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. By way of learning-by-doing, we'll look at ROE to gain a better understanding of Lumax Industries Limited (NSE:LUMAXIND).
Over the last twelve months Lumax Industries has recorded a ROE of 23%. One way to conceptualize this, is that for each ₹1 of shareholders' equity it has, the company made ₹0.23 in profit.
How Do I Calculate Return On Equity?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Lumax Industries:
23% = ₹1.0b ÷ ₹4.3b (Based on the trailing twelve months to June 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. 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 measures a company's profitability against the profit it retains, and any outside investments. The 'return' is the yearly profit. That means that the higher the ROE, the more profitable the company is. So, all else being equal, a high ROE is better than a low one. That means ROE can be used to compare two businesses.
Does Lumax Industries 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. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. Pleasingly, Lumax Industries has a superior ROE than the average (12%) company in the Auto Components industry.
That's clearly a positive. We think a high ROE, alone, is usually enough to justify further research into a company. For example you might check if insiders are buying shares.
The Importance Of Debt To 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 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.
Lumax Industries's Debt And Its 23% ROE
Although Lumax Industries does use debt, its debt to equity ratio of 0.32 is still low. The fact that it achieved a fairly good ROE with only modest debt suggests the business might be worth putting on your watchlist. Judicious use of debt to improve returns can certainly be a good thing, although it does elevate risk slightly and reduce future optionality.
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. All else being equal, a higher ROE is better.
But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward. So I think it may be worth checking this free report on analyst forecasts for the company.
