Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). We'll use ROE to examine Eneva S.A. (BVMF:ENEV3), by way of a worked example.
Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. Simply put, it is used to assess the profitability of a company in relation to its equity capital.

The formula for ROE is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for Eneva is:
5.8% = R$944m ÷ R$16b (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 R$1 worth of equity, the company was able to earn R$0.06 in profit.
By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. You can see in the graphic below that Eneva has an ROE that is fairly close to the average for the Renewable Energy industry (5.8%).
That isn't amazing, but it is respectable. Although the ROE is similar to the industry, we should still perform further checks to see if the company's ROE is being boosted by high debt levels. If so, this increases its exposure to financial risk.
Most companies need money -- from somewhere -- to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
It's worth noting the high use of debt by Eneva, leading to its debt to equity ratio of 1.20. The combination of a rather low ROE and significant use of debt is not particularly appealing. Investors should think carefully about how a company might perform if it was unable to borrow so easily, because credit markets do change over time.
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. All else being equal, a higher ROE is better.
But when a business is high quality, the market often bids it up to a price that reflects this. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward. So I think it may be worth checking this free report on analyst forecasts for the company.
But note: Eneva may not be the best stock to buy. So take a peek at this free list of interesting companies with high ROE and low debt.
