What is Return on Equity (ROE)?
Return on Equity (ROE) shows how much profit a company makes using the money invested by its shareholders. It is calculated by dividing the company’s annual net income by its total shareholders’ equity and is expressed as a percentage. In simple words, ROE tells investors how many dollars of profit are generated for every dollar of shareholders’ money.
Basic Formula
- ROE = Net Income ÷ Shareholders’ Equity
- Shareholders’ equity includes share capital plus retained earnings.
Alternative Understanding of ROE
ROE can also be understood through a company’s dividend policy. If a company retains more earnings instead of paying dividends and uses them effectively, its ROE tends to be higher. This approach links the income statement (profits) with the balance sheet (equity), making ROE a two-part measure of performance.
Simple Meaning
If a company has an ROE of 10%, it means the company earns 10 cents of profit for every 1 dollar of shareholders’ equity.
Related Valuation Measures
- Price-to-Book (P/B) Ratio = Stock Price ÷ Book Value per Share
- ROE = Net Income ÷ Average Shareholders’ Equity
The book value per share is calculated by dividing total shareholders’ equity by the number of outstanding shares.
Relationship Between ROE and P/B Ratio
Companies with higher growth and stronger profitability generally have higher P/B ratios. This is because investors are willing to pay more than book value for firms that generate high returns from their equity.
Simple Example
- If a company has equity of USD 100 million and earns USD 20 million in profit, its ROE is 20%.
- Investors may value such a company at 2–3 times its book value because of its strong profitability.
Real-World Illustration (Simplified)
A well-known company once recorded an ROE of about 25% and traded at three times its book value. When its ROE later declined into negative territory, investors lost confidence and the stock price fell close to its book value. This shows how strongly ROE influences market valuation.
Important Clarification
- A high P/B ratio does not always guarantee a high ROE, but
- A consistently low P/B ratio often signals weak ROE and poor asset performance.
Key Takeaway
ROE measures how effectively a company uses shareholders’ money to generate profits. Investors prefer companies with strong and stable ROE, and this preference often leads to higher share prices and higher P/B ratios, especially for well-managed and Shari’ah-compliant firms.
