While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. To keep the lesson grounded in practicality, we'll use ROE to better understand STORAGE-OH Co.,Ltd. (TSE:2997).
Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.
ROE can be calculated by using the formula:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for STORAGE-OHLtd is:
12% = JP¥118m ÷ JP¥993m (Based on the trailing twelve months to October 2025).
The 'return' is the income the business earned over the last year. So, this means that for every ¥1 of its shareholder's investments, the company generates a profit of ¥0.12.

One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As is clear from the image below, STORAGE-OHLtd has a better ROE than the average (8.7%) in the Commercial Services industry.
That is a good sign. Bear in mind, a high ROE doesn't always mean superior financial performance. Especially when a firm uses high levels of debt to finance its debt which may boost its ROE but the high leverage puts the company at risk.

Virtually all companies need money to invest in the business, to grow profits. That cash can come from issuing shares, retained earnings, or debt. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the use of debt will improve the returns, but will not change the equity. That will make the ROE look better than if no debt was used.
It appears that STORAGE-OHLtd makes extensive use of debt to improve its returns, because it has an alarmingly high debt to equity ratio of 3.87. Its ROE is respectable, but it's not so impressive once you consider all of the debt.
Return on equity is useful for comparing the quality of different businesses. In our books, the highest quality companies have high return on equity, despite low debt. If two companies have around the same level of debt to equity, and one has a higher ROE, I'd generally prefer the one with higher ROE.
Having said that, while ROE is a useful indicator of business quality, you'll have to look at a whole range of factors to determine the right price to buy a stock. The rate at which profits are likely to grow, relative to the expectations of profit growth reflected in the current price, must be considered, too.
