Tsubota Laboratory (TSE:4890) ROE % Explanation
ROE % measures the rate of return on the ownership interest (shareholder's equity) of the common stock owners. It measures a firm's efficiency at generating profits from every unit of shareholders' equity (also known as net assets or assets minus liabilities). ROE % shows how well a company uses investment funds to generate earnings growth. ROE %s between 15% and 20% are considered desirable.
The factors that affect a company's ROE % can be illustrated with the three-step DuPont Analysis:
Note:
The net income data used here is two times the semi-annual (Mar. 2026) net income data. The Revenue data used here is two times the semi-annual (Mar. 2026) revenue data. The same rule applies to Pre-Tax Income and Operating Income.
* In the five-step DuPont Analysis, Operating Income is only available for non-financial companies. Thus, for Insurance companies, we use EBIT as a substitution of Operating Income. For Banks, both Operating Income and EBIT is unavailable. Thus we combined Interest Burden and Operating Margin % into Pretax Margin %, and the DuPont Analysis is divided into four components instead.
* For Operating Data section: All numbers are indicated by the unit behind each term and all currency related amount are in USD. * For other sections: All numbers are in millions except for per share data, ratio, and percentage. All currency related amount are indicated in the company's associated stock exchange currency.
Be Aware
Net Income is used.
Because a company can increase its ROE % by having more financial leverage, it is important to watch the equity multiplier when investing in high ROE % companies. Like ROA %, ROE % is calculated with only 12 months data. Fluctuations in company's earnings or business cycles can affect the ratio drastically. It is important to look at the ratio from a long term perspective.
Asset light businesses require very few assets to generate very high earnings. Their ROE %s can be extremely high.
