单项选择题
Which of the following statements about duration is FALSE （）
A. There is a direct relationship between yield to maturity and duration.
B. There is an inverse relationship between coupon and duration.
C. There is a direct relationship between duration and maturity.
答案
参考答案：A
解析：
Bonds with longer maturity have a higher duration, all other things the same. Bonds with larger coupons have a smaller duration, all other things the same. A zero coupon bond has an effective duration equal to its maturity. Duration measures the approximate change in price given a change in interest rates. Therefore, the duration of the bond does not change with the yield to maturity of the bond.
