How well the company turns shareholders' money into profit.
What this return is
ROE · Return on Equity measures a company's profitability relative to its owners' money: net income ÷ shareholders' equity. A 18% return means every $100 of shareholder money produced $18 in profit. It shows how efficiently the machine runs its capital.
Reading its levels
A chronic level above 15% suggests a competitive moat that protects profitability from erosion, and below 8% it raises the question of whether capital should be there at all. Stability matters more than the peak: ten years at 17% says more than a single jump to 30%.
The leverage trap buried in it
The denominator is shareholders' equity, and debt shrinks it. A company with average assets and heavy leverage shows a shiny but fragile return on equity. So it is read together with return on assets and with leverage: a high return from efficient assets is not the same as a high return built on debt.
Hypothetical example
Two companies with a 20% return on equity. The first has almost no debt and a return on assets of 16%. The second has threefold leverage and a return on assets of 6%. In a year of tightening and rising interest, the first keeps going while debt eats away the second's shine. The identical number was two different stories.
Common mistake
Ignoring buybacks: heavy repurchases shrink equity and inflate the return arithmetically with no operating improvement. A look at the path of equity itself exposes the trick.
The trap in its denominator
Return on equity can be pushed up artificially by shrinking the denominator: a company that borrows to buy back its shares reduces equity, and the return jumps with no improvement in operations. That is why it is always broken into its three components (profit margin × asset turnover × leverage). If the rise comes from margin or turnover, it is a real improvement. If it comes from leverage, it is risk dressed up as efficiency.
Where to see it on the platform
The sector comparisons show it next to its siblings (return on assets, leverage) from SEC filings, so efficiency is read without masks.
The sector comparison module shows it with financial leverage in the same view, so it is not read apart from its source.
