How Do You Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit ÷ Shareholders' Equity

Or for Zhejiang Cangnan Instrument Group:

22% = CN¥213m ÷ CN¥971m (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. Shareholders' equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.

What Does ROE Signify?

ROE measures a company's profitability against the profit it retains, and any outside investments. The 'return' is the amount earned after tax over the last twelve months. That means that the higher the ROE, the more profitable the company is. 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 Zhejiang Cangnan Instrument Group Have A Good Return On Equity?

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 you can see in the graphic below, Zhejiang Cangnan Instrument Group has a higher ROE than the average (9.3%) in the Electronic industry.

That's what I like to see. In my book, a high ROE almost always warrants a closer look. For example you might check if insiders are buying shares.

How Does Debt Impact 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 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.

Combining Zhejiang Cangnan Instrument Group's Debt And Its 22% Return On Equity

Zhejiang Cangnan Instrument Group has a debt to equity ratio of just 0.072, which is very low. Its ROE is very impressive, and given only modest debt, this suggests the business is high quality. 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.

The Key Takeaway

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