问题如下:
4. Based on the information in Exhibits 3 and 4, the bond price in euros at Node 1–2 in Exhibit 4 is closest to:
选项:
A.105.2917.
B.104.8640.
C.102.7917.
解释:
C is correct.
The value of a bond at a particular node, in this case Node 1–2, can be derived by determining the present value of the coupon payment and expected future bond values to the right of that node on the tree. In this case, those two nodes are the middle node in Year 2, equal to 101.5168, and the lower node in Year 2, equal to 102.1350. The coupon payment is 2.5. The bond value at Node 1–2 is calculated as follows:
Value = 0.5 × [ (101.5186/1.014925 + 102.1350/1.014925) ] + 2.5/1.014925 = 102.7917.
这个利率折现为什么不是一个是0.25,一个是0.5,怎么两个都是0.5的概率折现,都第三个分叉了。
