问题如下：
Which part of the formular is required an adjustment after a stock split when using the price weighting method？
选项：
A. Denominator.
B. Numerator.
C. Both numerator and denominator.
解释：
Denominator must be adjusted after a stock split when using the price weighting method, in order to ensure index value immediately after the split is the same as the index value immediately prior to the split.
stock split，比如一直股票从100一股，变成50两股，那分子不是也从100降到50，分子分母不是同时改变了嘛。

C.Both numerator annominator. is correct.nominator must austeafter a stosplit when using the priweighting metho in orr to ensure inx value immeately after the split is the same the inx value immeately prior to the split.考点priweighting metho干问当股票分拆，价格加权指数公式的哪一部分需要进行调整。这里是price-weighting inx的内容，因为拆股所导致股价下降不是真正的股价下跌，所以我们要对指数的权重即分母进行调整。 看了解析还是有疑问，明白拆股只是从100变到50，实质并没有发生变化。分母需要重新计算，但是在代入公式时，分子的数值不也是发生了变化？
老师好，看了这么多的解答还是有点不太明白，能否举个具体的例子一下呢？谢谢！
老师 这道题是在讲义和视频哪个位置？
Numerator. Both numerator annominator. nominator must austeafter a stosplit when using the priweighting metho in orr to ensure inx value immeately after the split is the same the inx value immeately prior to the split.老师，不好意思，看了您对其他同学的回答，还是不太理解分子为什么没有变化，因为在计算平均价格的时候，分子中发生拆股的股票价格也是变化了呀
