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). By way of learning-by-doing, we’ll look at ROE to gain a better understanding of TransAlta Corporation (TSE:TA).
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 other words, it is a profitability ratio which measures the rate of return on the capital provided by the company’s shareholders.
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders’ Equity
So, based on the above formula, the ROE for TransAlta is:
35% = CA$669m ÷ CA$1.9b (Based on the trailing twelve months to June 2024).
The ‘return’ is the amount earned after tax over the last twelve months. One way to conceptualize this is that for each CA$1 of shareholders’ capital it has, the company made CA$0.35 in profit.
By comparing a company’s ROE with its industry average, we can get a quick measure of how good it is. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. Pleasingly, TransAlta has a superior ROE than the average (7.7%) in the Renewable Energy industry.
That’s clearly a positive. However, bear in mind that a high ROE doesn’t necessarily indicate efficient profit generation. Especially when a firm uses high levels of debt to finance its debt which may boost its ROE but the high leverage puts the company at risk. Our risks dashboardshould have the 5 risks we have identified for TransAlta.
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 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.
It’s worth noting the high use of debt by TransAlta, leading to its debt to equity ratio of 2.12. Its ROE is pretty impressive but, it would have probably been lower without the use of debt. 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. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
