One of the best investments we can make is in our own knowledge and skill set. With that in mind, this article will work through how we can use Return On Equity (ROE) to better understand a business. To keep the lesson grounded in practicality, we'll use ROE to better understand TCL Technology Group Corporation (SZSE:000100).

Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. Simply put, it is used to assess the profitability of a company in relation to its equity capital.

How Do You Calculate Return On Equity?

ROE can be calculated by using the formula:

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

So, based on the above formula, the ROE for TCL Technology Group is:

6.4% = CN¥7.6b ÷ CN¥119b (Based on the trailing twelve months to June 2022).

The 'return' refers to a company's earnings over the last year. So, this means that for every CN¥1 of its shareholder's investments, the company generates a profit of CN¥0.06.

Does TCL Technology 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. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As shown in the graphic below, TCL Technology Group has a lower ROE than the average (10%) in the Consumer Durables industry classification.

That certainly isn't ideal. Although, we think that a lower ROE could still mean that a company has the opportunity to better its returns with the use of leverage, provided its existing debt levels are low. A company with high debt levels and low ROE is a combination we like to avoid given the risk involved. Our risks dashboard should have the 4 risks we have identified for TCL Technology Group.

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 first and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

TCL Technology Group's Debt And Its 6.4% ROE

It's worth noting the high use of debt by TCL Technology Group, leading to its debt to equity ratio of 1.15. Its ROE is quite low, even with the use of significant debt; that's not a good result, in our opinion. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.

Conclusion

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. 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. 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 you might want to take a peek at this data-rich interactive graph of forecasts for the company.
