# Is Cochin Shipyard Limited's (NSE:COCHINSHIP) ROE Of 15% Impressive?

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 Cochin Shipyard Limited (NSE:COCHINSHIP).

Our data shows Cochin Shipyard has a return on equity of 15% for the last year. One way to conceptualize this, is that for each â‚¹1 of shareholders' equity it has, the company made â‚¹0.15 in profit.

### How Do I Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit Ã· Shareholders' Equity

Or for Cochin Shipyard:

15% = â‚¹4.9b Ã· â‚¹33b (Based on the trailing twelve months to June 2019.)

Most readers would understand what net profit is, but itâ€™s worth explaining the concept of shareholdersâ€™ equity. 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?

ROE measures a company's profitability against the profit it retains, and any outside investments. The 'return' is the yearly profit. The higher the ROE, the more profit the company is making. So, all else equal, investors should like a high ROE. That means ROE can be used to compare two businesses.

### Does Cochin Shipyard 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. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As is clear from the image below, Cochin Shipyard has a better ROE than the average (11%) in the Machinery industry.

That is a good sign. We think a high ROE, alone, is usually enough to justify further research into a company. For example, I often check if insiders have been buying shares .

### The Importance Of Debt To Return On Equity

Most companies need money -- from somewhere -- to grow their profits. That cash can come from retained earnings, issuing new shares (equity), or debt. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the use of debt will improve the returns, but will not change the equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

### Cochin Shipyard's Debt And Its 15% ROE

While Cochin Shipyard does have a tiny amount of debt, with debt to equity of just 0.037, we think the use of debt is very modest. I'm not impressed with its ROE, but the debt levels are not too high, indicating the business has decent prospects. Judicious use of debt to improve returns can certainly be a good thing, although it does elevate risk slightly and reduce future optionality.

### In Summary

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. In my book the highest quality companies have high return on equity, despite low debt. If two companies have the same ROE, then I would generally prefer the one with less debt.

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.
