Should You Expect Comerica Incorporated (NYSE:CMA) To Continue Delivering An ROE Of 11.70%?

I am writing today to help inform people who are new to the stock market and want to begin learning the link between company’s fundamentals and stock market performance.

Comerica Incorporated (NYSE:CMA) delivered an ROE of 11.70% over the past 12 months, which is an impressive feat relative to its industry average of 8.69% during the same period. Though, the impressiveness of CMA’s ROE is contingent on whether this industry-beating level can be sustained. Sustainability can be gauged by a company’s financial leverage – the more debt it has, the higher ROE is pumped up in the short term, at the expense of long term interest payment burden. Let me show you what I mean by this.

What you must know about ROE

Firstly, Return on Equity, or ROE, is simply the percentage of last years’ earning against the book value of shareholders’ equity. An ROE of 11.70% implies $0.12 returned on every $1 invested, so the higher the return, the better. Investors seeking to maximise their return in the Regional Banks industry may want to choose the highest returning stock. But this can be misleading as each company has different costs of equity and also varying debt levels, which could artificially push up ROE whilst accumulating high interest expense.

ROE is assessed against cost of equity, which is measured using the Capital Asset Pricing Model (CAPM) – but let’s not dive into the details of that today. For now, let’s just look at the cost of equity number for Comerica, which is 9.80%. Since Comerica’s return covers its cost in excess of 1.90%, its use of equity capital is efficient and likely to be sustainable. Simply put, Comerica 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:

Essentially, profit margin shows how much money the company makes after paying for all its expenses. Asset turnover shows how much revenue Comerica can generate with its current 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. We can assess whether Comerica is fuelling ROE by excessively raising debt. Ideally, Comerica should have a balanced capital structure, which we can check by looking at the historic debt-to-equity ratio of the company. The most recent ratio is 69.82%, which is sensible and indicates Comerica has not taken on too much leverage. Thus, we can conclude its above-average ROE is generated from its capacity to increase profit without a large debt burden.

Next Steps:

ROE is a simple yet informative ratio, illustrating the various components that each measure the quality of the overall stock. Comerica’s above-industry ROE is encouraging, and is also in excess of its cost of equity. ROE is not likely to be inflated by excessive debt funding, giving shareholders more conviction in the sustainability of high returns. ROE is a helpful signal, but it is definitely not sufficient on its own to make an investment decision.
