单项选择题
An analyst does research about security market indices and gathers the following information about market-capitalization-weighted index consisting of the shares of three companies:
| Company | Beginning Share Prices | Ending Share Prices | Dividends Per Share | Shares Outstanding |
| A | $26 | $21 | $1.60 | 300 |
| B | $51 | $46 | $2.10 | 300 |
| C | $11 | $13 | $3.10 | 400 |
A. -16.55%
B. -8.00%
C. 0.55%
答案
参考答案：B
解析：
初值：$26×300+$51×300+$11×400=$27500，终值：$21×300+$46×300+$13×400=$25300，指数价格回报率=(25300-27500)/27500=-8%。指数价格回报率只考虑价格变化，而总回报率还要考虑发放的股利。
