问题如下:
An analyst gathers the following data for a price-weighted index:
The price return of the index over the period is:
选项:
A.4.2%.
B.7.1%.
C.21.4%.
解释:
A is correct.
The sum of prices at the beginning of the period is 96; the sum at the end of the period is 100. Regardless of the divisor, the price return is 100/96 – 1 = 0.042 or 4.2 percent.
这里的价格96和100都应该除以3吧,课程里面都是平均价,虽然结果一样的
