Do you often face decision paralysis when investing? With so many stocks to choose from, many people fall into the trap of blindly picking stocks, often ending up with companies that have unstable performance. Return on Equity (ROE) can help you quickly filter out businesses with true profitability. By analyzing ROE, you can determine whether a company has the ability to consistently create value. Scientific stock selection relies on data and logic, not following trends or gut feelings.

Key Points

• ROE (Return on Equity) is a critical metric for evaluating a company’s profitability. A high ROE typically indicates that a company can effectively use shareholders’ funds to generate profits.
• When selecting stocks, pay attention to ROE values. An ROE above 15% is considered excellent, 10% to 15% is good, and below 10% requires caution.
• When comparing ROE across different industries, consider industry characteristics. The technology sector often has higher ROE, while the food industry tends to have lower ROE.
• Combining ROE with Free Cash Flow (FCF) analysis provides a more comprehensive view of a company’s financial health and sustained profitability.
• Avoid relying solely on ROE; combine it with other financial metrics like Price-to-Earnings (P/E) ratio and Earnings Per Share (EPS) to more accurately assess a company’s investment value.

Risks of Blind Stock Picking

Investment Pitfalls

When investing in stocks without a scientific approach, you’re likely to fall into the trap of blind stock picking. Many investors focus only on hot sectors or follow market rumors, often overlooking a company’s actual operational performance. You might impulsively buy a stock without analyzing its financial data or profitability. This exposes you to multiple risks. According to the latest investment research, random stock picking exposes you to two main types of risks:

• Systematic Risk: This risk stems from the broader market, such as inflation, interest rate changes, wars, economic recessions, currency fluctuations, and market crashes. You cannot fully mitigate systematic risk through diversification.
• Unsystematic Risk: This risk is specific to individual companies, such as management changes, declining sales, or loss of market share. You can reduce unsystematic risk by holding a diversified stock portfolio.

If you ignore these risks and buy stocks based solely on feelings or trends, you may ultimately face significant losses.

Stock Selection Confusion

Faced with hundreds or thousands of stocks, you might feel overwhelmed and unsure where to start. You may notice that many companies appear to have strong performance on the surface, but their actual profitability is unstable. You might ask yourself: Which stock should I pick? Why do some companies’ stock prices rise quickly but then fall just as fast? Blind stock picking makes it hard to identify companies with true long-term value. You need a scientific approach to stock selection to make informed decisions in a complex market environment. Only by developing a systematic analytical mindset can you effectively avoid investment pitfalls and improve your investment success rate.

What is ROE?

ROE Definition

When analyzing a company, ROE (Return on Equity) is a highly important financial metric. ROE helps you understand how effectively a company uses shareholders’ funds to generate profits.

• ROE is a financial ratio that indicates how effectively a company uses shareholders’ equity to generate profits.
• It is calculated based on net income and shareholders’ equity, typically over a financial reporting year.
• ROE can be used to compare the profitability of companies within the same industry.
• In regulated retail rates, ROE represents the profit margin a company can earn on its invested equity.
• ROE is also a key component in calculating the total revenue required by utility companies to ensure continued operations and services.

ROE Calculation

You can calculate ROE using a simple formula.

You only need to find the company’s annual net income and shareholders’ equity data, then divide net income by shareholders’ equity to obtain the ROE value. The higher this value, the stronger the company’s ability to generate profits using shareholders’ funds.

ROE’s Role

When selecting stocks, ROE can help you quickly identify high-quality companies.

• ROE evaluates a company’s profitability by dividing its net income by shareholders’ equity.
• This metric measures a company’s ability to generate profits from shareholders’ investments.
• A higher ROE typically indicates a more profitable company, aligning with the characteristics of high-quality companies.
• Industry-wide performance affects ROE. You can compare a company’s ROE to the industry average to highlight its competitive position.
• Factors like market trends, regulatory changes, and technological advancements also affect ROE, requiring you to make comprehensive judgments.

If you master the definition, calculation, and role of ROE, you can analyze company value more scientifically and improve your stock-picking ability.

How to Use ROE for Stock Selection

ROE Reasonable Range

When selecting stocks, you should first focus on a company’s ROE value. Generally, an ROE above 15% is considered excellent, 10% to 15% is good, and below 10% requires caution. Consistently high ROE indicates that the company’s management can effectively use shareholders’ funds to generate profits. You can observe the company’s ROE changes over the past few years. If ROE is consistently rising, it suggests stable operations. If ROE shows a significant decline, it may indicate issues with profitability or operational efficiency.

A consistently high or rising ROE typically indicates effective management and robust business practices. A declining ROE may suggest potential issues within the company.

Industry Comparison

When comparing ROE across companies, you cannot rely solely on absolute values. ROE levels vary significantly across industries. The technology sector typically has the highest ROE due to low fixed assets, short lifecycles, and low overhead costs. The automotive industry has moderate ROE, as it requires significant fixed asset investments and longer asset return periods. The food industry has the lowest ROE due to intense competition and low profit margins.

When comparing companies within an industry, you can use the following methods:

1. Adjust for accounting differences. Different companies use different accounting policies, which affect ROE and require adjustments.
2. Consider industry characteristics. Industry competition, innovation capacity, and regulatory environments all impact ROE.
3. Analyze ROE drivers. ROE is determined by profit margins, asset turnover, and financial leverage; understanding these factors helps you compare companies more accurately.

