weight怎么计算的

NO.PZ202208100100000501 问题如下 Baseon the information proviin Exhibit 1, the mestic currenvalue of as’s foreign investments most likely: A.creasebecause of changes in the mestic currenvalue of foreign asset holngs. B.increasebecause of changes in the mestic currenvalue of UK assets but creasebecause of changes in the mestic currenvalue of Germassets. C.increasebecause of changes in the mestic currenvalue of foreign asset holngs. SolutionC is correct. The mestic currenvalue of as’s portfolio of foreign assets most likely increasebecause of changes in the mestic currenvalue of foreign asset holngs. The mestic currenreturn of the portfolio of foreign assets is:R = w1(1 + RFC,G)(1 + RFX,G ）+ w2(1 + RFC,EUR )(1 + RFX,EUR ) – 1 = 0.659(86,000,000/83,400,000)(4.1025/3.8729) + 0.341(51,000,000/55,000,000)(3.5142/3.0359) = 0.659(1.0312)(1.0592) + 0.341(0.9273)(1.1575) = 0.659(1.0923) + 0.341(1.0734) = 0.0858The calculations show ththe mestic currenvalue of the portfolio of foreign assets increasebecause of changes (i.e., increases) in the mestic currenvalue of UK anGermequity investments. Note:w1 = 322,999,860/489,974,360 = 0.659，an2 = 166,974,500/489,974,360 = 0.341A is incorrect. The mestic currenvalue of the portfolio increase anthe mestic currenvalue of UK anGerminvestments increaseB is incorrect. The mestic currenvalue of the portfolio increasebecause of increases in the mestic currenvalue of UK anGerminvestments. It is the foreign currenvalue of Germequity investments thcline 中文解析在本题中本币为BRL，由上面的计算可知本币的收益R为0.0858，是大于0的，因此首先判断the mestic currenvalue是增加了的。然后根据计算过程可知外币英镑资产和外币欧元资产的收益率都是大于1的（分别是1.0923和1.0734），因此可以知道这两种资产都会使得本币资产增加。 老师，这道题为什么不能选B？
