🎯Why ROE matters ?

📘 The ROE is a general indicator of firm's global profitability. It is the overall profitability obtained by the company from all the management areas (operational, financial, ancillary, taxes). Return on Equity (ROE) is one of the most powerful and widely used financial ratios for evaluating a company’s profitability and efficiency. At its core, ROE measures how effectively a company uses the equity provided by its shareholders to generate profits. Unlike individual ratios that only capture operational or financial dimensions, ROE is a global indicator of profitability. It incorporates the combined results of a company’s operations, financial strategy, taxation, and ancillary activities.

🎯 Definition

it is a profitability ratio for company's shareholders

✅ The Return on Equity (ROE) expresses what is the degree of remuneration of a company's equity, hence it reflects the return earned on the stockolders' investment (resources that over time shareholders have made or left in the company – without withdrawing profits –). This makes ROE particularly important for analysts and traders, as it reveals both the return shareholders are receiving on their investment and the risks associated with the company’s capital structure.

✅ Net Income: Profit remaining after deducting operating expenses, interest, taxes, and ancillary costs.

✅Shareholders’ Equity: The net resources contributed by shareholders, either through paid-in capital or retained earnings that have not been distributed as dividends.

For shareholders and traders, ROE represents the return on invested capital without considering external financing. A high ROE indicates that management is effectively deploying shareholders’ resources to create profits, while a low or declining ROE may signal inefficiencies, poor asset utilization, or rising costs of financing. ROE serves as a bridge between profitability and financial structure, since both earnings performance and capital allocation influence it.

🔍 Relation with Dupont formula

It is generally known that high level of performance (i.e. when the ROI is above industry average) will produce a high return to equity holders.

However, companies that suffer of low performance (with ROI under average) can still produce above average return to stockholders' equity (ROE). This can be achieved through borrowed funds that according with the DUPONT formula keep higher equity multiplier.

📌 Financial Leverage Analysis

The financial leverage is used to measure the financial risk that arise from the presence of debt and/or class of preferred shares in the company's capital structure.

ROE 🟰 ROI ➕ (ROI ➖ ROD) ✖ (Debt ➗ Equity)

📘 Spread ROI - ROD

The ROD must always be compared with the company's ROI for the purpose of a profitability analysis that considers the structural dynamics of the company as a whole. This indicator expresses the profitability of capital borrowed (financed) from the company by lenders and third parties indicating in percentage terms the cost of capital the company must reimburs to its lenders. In finance, this indicator is also considered as the average cost of pre-tax third-party capital and it is very important when assessing the economic and financial sustainability of the company.

The spread between ROI and ROD expresses the differential between the return on invested capital (ROI) and the cost of borrowed captains (ROD). And the D/E debt ratio has even a multiplier effect on both earnings and losses.
When the ROI > ROD the company could make further investments financed with third-party capital (typically of banks) and not venture capital because only in a potential leverage situation (or positive spread of profitability), in this sense the company can be bankable. On the other hands, when the ROI > ROD, the debt ratio acts as a multiplier increasing the ROE. This is a positive situation for the company where the company can leverage for the enterprise business.

When the ROI < ROD it means that the company is buying its resources with the capital of third parties resulting in a low profitability and in such cases the ROE decreases with the increase in the debt ratio indicated as the ratio of financial debts (capital of onerous third parties) to equity (own funds). So that a situation where the ROI – ROD < 0 the company must focus on the use of equity as a financing capital because in a pre-existing debt situation, the latter produces only an increase in the cost of credit capital, resulting in the profitability of invested capital (ROI) and therefore its financial risk.

📘 Interpretations

One critical aspect of ROE is its relationship with financial leverage—the use of debt (and sometimes preferred shares) in a company’s capital structure.

✅ Leverage amplifies returns: When a company uses debt effectively, it can increase ROE because borrowed funds are used to generate additional profits without increasing equity.

✅ But leverage increases risk: Excessive debt raises fixed obligations (interest payments), increasing financial risk and the chance of insolvency.

The presence of preferred shares also adds a layer of leverage since they represent a fixed cost (preferred dividends) before common shareholders are compensated.

👉 Thus, while higher leverage may boost ROE in the short term, analysts must assess whether this improvement comes from genuine profitability or simply from taking on more risk.

