问题如下:
A trader found a bond that is trading at different prices among markets as below:
Below is Yield to Maturity Par Rates for One- Two- and Three-Year Bonds:
Based on Exhibits 1 and 2, the exchange that reflects the arbitrage-free price of the bond is:
选项:
A.Eurex.
B.Frankfurt.
C.NYSE Euronext.
解释:
C is correct
考点:Introduction of Arbitrage Free Valuation
解析:
本题是计算出债券的Arbitrage-free price,即,用Spot rate对债券进行折现。
表格里面给定的是1,2,3年期的Par rates,因此需要通过Bootstrapping的方式,由前向后推导出Spot rate。已知1-year par rate等于1.25%,则1-year spot rate也等于1.25%
第二年spot rate计算:
求得S2=1.5019
同理,我们可以计算出第三年的Spot rate:S3=1.7049%
该债券的价值计算如下:
发现对于NYSE Euronext价格相差非常小,所以该交易所定价是合理的。
coupon为3%,为什么用1.5折现?
