单选题 Which of the following statements about indexes is TRUE? A. A price-weighted index assumes an equal number of shares (one of each stock) represented in the index. B. An unweighted index assumes a proportionate market value investment in each company in the index. C. A value weighted index assumes an investor makes and maintains an equal dollar investment in each stock in their portfolio.

【正确答案】 A

【答案解析】The descriptions of value weighted and unweighted indexes are switched. The denominator of a price-weighted index must be adjusted to reflect stock splits and changes in the sample over time. A market value-weighted series assumes you make a proportionate market value investment in each company in the index.
