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 Nath Bio-Genes (India) Limited (NSE:NATHBIOGEN).
Over the last twelve months Nath Bio-Genes (India) has recorded a ROE of 7.0%. Another way to think of that is that for every ₹1 worth of equity in the company, it was able to earn ₹0.070.

How Do You Calculate Return On Equity?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Nath Bio-Genes (India):
7.0% = ₹349m ÷ ₹5.0b (Based on the trailing twelve months to December 2018.)
It's easy to understand the 'net profit' part of that equation, but 'shareholders' equity' requires further explanation. It is all the money paid into the company from shareholders, plus any earnings retained. 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 Mean?
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. A higher profit will lead to a higher ROE. So, as a general rule, a high ROE is a good thing. That means it can be interesting to compare the ROE of different companies.
Does Nath Bio-Genes (India) Have A Good Return On Equity?
Arguably the easiest way to assess company's ROE is to compare it with the average in 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 shown in the graphic below, Nath Bio-Genes (India) has a lower ROE than the average (9.0%) in the Food industry classification.
Unfortunately, that's sub-optimal. We'd prefer see an ROE above the industry average, but it might not matter if the company is undervalued. Still, shareholders might want to check if insiders have been selling.
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 case of the first and second options, the ROE will reflect this use of cash, for growth. 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.
Nath Bio-Genes (India)'s Debt And Its 7.0% ROE
While Nath Bio-Genes (India) does have a tiny amount of debt, with debt to equity of just 0.097, we think the use of debt is very modest. Its ROE is certainly on the low side, and since it already uses debt, we're not too excited about the company. Careful use of debt to boost returns is often very good for shareholders. However, it could reduce the company's ability to take advantage of future opportunities.
But It's Just One Metric
Return on equity is one way we can compare the business quality of different companies. 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. 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. So I think it may be worth checking this free this detailed graph of past earnings, revenue and cash flow .
