问题如下:

Aron wants to analyze the foreign-currency return for Portfolio Y. The domestic currency is EUR and the foreign currency is GBP. It is known that the domestic-currency return is 2%, and GBP appreciated 7% against the EUR.

The foreign-currency portfolio return is:

选项:

A.

-4.67%

B.

9.68%

C.

4.90%

解释:

A is correct.

考点:Currency Risk & Portfolio Return and Risk

RDC=(1+RFC)(1+RFX)1R_{DC}=(1+R_{FC})(1+R_{FX})-1

已知domestic-currency return is 2%, 即 RDC=2%R_{DC}=2\%。GBP appreciated 7% against the EUR,根据EUR/GBP(DC/FC)的外汇报价方式,GBP升值7%,即 RFX=7%R_{FX}=7\%。代入公式,可以求出 RFC=4.67%R_{FC}=-4.67\%

 GBP appreciated 7% against the EUR EUR/GBP, 老师这里我能说等价于 EUP depreciated 7% against the GBP 吗

嗨,努力学习的PZer你好:


是的,你可以这么说。GBP(英镑)相对于EUR(欧元)升值7%,等价于EUR(欧元)相对于GBP(英镑)贬值7%。换句话说,如果一种货币对另一种货币升值,那么另一种货币对第一种货币就会贬值,相应的百分比是相同的。

例如,如果最初的EUR/GBP汇率是0.90,然后GBP相对于EUR升值7%,新的汇率将是0.90 * (1 - 0.07) = 0.837。反过来说,EUR相对于GBP贬值7%,也会使汇率从0.90变为0.837。

----------------------------------------------
虽然现在很辛苦,但努力过的感觉真的很好,加油!

不对哦 我重新看了基础班P194 那道题, S0:EUR/GBP=0.9 GBP appreciated 7% against the EUR EUR/GBP, 应该是0.90 * (1 + 0.07) = 0.963 为S1, 如果说EUR相对GBP来说,考察对象应该是个EUR, 必须写成 GBP/EUR 格示,那EUR against GBP 应该是1/0.963 /(1/0.9)-1=-6.54%就是说EUR depreciated 5.54% against GBP吧

嗨,爱思考的PZer你好:


这里如果要讨论是否等价的话,默认是基于相同的报价方式,如果这里报价方式变化的话,算出来的升值贬值的幅度是不一样的。

就算太阳没有迎着我们而来,我们正在朝着它而去,加油!
