请问

NO.PZ2016031001000075

问题如下:

The annual yield-to-maturity, stated for with a periodicity of 12, for a 4-year, zero coupon bond priced at 75 per 100 of par value is closest to:

选项:

A.

6.25%.

B.

7.21%.

C.

7.46%.

解释:

B is correct.

The annual yield-to-maturity, stated for a periodicity of 12, is 7.21%. It is calculated as follows:

PV=FV(1+r)NPV=\frac{FV}{{(1+r)}^N}

75=(100(1+r)4×12)75={(\frac{100}{{(1+r)}^{4\times12}})}

10075=(1+r)48\frac{100}{75}=(1+r)^{48}

1.33333 =(1+r)48

[1.33333]1/48 = [(1+r)48]1/48

1.3333302083= (1 + r)

1.00601 = (1 + r)

1.00601−1 = r

0.00601 = r

r × 12 = 0.07212, or approximately 7.21%

考点:bond valuation

解析:利用计算器:PV= -75,FV=100,PMT=0,N=4×12=48,求得:I/Y=0.601×12=7.21,故选项B正确。

能否这样计算?

75乘以(1+r/12)的48次方等于100。

嗨,爱思考的PZer你好:


解析中也有相应的步骤。解析中红框两个联系在一起,就是你的列式。
