问题如下:
Given the information for the three stocks presented in the table, calculate the price-weighted index return over a 1-month period.
选项:
A.15.37%.
B.15.50%.
C.16%.
解释:
A is Correct.
(15+20+30)/3=21.67,
(20+30+25)/3=25,
25/21.67-1=15.37%
因为是price-weighted index, 可以假设每只股票都买一只
所以return就是:(75-65)/65,(期末价格-期初价格)/期初价格
