend on its focus, but investments may include government, corporate, municipal and convertible bonds, along with other debt securities like mortgage-backed securities.
