问题如下：
Allen, the director of the equity research department in a small securities firm, asks John, a junior analyst to use the relative value method to find investment opportunities among 4 comparable companies operating in the automobile industry. The information about the companies he collected are shown below:
According to the information above, which of the following is correct?
选项：
A.Company A is relatively undervalued, as it has the lowest P/E ratio.
B.Because of the negative earnings, E/P ratio, the earnings yield is a more appropriate metric than P/E ratio to rank the relative value among these companies. As company D has the lowest E/P ratio, it is the cheapest stock among 4 companies.
C.Ranking the companies by E/P ratio, company A is the cheapest stock among 4 companies, as it has the highest E/P ratio.
解释：
C is correct.
考点：考察E/P的使用情景；考察用E/P比较相对价值
解析：注意到C，和D公司有负的Earnings，则不能使用P/E ratio进行比较。由所给数据可以使用E/P ratio。将E/P ratio由大到小的顺序进行排序，E/P ratio越大代表，相对于其股价，公司的Earnings越高，则代表股票相对越便宜。
他说是most expensive，应该说是overvalued吧？ most expensive 是说earning一样大时候比较价格吧，这样表述不严谨吧？
