请问如何按计算器?

NO.PZ2016031001000076

问题如下:

A 5-year, 5% semiannual coupon payment corporate bond is priced at 104.967 per 100 of par value. The bond’s yield-to-maturity, quoted on a semiannual bond basis, is 3.897%. An analyst has been asked to convert to a monthly periodicity. Under this conversion, the yield-to-maturity is closest to:

选项:

A.

3.87%.

B.

4.95%.

C.

7.67%.

解释:

A is correct.

The yield-to-maturity, stated for a periodicity of 12 (monthly periodicity), is 3.87%.The formula to convert an annual percentage rate (annual yield-to-maturity) from one periodicity to another is as follows:

(1+APRmm)m=(1+APRnn)n{(1+\frac{APRm}m)}^m={(1+\frac{APRn}n)}^n

(1+0.038972)2=(1+APR1212)12{(1+\frac{0.03897}2)}^2={(1+\frac{APR12}{12})}^{12}

(1.01949)2=(1+APR1212)12{(1.01949)}^2={(1+\frac{APR12}{12})}^{12}

1.03935=(1+APR1212)121.03935={(1+\frac{APR12}{12})}^{12}

(1.03935)1/12=[(1+APR1212)12]1/12{(1.03935)}^{1/12}={\lbrack{(1+\frac{APR12}{12})}^{12}\rbrack}^{1/12}

1.00322=(1+APR1212)1.00322={(1+\frac{APR12}{12})}

1.003221=(APR1212)1.00322-1={(\frac{APR12}{12})}

APR12 = 0.00322 × 12 = 0.03865, or approximately 3.87%.

考点:APR的转换

解析:这里考查的是不同计息频率的收益率之间的转换。一年计息两次的年化收益率,即APR2 ,转换到一年计息12次的APR12 ,可以同时转换到一年计息一次(相当于一个过渡)。即(1+APR2 /2)2 =1+EAR=(1+APR12 /12)12 ,得到APR12 为3.87%。

这里求出或者看出一年计息两次的变化收益率是3.897%之后怎么按计算器求出最终答案?题目是要求按出计息12次的年化收益率吗?

嗨,从没放弃的小努力你好:


先按出左边:(1+0.03897/2)^2=1.0393,然后保留到STO---1


然后按1/12,然后保留到STO---2


依次按RCL---1---yx---RCL----2(这样相当于把存在1和2键的数字开了十二次方)


最后(1.00322-1)*12=0.0387

我用计算器这么按的 N=5*12=60 PV= -104.967  PMT= 100*5%/12=0.4167 FV=100 算出来 IY=0.3254这个应该是月化,我再乘以 12 得到对应的年化是 3.9,为什么这样是不对的呢?
