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. By way of learning-by-doing, we'll look at ROE to gain a better understanding of Tianjin Teda Co., Ltd. (SZSE:000652).

Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.

How Is ROE Calculated?

The formula for return on equity is:

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

So, based on the above formula, the ROE for Tianjin Teda is:

0.8% = CN¥51m ÷ CN¥6.6b (Based on the trailing twelve months to June 2024).

The 'return' is the amount earned after tax 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¥0.01 in profit.

Does Tianjin Teda Have A Good ROE?

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, Tianjin Teda has a lower ROE than the average (5.2%) in the Trade Distributors industry classification.

That's not what we like to see. However, a low ROE is not always bad. If the company's debt levels are moderate to low, then there's still a chance that returns can be improved via the use of financial leverage. A high debt company having a low ROE is a different story altogether and a risky investment in our books.

The Importance Of Debt To Return On Equity

Most companies need money -- from somewhere -- to grow their profits. That cash can come from issuing shares, retained earnings, or debt. 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. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

Tianjin Teda's Debt And Its 0.8% ROE

We think Tianjin Teda uses a significant amount of debt to maximize its returns, as it has a significantly higher debt to equity ratio of 3.60. The combination of a rather low ROE and high debt to equity is a negative, in our book.

Conclusion

Return on equity is useful for comparing the quality of different businesses. 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. 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.
