That is a good sign. Bear in mind, a high ROE doesn't always mean superior financial performance. Aside from changes in net income, a high ROE can also be the outcome of high debt relative to equity, which indicates risk.

Why You Should Consider Debt When Looking At ROE

Companies usually need to invest money to grow their profits. That cash can come from retained earnings, issuing new shares (equity), or debt. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Combining Kohjin Bio's Debt And Its 13% Return On Equity

Although Kohjin Bio does use debt, its debt to equity ratio of 0.38 is still low. The combination of modest debt and a very respectable ROE suggests this is a business worth watching. Judicious use of debt to improve returns can certainly be a good thing, although it does elevate risk slightly and reduce future optionality.

Summary

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. Companies that can achieve high returns on equity without too much debt are generally of good quality. All else being equal, a higher ROE is better.

But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
