The yield to maturity is:

B) the discount rate that will set the present value of the payments equal to the bond price.

   
C) based on the assumption that any payments received are reinvested at the coupon rate.

   
D) none of these answers are correct.

A为什么不对呢

胡老师

yield to maturity实际上是使得未来现金流量的现值等于目前价格的一个贴现率，而票面利息是用来计算未来利息现金流量的。比较coupon rate 和 discount  rate   就可以了
