就是股票的加个涨了k%,股利增了m%,问股价/股利的比例增加了多少

[p(1+k%)]/[e(1+m%)]-p/e

D.     [100(km)] / (100 + m) %

E.      [100(km)] / (100 + k + m) %

the ratio of price per share 1+k%)

the ratio of earnings per share 1+m%)

((1+k%)-(1+m%))/(1+m%)=[100(km)] / (100 + m) %

earnings per share :每股盈利

顶一下,谁能帮普及一下这道题的背景知识么?

每股股价和每股盈利的关系?

题目基本作对了,但基本是不知道怎么做对的。谢谢NN
