It's the first profitability ratio in this level, distinct from the liquidity and debt-to-equity ratios already covered: it doesn't measure whether the company can pay its debts, but whether shareholders' capital is being put to good use.

Unlike an absolute figure, a ratio expresses a relationship: it divides one item by another to get a number comparable between companies of different sizes, between different periods, or between a company and its sector. An isolated ratio, however, rarely says enough on its own -- its real value lies in its evolution over time, in its comparison with similar companies, and in the context of the sector and business model it belongs to. When building any ratio, what exact items go into the numerator and denominator matters as much as the period they correspond to -- small methodological differences can significantly change how the result is interpreted."}},{"concept":{"id":56,"slug":"dupont-decomposition","term":"DuPont decomposition","shortDefinition":"A method that splits ROE into three factors -- margin, asset turnover, and leverage -- to understand where a company's profitability really comes from.","longDefinition":"The DuPont decomposition splits ROE into three multiplicative factors: net margin (how much profit is left from each euro of revenue), asset turnover (how much revenue each euro of assets generates, a measure of efficiency), and financial leverage (how much of the assets are financed with debt relative to equity). Multiplied together, these three factors exactly reconstruct ROE. Its usefulness lies in the fact that two companies can have the same ROE for completely different reasons -- one from selling with a high margin, another from being very efficient with its assets, another from being more leveraged -- and DuPont lets you tell which of those stories is the real one, instead of settling for a single figure that blends them all together."}},{"concept":{"id":58,"slug":"roic","term":"ROIC","shortDefinition":"The after-tax return a company generates on all the capital invested in its business -- debt and equity together -- regardless of how it's financed.","longDefinition":"ROIC (Return on Invested Capital) measures how much after-tax operating income a company generates in relation to all the capital invested in its business -- financial debt and equity together, without distinguishing which of the two it comes from. After-tax operating income is used, not gross operating income or net income: gross would ignore the real effect of taxes on profitability, and net income would carry the effect of how the company is financed (interest on debt), exactly what ROIC seeks to isolate. Unlike ROE, which only compares profit with equity, ROIC doesn't change if a company decides to finance itself with more debt and less of its own capital, or vice versa -- it measures the performance of the business itself, not the effect the financing structure has on that performance. That's why ROIC complements ROE instead of replacing it: ROE says how much the shareholder earns on their capital; ROIC says how much the business earns per euro employed in it, whoever that euro belongs to."}}],"calculatedBy":[{"concept":{"id":45,"slug":"equity","term":"Equity","shortDefinition":"The part of a company that belongs to its shareholders -- what's left of assets after subtracting all liabilities.","longDefinition":"Equity (shareholders' equity) is the part of a company that belongs to its own shareholders: what's left of assets after subtracting all liabilities.

This lesson turns that mechanism into a concrete interpretation criterion -- the most important limitation of ROE as an isolated metric.\n\nThe first limitation, already hinted at, is that leverage alone can inflate ROE without the business being more efficient. A company that increases its debt to finance more assets, without improving either its margin or its asset turnover, sees its ROE rise purely from the multiplying effect of leverage. That higher ROE doesn't represent a real improvement in the business -- it represents more financial risk taken on. Breaking ROE down with DuPont is precisely what lets you distinguish this situation from a genuine improvement in efficiency or margin.\n\nThe second limitation is that a point-in-time ROE value, just as already seen with the liquidity and debt-to-equity ratios in Module 5, says little on its own. Its evolution over time matters -- a stable or growing ROE tells a different story than one that only holds up for a quarter thanks to a non-recurring item, already covered in Module 2. And, as with any financial ratio, it matters to compare it with companies in the same sector: a ROE of 12% can be outstanding in a capital-intensive sector and mediocre in another with much lighter capital structures.\n\nThe third, subtler limitation is that ROE says nothing about whether that return compensates for the risk the shareholder takes on. Two companies with the same ROE can have very different risk profiles if one is much more leveraged than the other -- ROE alone doesn't incorporate that difference in risk, only the return.\n\nWith this lesson, the module closes. The next module in this level introduces ROIC, a profitability ratio that complements ROE by looking at the return on all invested capital -- debt and equity together -- not just on equity.\n\n## Example\n\nA company that doubles its debt from one year to the next without changing its real business can see its ROE rise notably -- breaking it down with DuPont reveals that the jump comes entirely from leverage, not from an improvement in margin or asset turnover.\n\n## Common mistakes\n\n- Judging a company as excellent just for having a high ROE, without breaking it down to check whether it comes from real efficiency or leverage.\n- Comparing the ROE of companies in very different sectors without adjusting for the level of leverage and risk each one takes on, the same mistake already seen when comparing liquidity and debt-to-equity ratios in Module 5.\n\n## Summary\n\nROE has three important limitations: it can be inflated by leverage without reflecting real efficiency, a point-in-time value says little without looking at its evolution and sector comparison, and it doesn't incorporate the risk the shareholder takes on to achieve that return.
