This analysis is intended to introduce important early concepts to people who are starting to invest and want to begin learning the link between company’s fundamentals and stock market performance.
Alumina Limited (ASX:AWC) delivered an ROE of 23.5% over the past 12 months, which is an impressive feat relative to its industry average of 12.6% during the same period. Superficially, this looks great since we know that AWC has generated big profits with little equity capital; however, ROE doesn’t tell us how much AWC has borrowed in debt. Today, we’ll take a closer look at some factors like financial leverage to see how sustainable AWC’s ROE is.

Peeling the layers of ROE – trisecting a company’s profitability
Return on Equity (ROE) is a measure of Alumina’s profit relative to its shareholders’ equity. For example, if the company invests A$1 in the form of equity, it will generate A$0.24 in earnings from this. 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
Returns are usually compared to costs to measure the efficiency of capital. Alumina’s cost of equity is 9.9%. This means Alumina returns enough to cover its own cost of equity, with a buffer of 13.6%. This sustainable practice implies that the company 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
Basically, profit margin measures how much of revenue trickles down into earnings which illustrates how efficient the business is with its cost management. Asset turnover reveals how much revenue can be generated from Alumina’s asset base. Finally, financial leverage will be our main focus today. It shows how much of assets are funded by equity and can show how sustainable the company’s capital structure is. Since financial leverage can artificially inflate ROE, we need to look at how much debt Alumina currently has. The debt-to-equity ratio currently stands at a low 5.1%, meaning the above-average ROE is due to its capacity to produce profit growth without a huge debt burden.
Next Steps:
While ROE is a relatively simple calculation, it can be broken down into different ratios, each telling a different story about the strengths and weaknesses of a company. Alumina’s ROE is impressive relative to the industry average and also covers 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.
