A. The answer hinges on two metrics of a bond fund - its duration and yield.
Yield is straightforward, we will explain what is Duration below.
Duration measures a bond fund's interest-rate sensitivity. We all know if interest rate goes up, bond price does down. Duration measures the extent a bond fund's fall if the rate goes up. For example, a duration of 3 years means if the interest rate goes up by 1%, the bond's net asset value will suffer a 3% drop.
A good proxy of a bond's one-year return is its Yield - Duration. So if a bond fund's yield is 2.5%, its duration is 3, then you will likely see a -0.5% annual return.
