问题如下:
Exhibit below shows information about selected Fixed-Rate Bonds of Alpha Corporation
Note: All bonds in Exhibit 2 have remaining maturities of exactly three years
Smith explains that the divergence in economic data leads him to believe that volatility in interest rates will increase. If Smith’s interest rate volatility forecast turns out to be true, which bond in Exhibit 2 is likely to experience the greatest price increase?
选项:
A.Bond 2
B.Bond 3
C.Bond 4
解释:
B is correct.
考点:考察利率波动率对含权债券的影响
解析:
利率波动性的增加将导致债券3 (Putable bond)和债券4 (Callable bond)中的Embedded option的价值增加。
对于债券3 ( Putable bond ) , 由于期权属于投资者 , 因此Putable bond的价值将会上涨 。 对于债券4 ( Callable bond ) , 由于期权属于发行人 , 期权价值的上升 , 将会使得callable bond的价值下跌 。 债券2 ( Convertible bond ) , Embedded option当前的状态是虚值期权 , 可转债的表现为Straight bond , 因此受到利率波动率变化影响微乎其微 。
老师,这道题我有如下疑问:
1)利率波动率大,不是导致P下降,即然价格下降,putable 不会导致价格下跌更多,那怎么是价格变动最大呢?
2)利率和收益率,您能帮我区分下么?
