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.
老师好，请教下， 对于A选项本身想多请教下，请问unaffected by stocks splits 的方法是哪几个啊？我确定的是市值为权重的话符合这个条件，请教下别的方法受stock split影响吗？
