Can Southern Copper Corporation's (NYSE:SCCO) ROE Continue To Surpass The Industry Average?

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 Southern Copper Corporation (NYSE:SCCO), by way of a worked example.

Our data shows Southern Copper has a return on equity of 22% for the last year. One way to conceptualize this, is that for each $1 of shareholders' equity it has, the company made $0.22 in profit.

How Do You Calculate ROE?

The formula for ROE is:

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

Or for Southern Copper:

22% = US$1.5b ÷ US$6.9b (Based on the trailing twelve months to December 2019.)

It's easy to understand the 'net profit' part of that equation, but 'shareholders' equity' requires further explanation. It is the capital paid in by shareholders, plus any retained earnings. The easiest way to calculate shareholders' equity is to subtract the company's total liabilities from the total assets.

What Does Return On Equity Mean?

Return on Equity measures a company's profitability against the profit it has kept for the business (plus any capital injections). The 'return' is the amount earned after tax over the last twelve months. That means that the higher the ROE, the more profitable the company is. So, all else equal, investors should like a high ROE. That means it can be interesting to compare the ROE of different companies.

Does Southern Copper Have A Good Return On Equity?

One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. Pleasingly, Southern Copper has a superior ROE than the average (13%) company in the Metals and Mining industry.

That's clearly a positive. We think a high ROE, alone, is usually enough to justify further research into a company. For example, I often check if insiders have been buying shares.

How Does Debt Impact ROE?

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. That will make the ROE look better than if no debt was used.

Combining Southern Copper's Debt And Its 22% Return On Equity

Southern Copper clearly uses a significant amount of debt to boost returns, as it has a debt to equity ratio of 1.01. While the ROE is impressive, that metric has clearly benefited from the company's 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.

But It's Just One Metric

Return on equity is one way we can compare the 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. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
