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 Public Joint Stock Company Aeroflot - Russian Airlines (MCX:AFLT).
Our data shows Aeroflot - Russian Airlines has a return on equity of 0.8% for the last year. That means that for every RUB1 worth of shareholders' equity, it generated RUB0.0084 in profit.
How Do I Calculate ROE?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Aeroflot - Russian Airlines:
0.8% = RUруб1.3b ÷ RUруб45b (Based on the trailing twelve months to March 2019.)
Most readers would understand what net profit is, but it’s worth explaining the concept of shareholders’ equity. It is all the money paid into the company from shareholders, plus any earnings retained. The easiest way to calculate shareholders' equity is to subtract the company's total liabilities from the total assets.
What Does Return On Equity Mean?
ROE looks at the amount a company earns relative to the money it has kept within the business. The 'return' is the profit over the last twelve months. The higher the ROE, the more profit the company is making. So, as a general rule, a high ROE is a good thing. That means ROE can be used to compare two businesses.
Does Aeroflot - Russian Airlines Have A Good Return On Equity?
By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As is clear from the image below, Aeroflot - Russian Airlines has a lower ROE than the average (19%) in the Airlines industry.
That's not what we like to see. It is better when the ROE is above industry average, but a low one doesn't necessarily mean the business is overpriced. Nonetheless, it could be useful to double-check if insiders have sold shares recently.
How Does Debt Impact ROE?
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. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.
Combining Aeroflot - Russian Airlines's Debt And Its 0.8% Return On Equity
Aeroflot - Russian Airlines does use a significant amount of debt to increase returns. It has a debt to equity ratio of 2.13. Its ROE is quite low, even with the use of significant debt; that's not a good result, in my opinion. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.
The Key Takeaway
Return on equity is useful for comparing the quality of different businesses. In my book the highest quality companies have high return on equity, despite low debt. 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.
But when a business is high quality, the market often bids it up to a price that reflects this. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
