Can Aptiv PLC's (NYSE:APTV) ROE Continue To Surpass The Industry Average?

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. By way of learning-by-doing, we'll look at ROE to gain a better understanding of Aptiv PLC (NYSE:APTV).

Aptiv has a ROE of 27%, based on the last twelve months. Another way to think of that is that for every $1 worth of equity in the company, it was able to earn $0.27.

How Do You Calculate ROE?

The formula for ROE is:

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

Or for Aptiv:

27% = US$1.0b ÷ US$3.8b (Based on the trailing twelve months to September 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 Signify?

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 yearly profit. The higher the ROE, the more profit the company is making. So, as a general rule, a high ROE is a good thing. That means ROE can be used to compare two businesses.

Does Aptiv 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 is clear from the image below, Aptiv has a better ROE than the average (14%) in the Auto Components industry.

That is a good sign. In my book, a high ROE almost always warrants a closer look. For example you might check if insiders are buying shares.

The Importance Of Debt To Return On Equity

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. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Aptiv's Debt And Its 27% ROE

It's worth noting the significant use of debt by Aptiv, leading to its debt to equity ratio of 1.15. 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.

The Key Takeaway

Return on equity is useful for comparing the quality of different businesses. 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.

Having said that, while ROE is a useful indicator of business quality, you'll have to look at a whole range of factors to determine the right price to buy a stock. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider. So I think it may be worth checking this free report on analyst forecasts for the company.
