If you give some management teams a couple of boards, some glue, and a ball of string, they can build a profitable growing business, while other teams can’t make a profit with several billion dollars worth of assets.
Return on Equity (ROE) is one measure of how efficiently a company uses its assets to produce earnings. You calculate ROE by dividing Net Income by Book Value. A healthy company may produce an ROE in the 13% to 15% range. Like all metrics, compare companies in the same industry to get a better picture.
While ROE is a useful measure, it does have some flaws that can give you a false picture, so never rely on it alone. For example, if a company carries a large debt and raises funds through borrowing rather than issuing stock it will reduce its book value. A lower book value means you’re dividing by a smaller number so the ROE is artificially higher. There are other situations such as taking write-downs, stock buy backs, or any other accounting slight of hand that reduces book value, which will produce a higher ROE without improving profits.
It may also be more meaningful to look at the ROE over a period of the past five years, rather than one year to average out any abnormal numbers.
Given that you must look at the total picture, ROE is a useful tool in identifying companies with a competitive advantage. All other things roughly equal, the company that can consistently squeeze out more profits with their assets, will be a better investment in the long run.
