Peeling the layers of ROE – trisecting a company’s profitability

Return on Equity (ROE) weighs Best Buy’s profit against the level of its shareholders’ equity. An ROE of 29.53% implies $0.3 returned on every $1 invested. In most cases, a higher ROE is preferred; however, there are many other factors we must consider prior to making any investment decisions.

Return on Equity = Net Profit ÷ Shareholders Equity

ROE is measured against cost of equity in order to determine the efficiency of Best Buy’s equity capital deployed. Its cost of equity is 8.63%. Since Best Buy’s return covers its cost in excess of 20.90%, its use of equity capital is efficient and likely to be sustainable. Simply put, Best Buy pays less for its capital than what it generates in return. ROE can be split up into three useful ratios: net profit margin, asset turnover, and financial leverage. This is called the Dupont Formula:

Dupont Formula

ROE = profit margin × asset turnover × financial leverage

ROE = (annual net profit ÷ sales) × (sales ÷ assets) × (assets ÷ shareholders’ equity)

ROE = annual net profit ÷ shareholders’ equity

Essentially, profit margin shows how much money the company makes after paying for all its expenses. The other component, asset turnover, illustrates how much revenue Best Buy can make from its asset base. And finally, financial leverage is simply how much of assets are funded by equity, which exhibits how sustainable the company’s capital structure is. Since financial leverage can artificially inflate ROE, we need to look at how much debt Best Buy currently has. At 32.08%, Best Buy’s debt-to-equity ratio appears low and indicates the above-average ROE is generated from its capacity to increase profit without a large debt burden.

ROE is a simple yet informative ratio, illustrating the various components that each measure the quality of the overall stock. Best Buy’s above-industry ROE is encouraging, and is also in excess of its cost of equity. Its high ROE is not likely to be driven by high debt. Therefore, investors may have more confidence in the sustainability of this level of returns going forward. ROE is a helpful signal, but it is definitely not sufficient on its own to make an investment decision.
