※ 引述《yesican (yeah)》之銘言: : Last year the price per share of Stock X increased by k percent and : the earnings per share of Stock X increased by m percent, where k is : greater than m. By what percent did the ratio of price per share to : earnings per share increase, in terms of k and m ? : 題目看不太懂 : 答案是 [(100(k-m))/(100+m)] % : what does the question mean? PE ratio=price/eps(每股價格/每股盈餘) 假設原本的PE ratio為P/E, 所以新的PE ratio=[(100+K)/(100+M)]*(P/E) 它是問你PE增加率 所以增加率為[新的PE ratio-舊的PE ratio]/舊的PE ratio =[(100+K)/(100+M)]-1 =(K-M)/(100+M) 轉換成%就是答案 -- No doubt, just keep walking -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 118.168.80.163 ※ 編輯: flac 來自: 118.168.80.163 (07/24 14:00)