The ROE is used in the financial leverage analysis as it helps to understand what could be the optimal policy of composition of funding sources (financing capital) that have been able to meet the financing requirements generated by the capital employment structure.

As we can see above, the formula ties the company's ROI and its degree of financial leverage which is the actual use of borrowed funds in a certain moment in time.

Within the formula arise the "equity multiplier" which gives an indication of the extend to which a company asset is financed by stockholders or by third party funders. In fact when the "equity multiplier" is equal to 1 the ROI and the ROE are the same. Differently, when the company has a financial leverage due capital supplied by creditors which is equal to (1 - Debt ratio).

It must always be considered that for the Return on Equity, there are no optimal values. To this purpose is always useful to compare the ROE with comparable or other's company operating in the industry finding it with a compelling benchmark analysis. In fact, the ROE cannot ignore the reference sector as it must be sufficient to reward both the general risk of carrying out the business as well as the specific risk associated with the characteristics of the reference sector.

If there are significant changes in equity from one year to the next (revaluation reserves, increased share capital, assets contribution for future capital increases by shareholders), it could be misleading to use the ROE indicator, this can be monitored with the Change in equity ratio.

The adjusted" ROE

This ratio is an adjustment and it gives in percentage terms the net profitability of the equity's book value adjusted. As we know, the equity's book value account also dividends in the retained earnings subaccount. So, the ROE Adjusted wants to take out any transaction in the benefit of the company's stockholders where is a dividend or is capital injection as shareholding financing.

The ratio is between the net income and the adjusted equity as per the following formula:

NET INCOME ➗ (EQUITY'S BOOK VALUE ➖ DIVIDENDS ➖ SHAREHOLDING FINANCING)

✅ Conclusion

Although it provides a statistic on historical path of the company returns and for financial analyst can be considered a "basic" static approach. The ROE determines what is the value in percentage terms that the net profit shall returns to the shareholders indicating the overall company profitability for the owned assets used by the management in the operation of the business.

ROE expresses the degree of remuneration of a company’s equity, answering the question:
👉 How much profit does the company generate for every unit of shareholder equity?

It is inevitable that on average the ROE shall be at least higher than the return on risk-free investments (such as government bonds) for potential investors to see company shares with a positive risk-premium. As a fact of the matter, the ROE values in percentage terms the degree of remuneration in favour of shareholders for their capital invested in the company.

The community of creditors might be more interested to obtain a dynamic ROE that uses an average value at its denominator between the beginning of the year and the end of the financial year. This is because in order to ascertain the profitability of the company's equity (own assets or equity) it is more correct to average the initial value with the final value of the equity in a given period of time.

ROE is far more than a simple profitability ratio—it is a global performance indicator that reflects how well management is generating value for shareholders with the resources entrusted to them.

For analysts and traders, mastering ROE analysis means not just calculating the ratio, but also interpreting its drivers, sustainability, and relationship with financial risk. By understanding the interplay between profitability, asset efficiency, and leverage, market participants can better evaluate companies, anticipate risks, and make informed investment decisions.

Here are two visual teaching aids:

DuPont Breakdown Chart – showing how ROE is the product of profit margin, asset turnover, and financial leverage.

Leverage Impact Graph – illustrating how increasing the debt-to-equity ratio can amplify ROE (but also increase risk).

DuPont Analysis:

Net Profit Margin (Net Income / Sales): Shows operational efficiency and profitability from sales.
Asset Turnover (Sales / Total Assets): Indicates how effectively the company uses its assets to generate revenue.
Equity Multiplier (Total Assets / Shareholders’ Equity): Measures financial leverage, reflecting how much of the assets are financed by equity versus debt.

This decomposition allows analysts to see whether ROE is being driven primarily by operational strength, asset utilization, or leverage.

💡Key Insights for Analysts and Traders

ROE as a holistic measure: It captures overall profitability by integrating operational performance, financial management, and tax efficiency.
Sustainability check: A consistently high ROE driven by strong margins and efficient asset use is more sustainable than one inflated by leverage.
Comparability: ROE should always be compared within the same industry, as capital intensity and leverage norms vary significantly.
Red flags: A rising ROE accompanied by a falling equity base or excessive leverage may indicate financial fragility rather than genuine value creation.
Long-term perspective: For traders, ROE trends over time are more informative than single-period values. A stable and improving ROE signals strong management practices and attractive long-term returns.
