How to Use ROE and ROA in Stock Analysis

Last Updated on June 6, 2023

ROE and ROA are two financial ratios that are crucial in analyzing the performance of stocks. ROE stands for Return on Equity, while ROA stands for Return on Assets. In layman’s terms, ROE measures how efficiently a company is using its shareholders’ equity to generate profit. On the other hand, ROA measures how efficiently a company is utilizing its assets to generate revenue.

How to Use ROE and ROA in Stock Analysis

It’s vital to understand ROE and ROA in stock analysis as they reveal a company’s financial health. A high ROE signifies effective use of shareholders’ equity, while a low one may indicate poor financial management. Similarly, a high ROA shows efficient revenue generation from assets, whereas a low ROA could suggest poor asset use or inefficient operations.

Investors and analysts often use ROE and ROA in combination with other metrics, such as earnings per share, revenue growth, and price-to-earnings ratio, to gain a comprehensive view of a company’s performance. By examining these financial ratios, investors and analysts can make informed decisions about whether to buy, hold, or sell stocks.

Definition of ROE and ROA

Return on equity (ROE) and return on assets (ROA) are useful financial metrics that can help investors evaluate a company’s profitability and efficiency. When used together, ROE and ROA can provide a clearer picture of a company’s financial health and its ability to generate profits for its shareholders. In this blog post, we will define ROE and ROA, discuss their formulas, and explain how investors can use them in stock analysis.

  • ROE – Return on equity is a measure of a company’s profitability relative to the amount of equity shareholders have invested. It represents the amount of net income a company earns for each dollar of shareholder equity.

  • ROA – Return on assets is a measure of a company’s profitability relative to its total assets. It represents the amount of net income a company earns for each dollar of assets on its balance sheet.

Formula for ROE

The formula for ROE is:

ROE = Net Income / Shareholder Equity

Net income is the amount of profit a company earns after deducting all expenses and taxes. Shareholder equity represents the amount of money that shareholders have invested in the company, which includes both capital contributions and retained earnings.

Formula for ROA

The formula for ROA is:

ROA = Net Income / Total Assets

Net income is the same as in the ROE formula, and total assets represent the sum of a company’s short- and long-term assets as reported on its balance sheet.

Using ROE and ROA in Stock Analysis

ROE and ROA are useful metrics for investors to consider when researching potential investments. When used together, these metrics can give a clearer picture of a company’s financial health and its ability to generate profits for shareholders. Here are a few ways investors can use ROE and ROA in stock analysis:

Comparing ROE to industry benchmarks:

Investors can use industry benchmarks to compare a company’s ROE to its peers. This can help them determine whether a company is generating competitive returns, or whether it is underperforming compared to its industry.

Evaluating a company’s profitability:

ROE and ROA can help investors evaluate a company’s profitability and efficiency. A company with a high ROE and ROA may be generating strong profits relative to its invested capital, while a company with low ROE and ROA may be struggling to generate profits.

Identifying trends over time:

Investors can use ROE and ROA to track a company’s performance over time. By comparing a company’s current ROE and ROA to its historical metrics, investors can identify improving or declining profitability and make informed investment decisions.

Identifying potential red flags:

Low or declining ROE and ROA can be a red flag for investors, as they may indicate that a company is struggling to generate profits. Investors should look for additional information to determine whether these metrics are the result of temporary factors or more long-term issues.

While ROE and ROA are useful metrics in stock analysis, they should not be used in isolation. Investors should consider a variety of factors when researching potential investments, including a company’s competitive environment, management quality, and financial stability. By using ROE and ROA in conjunction with other financial metrics, investors can gain a more complete understanding of a company’s financial health and make more informed investment decisions.

Difference between ROE and ROA

Return on Equity (ROE) and Return on Assets (ROA) are two of the most commonly used financial ratios that are used by investors and analysts to evaluate the financial performance of a company. Although both of these ratios are used to measure the profitability of a company, they have significant differences that make them unique and are used for different purposes.

Explanation of the difference between the two ratios

ROE and ROA are both used to measure the profitability of a company, but they measure it in different ways.

ROE measures the amount of profit generated by a company in relation to the amount of shareholder equity invested in the company. This ratio measures how much profit a company is generating with the money invested by its shareholders.

On the other hand, ROA measures the amount of profit generated by a company in relation to its total assets. This ratio measures how much profit a company is generating with all of its assets, including both short-term and long-term assets.

It is important to note that ROE is a more focused ratio as it only considers the return generated on equity investment whereas ROA considers all the total assets of the company.

