While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. We'll use ROE to examine M-Grass Ecology And Environment (Group) Co., Ltd. (SZSE:300355), by way of a worked example.

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors' money. Put another way, it reveals the company's success at turning shareholder investments into profits.

How Do You Calculate Return On Equity?

The formula for ROE is:

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

So, based on the above formula, the ROE for M-Grass Ecology And Environment (Group) is:

3.2% = CN¥188m ÷ CN¥5.9b (Based on the trailing twelve months to March 2024).

The 'return' is the profit over the last twelve months. Another way to think of that is that for every CN¥1 worth of equity, the company was able to earn CN¥0.03 in profit.

Does M-Grass Ecology And Environment (Group) 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 is clear from the image below, M-Grass Ecology And Environment (Group) has a lower ROE than the average (5.2%) in the Commercial Services industry.

That's not what we like to see. That being said, a low ROE is not always a bad thing, especially if the company has low leverage as this still leaves room for improvement if the company were to take on more debt. When a company has low ROE but high debt levels, we would be cautious as the risk involved is too high. Our risks dashboard should have the 3 risks we have identified for M-Grass Ecology And Environment (Group).

Why You Should Consider Debt When Looking At 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 first and second cases, the ROE will reflect this use of cash for investment in the business. 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 M-Grass Ecology And Environment (Group)'s Debt And Its 3.2% Return On Equity

It's worth noting the high use of debt by M-Grass Ecology And Environment (Group), leading to its debt to equity ratio of 1.05. The combination of a rather low ROE and significant use of debt is not particularly appealing. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.

Summary

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. A company that can achieve a high return on equity without debt could be considered a high quality business. All else being equal, a higher ROE is better.

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. 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.
