Duration 1 1 year is more appropriate. According to the public information related to the query (1 plus 10) divided by 10 is equal to 1 1 year, so the annual interest payment is 10, so it is within1/year. The longer the duration, the more sensitive the net asset value of bond funds is to the change of interest. If the duration of the bond fund is five years, if the interest rate drops by 1 percentage point, the net asset value of the fund will increase by about 5 percentage points. Conversely, if the interest rate rises by 1 percentage point, the net asset value of the fund will lose 5 percentage points.
