NO.PZ201601050100000101 问题如下 1. Analyze the movement of the USagainst the foreign currenfor Portfolio Justify your choice. Justification The 19.5% mestic-currenreturn for Portfolio A is higher ththe 15% foreign-currenportfolio return in GBP; therefore, the USnecessarily preciaterelative to the GBP. The mestic-currenreturn on a foreign portfolio will refleboth the foreign-currenreturn on the portfolio anthe percentage movements in the spot exchange rate between the mestic anforeign currency. The mestic-currenreturn is multiplicative with respeto these two factors: R = (1 + RFC)(1 + RFX) – 1 where R is the mestic-currenreturn (in percent), RFC is the foreign-currenreturn of the asset (portfolio), anRFX is the percentage change of the foreign currenagainst the mestic currency. (Note thin the RFX expression the mestic curren — the USin this case — is the pricurrency.) Solving for RFX: (1 + 15%)(1 + RFX) – 1 = 19.50%; RFX = 3.91% Thus, the USpreciaterelative to the GBP. This, the Gappreciateagainst the USbecause RFX is quotein terms of USGBP, with the USthe pricurrenanGthe base currency, anin this example RFX is a positive number (3.91%).中文解析本小题考察的是外汇投资中return的计算公式R = (1 + RFC )(1 + RFX ) – 1根据题干信息可知，R=19.5%,Rfc=15%，根据公式R = (1 + RFC)(1 + RFX) – 1 得到Rfx是大于0的，具体数值是3.91%，其中Rfx的汇率表达形式是本币/外币即USGBP，因此Rfx大于0，意味着GBP升值，对应的就是US值。 这道题一定要算出具体数值吗？我的回答如下没有列出公式，请问是否可以》USrelative to foreign-currenis preciateThe return of portfolio A is containe2 returns, return of foreign-currenportfolio anreturn of foreign currenexchange rate. Because the return of portfolio A is 19.5%, whiis higher ththe return of foreign-currenportfolio. Thus, the return of foreign currenexchange rate is positive, whimeans the foreign curren(GBP) appreciates anthe mestic curren(US preciates.

Portfolio A consists of British poun(GBP) nominatebon anPortfolio B hol euro (EUR) nominatebon\"，得出了/FC是USGor EUR，请问对吗？又根据题目USagainst GBP得到题目的格式是GBP/US请问against前面是base currency，against后是pricing currency，格式是pricing currency/base currency这个结论通用吗？
