问题如下：
The initial benchmark used for the US large-cap allocation:
选项：
A.is unaffected by stocks splits.
B.is essentially a liquidity-weighted index.
C.holds the same number of shares in each component stock.
解释：
C is correct. The initial benchmark used for the US large-cap allocation is a price-weighted index. In a price-weighted index, the weight of each stock is its price per share divided by the sum of all the share prices in the index. As a result, a price-weighted index can be interpreted as a portfolio composed of one share of each constituent security.
我记得老师曾经说过，拆股只是数字游戏，并不导致指数的变化，分子的股价下降了，用于计算指数的除数也就是分母也会相应调整，为什么还会对最终index产生影响呢？
