One of the best investments we can make is in our own knowledge and skill set. With that in mind, this article will work through how we can use Return On Equity (ROE) to better understand a business. To keep the lesson grounded in practicality, we'll use ROE to better understand MECOM Power and Construction Limited (HKG:1183).
Our data shows MECOM Power and Construction has a return on equity of 12% for the last year. That means that for every HK$1 worth of shareholders' equity, it generated HK$0.12 in profit.
How Do You Calculate ROE?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for MECOM Power and Construction:
12% = MO$55m ÷ MO$451m (Based on the trailing twelve months to December 2018.)
Most know that net profit is the total earnings after all expenses, but the concept of shareholders' equity is a little more complicated. It is all earnings retained by the company, plus any capital paid in by shareholders. Shareholders' equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.
What Does Return On Equity Signify?
ROE measures a company's profitability against the profit it retains, and any outside investments. The 'return' is the yearly profit. The higher the ROE, the more profit the company is making. So, all else being equal, a high ROE is better than a low one. Clearly, then, one can use ROE to compare different companies.
Does MECOM Power and Construction Have A Good ROE?
One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. If you look at the image below, you can see MECOM Power and Construction has a similar ROE to the average in the Construction industry classification (11%).
That isn't amazing, but it is respectable. ROE tells us about the quality of the business, but it does not give us much of an idea if the share price is cheap. I will like MECOM Power and Construction better if I see some big insider buys. While we wait, check out this free list of growing companies with considerable, recent, insider buying.
How Does Debt Impact Return On Equity?
Companies usually need to invest money to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. That will make the ROE look better than if no debt was used.
MECOM Power and Construction's Debt And Its 12% ROE
One positive for shareholders is that MECOM Power and Construction does not have any net debt! Its solid ROE indicates a good business, especially when you consider it is not using leverage. At the end of the day, when a company has zero debt, it is in a better position to take future growth opportunities.
The Key Takeaway
Return on equity is one way we can compare the business quality of different companies. A company that can achieve a high return on equity without debt could be considered a high quality business. If two companies have around the same level of debt to equity, and one has a higher ROE, I'd generally prefer the one with higher ROE.
Having said that, while ROE is a useful indicator of business quality, you'll have to look at a whole range of factors to determine the right price to buy a stock. The rate at which profits are likely to grow, relative to the expectations of profit growth reflected in the current price, must be considered, too.
