问题如下:
An analyst gathers the following information for an equal-weighted index comprised of assets Able, Baker, and Charlie:
The price return of the index is:
选项:
A. 1.7%.
B. 5.0%.
C. 11.4%.
解释:
B is correct.
The price return is the sum of the weighted returns of each security. The return of Able is 20 percent [(12 – 10)/10]; of Baker is –5 percent [(19 – 20)/20]; and of Charlie is 0 percent [(30 – 30)/30]. The price return index assigns a weight of 1/3 to each asset; therefore, the price return is 1/3 × [20% + (–5%) + 0%] = 5%.
考点:Methods of index construction
这道题让我们计算的是等权重构建方法下的指数的price return,所以我们首先要区分price return和total return,计算price return不需要包括期间的收益即股息。第二,这里是等权重的构建方法,等权重相当于每只股票买了相同的金额,那么我们就先计算每种股票的收益率再除以股票种类。
参照例题,假设每种股票买loo块钱的,算出来是这样(12x10+19*5+30*3.3)/300-1=4.7% 老师这样对么
