A.–0.257% B.–0.850% C.0.750% A is correct. We solve for the excess sprebysubtracting ExpecteLoss fromthe respective OAS:Recall ththe UniteStates–baseinvestor mustconvert the euro return to US llars using R =(1 + RF(1 + RFX)– 1, so the USIG anUSHY positions comprising half the portfolio return average0.80%, while the EUR IG anEUR HY positionsreturn –1.314% in US llterms (= ((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？
