How Do I Calculate ROE?

The formula for ROE is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

Or for Thelloy Development Group:

29% = HK$40m ÷ HK$137m (Based on the trailing twelve months to September 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 looks at the amount a company earns relative to the money it has kept within the business. The 'return' is the amount earned after tax over the last twelve months. The higher the ROE, the more profit the company is making. So, all else being equal, a high ROE is better than a low one. That means it can be interesting to compare the ROE of different companies.

Does Thelloy Development Group Have A Good ROE?

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 is clear from the image below, Thelloy Development Group has a better ROE than the average (11%) in the Construction 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.

How Does Debt Impact ROE?

Most companies need money -- from somewhere -- 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 use of debt will improve the returns, but will not change the equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Combining Thelloy Development Group's Debt And Its 29% Return On Equity

Thelloy Development Group is free of net debt, which is a positive for shareholders. Its high ROE indicates the business is high quality, but the fact that this was achieved without leverage is veritably impressive. After all, when a company has a strong balance sheet, it can often find ways to invest in growth, even if it takes some time.

The Key Takeaway

Return on equity is one way we can compare the business quality of different companies. 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.

Having said that, while ROE is a useful indicator of business quality, you'll have to look at a whole range of factors to determine the right price to buy a stock. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
