The bond in Exhibit 2 with the best relative value is most likely:选项:
A.Bond D. B.Bond E. C.Bond F.解释:
SolutionA is correct. Bond D has the best relative value; its expected excess return (EXR) has the smallest loss given the expectation that credit spreads are going to widen by 25 bps (the change in the Z-spread). The expected excess return calculation is as follows:EXR = (s × t) – (∆s × SD) – (t × p × L)where
s = Z-spread
t = Holding period
SD = Spread duration
p = Probability of default
L = Loss severity
Calculations are as follows:
B is incorrect because Bond D has the best expected excess return.
C is incorrect because Bond D has the best expected excess return.
EXR = (s × t) – (∆s × SD) – (t × p × L),关于这个, 不同的题考了好几遍了,有些是用oas, 有些用zpread, 请问这个公式的的Spread是不是本来就可以自定义?yield spread,g-spread, asw等理论上都可以用?
