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 Reliance Industrial Infrastructure Limited (NSE:RIIL).
Reliance Industrial Infrastructure has a ROE of 2.5%, based on the last twelve months. Another way to think of that is that for every ₹1 worth of equity in the company, it was able to earn ₹0.025.
How Do I Calculate ROE?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Reliance Industrial Infrastructure:
2.5% = ₹93m ÷ ₹3.7b (Based on the trailing twelve months to March 2019.)
It's easy to understand the 'net profit' part of that equation, but 'shareholders' equity' requires further explanation. It is the capital paid in by shareholders, plus any retained earnings. Shareholders' equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.
What Does ROE Signify?
Return on Equity measures a company's profitability against the profit it has kept for the business (plus any capital injections). The 'return' is the amount earned after tax over the last twelve months. The higher the ROE, the more profit the company is making. So, all else equal, investors should like a high ROE. That means it can be interesting to compare the ROE of different companies.
Does Reliance Industrial Infrastructure Have A Good ROE?
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 shown in the graphic below, Reliance Industrial Infrastructure has a lower ROE than the average (13%) in the Oil and Gas industry classification.
Unfortunately, that's sub-optimal. It is better when the ROE is above industry average, but a low one doesn't necessarily mean the business is overpriced. Nonetheless, it might be wise to check if insiders have been selling.
How Does Debt Impact Return On Equity?
Companies usually need to invest money to grow their profits. That cash can come from issuing shares, retained earnings, or debt. In the first and second cases, the ROE will reflect this use of cash for investment in the business. 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.
Reliance Industrial Infrastructure's Debt And Its 2.5% ROE
One positive for shareholders is that Reliance Industrial Infrastructure does not have any net debt! So while I find its ROE to be rather low, at least it didn't use debt. At the end of the day, when a company has zero debt, it is in a better position to take future growth opportunities.
But It's Just One Metric
Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. Companies that can achieve high returns on equity without too much debt are generally of good quality. 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. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