Combining with Cash Flow

When screening for high-quality companies, you shouldn’t rely solely on ROE. Free Cash Flow (FCF) is equally important. ROE measures a company’s ability to generate profits from shareholders’ equity, while free cash flow reflects the cash available for reinvestment, dividends, or debt repayment after capital expenditures.

• A high ROE indicates strong profitability.
• Ample free cash flow suggests the company has the capacity for sustained growth and dividends.
• By combining these two metrics, you can identify companies that are both profitable and capable of creating sustained value for shareholders.

Comprehensive Analysis

When selecting stocks, you should combine multiple financial metrics for a comprehensive analysis. In addition to ROE and free cash flow, you can also consider Earnings Per Share (EPS), Price-to-Earnings (P/E) Ratio, Debt-to-Equity Ratio, Price-to-Book Ratio, Operating Margin, and Beta.

• Earnings Per Share (EPS) allows direct comparison of a company’s profitability.
• Price-to-Earnings (P/E) Ratio helps you assess whether a stock’s valuation is reasonable.
• Debt-to-Equity Ratio reflects a company’s financial risk.
• Price-to-Book Ratio compares a company’s market value to its book value.
• Operating Margin measures a company’s operational efficiency.
• Beta reflects stock volatility, helping you assess risk.

By combining these metrics, you can more comprehensively evaluate a company’s financial health and investment value. Scientific stock selection requires building a systematic analytical mindset and avoiding reliance on a single metric. Through multi-dimensional analysis, you can truly identify “golden” high-quality companies.

Case Studies

High ROE Companies

When analyzing the U.S. market, you can focus on companies that consistently maintain high ROE. For example, a U.S. tech company has maintained an ROE above 20% over the past five years. You can review its financial reports and find that its net income has grown steadily each year, with shareholders’ equity also increasing stably. The company’s management excels at using funds for R&D and market expansion, driving product innovation.

A high ROE typically indicates strong profitability and high management efficiency. You can use the following data to make judgments:

You can see that the company generates more profits with less shareholder capital each year. When selecting stocks, prioritizing such high-ROE companies can improve your investment success rate.

Low ROE Companies

When screening stocks, you’ll also encounter companies with low ROE. For example, a U.S. traditional retail company has had an ROE below 8% for the past three years. Reviewing its financial reports, you find that its net income growth is slow, while shareholders’ equity continues to increase. The company is at a competitive disadvantage in the market, and management has failed to utilize funds effectively.

A low ROE reflects insufficient profitability and low capital utilization efficiency. You can refer to the following data:

When investing, if you find a company’s ROE is consistently below the industry average, you should proceed with caution. Low-ROE companies often struggle to create sustained value for shareholders. You can combine other financial metrics to further assess whether the company is worth investing in.

Pitfalls of ROE-Based Stock Selection

Causes of Inflated ROE

When using ROE to screen companies, you may encounter situations where numbers are artificially “beautified.” Many companies use financial tactics to make ROE appear high, even though their actual profitability is weak. You need to be cautious of the following common causes of inflated ROE:

• Leverage Impact: Companies may boost ROE by taking on significant debt. For example, Marriott International’s high debt distorted its ROE. When you see a high ROE, you should examine the company’s debt levels.
• Accounting Manipulation: Management may adjust accounting earnings to inflate ROE, especially when executive bonuses are tied to ROE.
• Cash Reserves: Holding large cash reserves can lower ROE. For instance, Las Vegas Sands’ high cash reserves result in a lower ROE, which may lead you to misjudge its actual profitability.

To avoid blind stock picking, you shouldn’t focus solely on ROE figures; you must also analyze the company’s debt, cash reserves, and accounting policies.

Tip: Market analysts often use adjusted ROE to eliminate one-time events, tax effects, and non-operational factors. This provides a more accurate reflection of a company’s true profitability.

Limitations

When selecting stocks, relying solely on ROE can lead you into statistical traps. While ROE reflects a company’s efficiency in using shareholders’ funds, it has clear limitations:

• ROE relies on accounting earnings, which may be manipulated and may not accurately reflect a company’s profitability.
• ROE typically focuses on short-term performance, failing to capture a company’s long-term profitability.
• For capital-intensive or highly leveraged companies, ROE can be misleading.
• ROE lacks correlation with true profitability metrics like Return on Invested Capital (ROIC).
• Executives may manipulate ROE to boost personal bonuses, making the numbers unreliable.

To avoid blind stock picking, you should combine other financial metrics to assess a company’s value comprehensively. Many investors mistakenly believe that higher ROE is always better, but ROE is also influenced by accounting policies, off-balance-sheet items, and financing decisions.

When building a scientific stock selection system, you cannot rely solely on ROE. You must combine metrics like free cash flow and return on assets to truly identify “golden” companies and avoid the risks of blind stock picking.

When selecting stocks, ROE can help you quickly identify high-quality companies and steer clear of blind stock-picking risks. Combining ROE with ROA provides a more comprehensive assessment of a company’s capital utilization efficiency:

• ROE shows how much profit a company generates from shareholders’ equity.
• ROA tells you how effectively a company uses all its assets.
• Combining ROE and ROA helps you identify the sources of returns.

By continuously focusing on financial metrics and combining multiple methods, you can build a scientific stock selection system and improve the accuracy of your investment decisions.
