A Closer Look At Big Yellow Group Plc’s (LON:BYG) Impressive ROE

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. To keep the lesson grounded in practicality, we’ll use ROE to better understand Big Yellow Group Plc (LON:BYG).

Over the last twelve months Big Yellow Group has recorded a ROE of 11%. One way to conceptualize this, is that for each £1 of shareholders’ equity it has, the company made £0.11 in profit.

How Do I Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit ÷ Shareholders’ Equity

Or for Big Yellow Group:

11% = 116.298 ÷ UK£1.1b (Based on the trailing twelve months to September 2018.)

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

What Does ROE 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 profit over the last twelve months. That means that the higher the ROE, the more profitable the company is. So, all else being equal, a high ROE is better than a low one. That means ROE can be used to compare two businesses.

Does Big Yellow Group Have A Good Return On Equity?

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. As is clear from the image below, Big Yellow Group has a better ROE than the average (8.4%) in the reits industry.

That is a good sign. I usually take a closer look when a company has a better ROE than industry peers. For example, I often check if insiders have been buying shares .

The Importance Of Debt To 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 debt used for growth will improve returns, but won’t affect the total equity. That will make the ROE look better than if no debt was used.

Big Yellow Group’s Debt And Its 11% ROE

Big Yellow Group has a debt to equity ratio of 0.27, which is far from excessive. The fact that it achieved a fairly good ROE with only modest debt suggests the business might be worth putting on your watchlist. Careful use of debt to boost returns is often very good for shareholders. However, it could reduce the company’s ability to take advantage of future opportunities.

The Bottom Line On ROE

Return on equity is one way we can compare the business quality of different companies. In my book the highest quality companies have high return on equity, despite low debt. 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. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
