PV=100×(1-180/360×4.25%)

NO.PZ2016031001000084

问题如下:

The bond equivalent yield of a 180-day banker’s acceptance quoted at a discount rate of 4.25% for a 360-day year is closest to:

选项:

A.

4.31%.

B.

4.34%.

C.

4.40%.

解释:

C is correct.

The bond equivalent yield is closest to 4.40%. The present value of the banker’s acceptance is calculated as:

PV=FV×(1DaysYear×DR)PV=FV\times{(1-\frac{Days}{Year}\times DR)}

PV=100×(1DaysYear×DR)PV=100\times{(1-\frac{Days}{Year}\times DR)}

PV=100×(1180360×0.0425)PV=100\times{(1-\frac{180}{360}\times0.0425)}

PV = 100 × (1 – 0.02125)

PV = 100 × 0.97875

PV = 97.875

The bond equivalent yield (AOR) is calculated as:

AOR=(YearDays)×(FVPVPV)AOR={(\frac{Year}{Days})}\times{(\frac{FV-PV}{PV})}

AOR=(365180)×(100PVPV)AOR={(\frac{365}{180})}\times{(\frac{100-PV}{PV})}

AOR=(365180)×(10097.87597.875)AOR={(\frac{365}{180})}\times{(\frac{100-97.875}{97.875})}

AOR = 2.02778 × 0.02171

AOR = 0.04402, or approximately 4.40%

Note that the PV is calculated using an assumed 360-day year and the AOR (bond equivalent yield) is calculated using a 365-day year.

考点:Yield Measures

解析:考查的是discount yield和 add-on yield之间的转换。1.题目给出了discount rate=4.25%,可以算出PV=100×(1-180/360×4.25%)=97.875。2.然后通过计算出来的PV再计算BEY,BEY就是365天形式的add-on-yield,BEY=365/180×(100-97.875)/97.875=4.40%,故选项C正确。

为什么不是100/(1+180/360×4.25%)

嗨,爱思考的PZer你好:


怎么区分折现和折价呢

Hello ,亲爱的同学~

可以有两个方法来辨别。


第一个方法是根据知识点记忆住术语。

这里是个特定的知识点,讲的是浮息债券的定价。

浮息债券定价里,有一个术语,就是discount rate。

所以看到discount rate这个词,就要想到折价率。

也就是上面的priced at dsicount。


第二个方法是看题目里的信息点。

结合本题: (半年期)quoted at a discount rate of 4.25%。

quoted是报价的意思。

以4.25%的折价率来报价。

因此债券价格是:100 × (1 – 4.25%/2)。

这就是浮息债券的特有的报价方法:它不会说债券价格是 97.875,它说债券价格是以discount rate =4.25%报价。

同学需要知道两者的转换。

嗨,从没放弃的小努力你好:


为什么不是100/(1+180/360×4.25%)

Hello,亲爱的同学~

这里的discount yield不能理解为“折现率”。要理解为“折价率”。

折现率,涉及到除法。但折价率,就涉及到乘法了。

这个折价率,是相对面值的折价。

一个半年期的债券,年化折价率是4.25%。

市场价格就等于:100 × (1 – 4.25%/2)。

就算太阳没有迎着我们而来,我们正在朝着它而去,加油!
