问题如下图:老师,能否比较下NO.PZ2015122802000043,这两个题目的问题是一样的啊,为啥算法不一样呢?我已经被搞晕了。
选项:
A.
B.
C.
解释:
NO.PZ2015122802000045问题如下 analyst gathers the following information for a price-weighteinx compriseof securities ABF, anGHI:The prireturn of the inx is:A.–4.6%.B.–9.3%.C.–13.9%. is correct.The prireturn of the price-weighteinx is the percentage change in priof the inx: (68 –75)/75 = –9.33%.考点价格加权指数计算prireturn这道题原解析已经很清晰了,只要注意我们这里计算的是prireturn,所以不需要考虑期间收益。 计算时为什么不考虑vin?

NO.PZ2015122802000045 问题如下 analyst gathers the following information for a price-weighteinx compriseof securities ABF, anGHI:The prireturn of the inx is: A.–4.6%. B.–9.3%.

NO.PZ2015122802000045 为什么不能分别算r1 r2 r3取平均 不应该是a吗
NO.PZ2015122802000045 请问下为什么不是分别求期初以及期末时3只股票的算数平均, 然后计算价格汇报率? 而是3个价格加总来求?
