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 Tianjin Teda Co., Ltd. (SZSE:000652), 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 To 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 Tianjin Teda is:

0.6% = CN¥42m ÷ CN¥6.6b (Based on the trailing twelve months to September 2024).

The 'return' is the amount earned after tax over the last twelve months. That means that for every CN¥1 worth of shareholders' equity, the company generated CN¥0.01 in profit.

Does Tianjin Teda 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. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As is clear from the image below, Tianjin Teda has a lower ROE than the average (6.5%) in the Trade Distributors industry.

Unfortunately, that's sub-optimal. 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.

Why You Should Consider Debt When Looking At ROE

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 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.

Tianjin Teda's Debt And Its 0.6% ROE

It appears that Tianjin Teda makes extensive use of debt to improve its returns, because it has an alarmingly high debt to equity ratio of 3.63. We consider it to be a negative sign when a company has a rather low ROE despite a rather high debt to equity.

Conclusion

Return on equity is one way we can compare its business quality of different companies. Companies that can achieve high returns on equity without too much debt are generally of good quality. If two companies have the same ROE, then I would generally prefer the one with less debt.

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.
