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). To keep the lesson grounded in practicality, we'll use ROE to better understand CSX Corporation (NASDAQ:CSX).

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 To Calculate Return On Equity?

Return on equity 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 CSX is:

28% = US$3.7b ÷ US$13b (Based on the trailing twelve months to September 2024).

The 'return' is the income the business earned over the last year. One way to conceptualize this is that for each $1 of shareholders' capital it has, the company made $0.28 in profit.

Does CSX Have A Good ROE?

By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. Pleasingly, CSX has a superior ROE than the average (14%) in the Transportation industry.

That's what we like to see. However, bear in mind that a high ROE doesn't necessarily indicate efficient profit generation. Aside from changes in net income, a high ROE can also be the outcome of high debt relative to equity, which indicates risk.

How Does Debt Impact Return On Equity?

Companies usually need to invest money to grow their profits. That cash can come from retained earnings, issuing new shares (equity), or debt. In the case of the first and second options, the ROE will reflect this use of cash, for growth. 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.

Combining CSX's Debt And Its 28% Return On Equity

CSX clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.43. There's no doubt the ROE is impressive, but it's worth keeping in mind that the metric could have been lower if the company were to reduce its 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.

Conclusion

Return on equity is one way we can compare its business quality of different companies. A company that can achieve a high return on equity without debt could be considered a high quality business. If two companies have around the same level of debt to equity, and one has a higher ROE, I'd generally prefer the one with higher ROE.

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 I think it may be worth checking this free report on analyst forecasts for the company.

But note: CSX 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.
