这里是price-weighting index的内容吧,好像不太明白怎么变
NO.PZ2018062002000052 问题如下 Whipart of the formulis requireaustment after a stosplit when using the priweighting metho A.nominator. B.Numerator. 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. stosplit,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。
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