When to use one over the other

Both ratios effectively assess a company’s financial performance, yet serve different purposes.

Investors focused on high equity returns value ROE. Companies boasting high ROE ratios usually attract these investors, as high returns signal efficient use of shareholder funds.

Investors typically use ROA to compare companies within the same industry. Asset types can vary between companies, making ROA a more effective profitability comparison tool. ROA measures profitability on a broader scale, considering all company assets. It accurately shows the efficiency of a company in using assets to generate profit.


Investors and analysts use both ROE and ROA to evaluate a company’s financial performance, but they differ significantly. ROE focuses on the return on equity investment, while ROA considers all company assets. The choice between the two ratios depends on the analysis purpose and context.

Interpretation of ROE and ROA

ROE (Return on Equity) and ROA (Return on Assets) are both important financial ratios that investors and analysts use to evaluate a company’s financial performance. Understanding how to interpret these ratios can be the key to making informed investment decisions in the stock market.

  • A high ROA indicates that a company is generating significant profits relative to its overall assets.

  • ROA is a valuable tool for comparing the performance of companies in the same industry since it takes into account the size of a company.

  • For example, service-based companies with low asset levels may have high ROAs, while manufacturing companies with high asset levels may have lower ROAs.

Importance of Industry Comparison

To assess a company’s financial health, you should examine two crucial ratios: Return on Equity (ROE) and Return on Assets (ROA). These ratios reveal a company’s efficiency in using assets and shareholder equity to generate profits. However, a comparative analysis with industry peers is crucial for a comprehensive understanding of the company’s performance.

  • Comparing a company’s financial ratios to others in its industry provides a better perspective on its financial health.

  • ROE and ROA can vary significantly between industries, so industry-specific benchmarks are essential for accurate comparisons.

  • Industry comparisons also help identify a company’s position within the industry and its competitiveness.

Without comparing a company’s ratios to others within an industry, it is impossible to know if the company’s performance is meeting or exceeding industry standards. Compared to a company with lower ROE and ROA, a company with higher ratios may seem like a better investment. However, if that company has relatively low ratios compared to others within the same industry, it may not be performing as well as it seems.

How to Find Industry Benchmarks

  • Industry-based financial databases and reports such as Bloomberg Industry Ratios or Almanac of Business and Industrial Financial Ratios provide industry-specific benchmarks.

  • Most companies release annual reports that include industry comparisons or ratios that provide industry benchmarks.

  • Financial analysts and investment professionals specializing in a particular industry can provide industry-specific financial content.

Industry benchmarking is time-consuming, but it is crucial to ensure accurate and meaningful data to make better investment decisions. Most analysts use multiple sources to ensure more accurate industry comparisons, avoiding potential biases in a single benchmark data source.

Limitations of Industry Benchmarking

While industry benchmarking is essential, it does have its limitations.

  • Industry benchmarks do not eliminate the need to perform individual company analysis.

  • Benchmarks may not be relevant to a particular company’s stage of development or unique business model.

  • Industry benchmarks may be influenced by external factors such as regulatory changes, economic conditions, and technology advancements.

Therefore, industry comparisons should always be used in conjunction with other financial analysis tools for a comprehensive understanding of a company’s financial performance.


ROE and ROA are essential financial ratios that provide insight into a company’s financial health. However, these ratios should not be viewed in isolation when making investment decisions. It is always necessary to compare a company’s ratios to others within the same industry to better understand its position in the industry and its competitiveness. Industry benchmarking is time-consuming but critical to ensure accurate and meaningful data.

Nevertheless, industry benchmarks should not be the only criteria for making investing decisions. It is good practice to use industry benchmarks alongside other financial analysis tools to obtain a complete picture of a company’s financial performance.

Conclusion

ROE and ROA are two important ratios in stock analysis. ROE measures the profitability of a company by evaluating how much profit it generates in relation to its shareholder’s equity, while ROA measures how efficiently a company can generate income using its assets.

These two ratios are valuable tools for investors to use when making investment decisions. By comparing these ratios across companies and industries, investors can gain a deeper understanding of a company’s financial health and performance.

When using ROE and ROA in stock analysis, it is important to consider other factors such as the company’s debt, revenue growth, and industry trends. Investors should also look beyond just the numbers and consider the company’s management, competitive advantage, and future prospects.

Overall, ROE and ROA can provide valuable insights for investors looking to make informed investment decisions. However, it is important to use them in conjunction with other financial ratios and qualitative factors to develop a comprehensive analysis of a company’s potential.
