Answer:
the Clare account’s total (US dollar) return of 4.418%.
The weighted asset return is equal to 1.8%, calculated as follows:
(60%×5%)+[ 40%×(-3%)] = 1.8%
The domestic-currency return is equal to the sum of the weighted asset return, the weighted currency return, and the weighted cross-product of the asset return and the currency return. The latter two terms explain the effects of foreign-currency movements.
Therefore, the contribution of foreign currency equals 2.618% = 4.418% - 1.8% .
中文解析:
本题考察的是外汇投资中return的计算。
要求解的“the contribution of foreign currency”是包含了两部分的,一是RFX,二是交叉项RFC ×RFX。
因此,在总的return中减掉RFC 后,剩下的return就是由foreign currency贡献的return了。
另外一种计算方法:
the contribution of foreign currency = wiRFX
+wiRFCRFX
=0.6*0.02+0.4*0.035+0.6*0.05*0.02+0.4*0.035*(-0.03)=2.618%
用2.618%/4.418%=59%
