Abstract
This paper demonstrates why EPS comparisons across companies are meaningless. An example is provided showing how a company with a higher ROE than another company may have a lower EPS simply from having a lower book value per share (and more shares outstanding) than the comparison company. While ROE comparisons across companies can be useful, cross-company EPS comparisons are meaningless due to the arbitrary number of shares outstanding across companies. The authors review the EPS discussion of 31 financial and intermediate accounting textbooks aimed at US students and find that six of these textbooks incorrectly assert or imply that cross-company EPS comparisons are meaningful. Over 50% of the textbooks reviewed provide no warning that cross-company EPS comparisons should be avoided.
