选项AB都会PE变大吧，这道题是不是有错啊？
问题如下图：
选项：
A. 
B. 
C. 
解释：
NO.PZ2018091701000022 问题如下 Whiof the following statement is most likely to support the P/E ten to rise: A.A crease in the expectefuture reearnings growth. B.A fall in the equity risk premium. C.increase in uncertainty about future inflation B is correct.考点equity risk premium的计算解析这里有个大原则，就是分母变小或者分子变大，都会增加P/E。只有B是分母变小，所以P/E会变大。 老师， “A crease in the expectefuture reearnings growth.”如何理解？ 它不是分子么？

NO.PZ2018091701000022 A crease in the expectefuture reearnings growth. 可以理解为计算P的CF减少，所以PE降低
老师，这道题目算P的话，不能用GGM模型吗？一定是CF之和除以R吗？
这道题基础班有讲过我知道，但我还是想不通，为什么earnings growth增加影响的是分子不是分母呢？分母不就是earning吗？
