Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). By way of learning-by-doing, we’ll look at ROE to gain a better understanding of D-Link (India) Limited (NSE:DLINKINDIA).

Our data shows D-Link (India) has a return on equity of 13% for the last year. Another way to think of that is that for every ₹1 worth of equity in the company, it was able to earn ₹0.13.

### How Do You Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit ÷ Shareholders’ Equity

13% = ₹264m ÷ ₹2.1b (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 all earnings retained by the company, plus any capital paid in by shareholders. The easiest way to calculate shareholders’ equity is to subtract the company’s total liabilities from the total assets.

### What Does ROE 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 equal, investors should like a high ROE. That means ROE can be used to compare two businesses.

### Does D-Link (India) Have A Good Return On Equity?

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. As you can see in the graphic below, D-Link (India) has a higher ROE than the average (9.9%) in the Electronic industry.

That is a good sign. We think a high ROE, alone, is usually enough to justify further research into a company. One data point to check is if insiders have bought shares recently.

### 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 case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the debt used for growth will improve returns, but won’t affect the total equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

### Combining D-Link (India)’s Debt And Its 13% Return On Equity

Shareholders will be pleased to learn that D-Link (India) has not one iota of net debt! So although its ROE isn’t that impressive, we shouldn’t judge it harshly on that metric, because it didn’t use debt. After all, with cash on the balance sheet, a company has a lot more optionality in good times and bad.

### The Bottom Line On ROE

Return on equity is useful for comparing the quality of different businesses. A company that can achieve a high return on equity without debt could be considered a high quality business. If two companies have the same ROE, then I would generally prefer the one with less debt.

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. So I think it may be worth checking this free this detailed graph of past earnings, revenue and cash flow .
