问题如下:
What is the approximate unhedged excess return to the United States–based credit manager for an international credit portfolio index equally weighted across the four portfolio choices, assuming no change to spread duration and no changes to the expected loss occur?
选项:
A.–0.257%
–0.850%
0.750%
解释:
A is correct. We solve for the excess spread by subtracting Expected Loss from
the respective OAS:
Recall that the United States–based investor must convert the euro return to US dollars using RDC = (1 + RFC) (1 + RFX) – 1, so the USD IG and USD HY positions comprising half the portfolio return an average 0.80%, while the EUR IG and EUR HY positions return –1.314% in US dollar terms (= ((1 + ((0.65% + 0.75%)/2)) × 0.98) – 1), so –0.257% = ((0.80% – 1.314%)/2).
请问0.98怎么来的?
