单选题 An analyst does research about securitiesmarket indices. Which of the following statements is least accurate to make a price-weighted index biased?
A. A stock has a high price.
B. A stock splits frequently.
C. A stock has a large market capitalization.

【正确答案】 C
【答案解析】[解析] 价格权重指数主要的偏差源于价格高的股票在指数中的权重较大。市值权重指数主要的偏差源于市值越大的股票在指数中的权重越高。股票拆分会增加股票数量，但由于市值不变，故并不会影响市值权重指数。股票拆分虽然会向下调整指数的除数，以保持拆分前后股票指数一致，但随着股票价格的下降，会降低该股票在指数中的权重，从而会产生偏差。
