What Is ROE? How to Use Return on Equity for Stock Selection

Return on Equity (ROE) is widely regarded as the single most important metric for identifying high-quality businesses. Warren Buffett considers consistently high ROE as his primary filter for investment candidates. In this comprehensive guide, we will explore how to use ROE effectively for stock selection in the Indian market — going beyond the basic formula to understand what drives ROE, how to spot artificially inflated figures, and how to combine ROE with other metrics for better investment decisions.

ROE Formula Refresher

ROE = Net Income ÷ Shareholders’ Equity × 100. This ratio measures the return generated on the capital that shareholders have invested in the company. A ROE of 20% means the company generates ₹20 of profit for every ₹100 of shareholders’ equity. For a deeper understanding of the basics, refer to our ROE glossary page.

The ROE Quality Framework

Not all high ROE is created equal. The DuPont decomposition reveals three drivers: Net Profit Margin × Asset Turnover × Financial Leverage. Understanding which driver is dominant tells you the quality of the ROE.

Margin-Driven ROE (Best Quality): Companies like TCS and Infosys achieve high ROE primarily through high profit margins. They earn 20-25% net margins because their services command premium pricing and have low variable costs. This type of ROE is the most sustainable because it comes from genuine competitive advantages — brand strength, intellectual property, or network effects.

Turnover-Driven ROE (Good Quality): Companies like DMart and Titan achieve high ROE through efficient asset utilization — they generate high revenue relative to their asset base. DMart’s thin margins (around 8%) are compensated by extremely high inventory turnover. This model works well but requires operational excellence to maintain.

Leverage-Driven ROE (Caution): When ROE is high primarily because of financial leverage (high debt), the quality is lowest. Check the debt-to-equity ratio — if it is above 1.5 and driving the high ROE, the company may be taking excessive financial risk. During downturns, leverage-driven ROE can collapse rapidly as interest costs remain fixed while profits decline.

ROE Screening Criteria for Indian Stocks

Here is a practical screening framework that has historically identified quality Indian businesses. Look for ROE consistently above 15% for at least 5 consecutive years — consistency matters more than peak levels. ROE should be driven by margins or turnover, not leverage — debt-to-equity below 1 for non-financial companies. EPS growth should broadly track ROE — if ROE is 20% but EPS grows only 5%, investigate the disconnect. And PE ratio should be reasonable relative to ROE — a simple rule is PEG (PE ÷ EPS Growth) below 1.5.

ROE Across Indian Sectors

Each sector has its own ROE characteristics. IT Services (TCS, Infosys, HCL Tech) consistently deliver 25-35% ROE thanks to asset-light models and high margins. FMCG (HUL, Nestle, Dabur) show 25-50%+ ROE driven by brand power and minimal capital needs. Private Banks (HDFC Bank, ICICI, Kotak) deliver 14-17% ROE — which is excellent given banking’s inherently leveraged model. Pharma shows a wide range (10-25%) depending on whether the company has a strong branded portfolio. And Capital Goods/Infrastructure typically show 10-15% ROE due to high capital requirements.

ROE and Reinvestment: The Compounding Machine

The real magic happens when a company earns high ROE AND reinvests most of its profits back into the business at similar returns. If a company earns 25% ROE and retains 75% of profits (paying 25% as dividends), its book value grows at approximately 18.75% annually (25% × 75%). Over time, this growing book value drives stock price appreciation — this is the essence of compounding wealth through quality stocks.

Companies like Asian Paints, Pidilite, and Bajaj Finance have been such compounding machines — maintaining high ROE while reinvesting aggressively for growth, delivering 20-25% annual stock price appreciation over decades.

Common ROE Pitfalls to Avoid

Beware of negative equity inflating ROE to meaningless levels. If a company has accumulated losses exceeding its paid-up capital, equity turns negative and ROE becomes meaningless. Also, share buybacks reduce equity (making ROE look better) even if profits haven’t grown — always check if net income is actually growing. Finally, one-time exceptional items can temporarily spike net income and inflate ROE — use normalized or adjusted ROE for accurate assessment.

Frequently Asked Questions

What ROE should I look for in Indian stocks?

For non-financial companies, look for ROE consistently above 15% for at least 5 years. Above 20% indicates excellent quality. For banks, 14%+ is strong given regulatory constraints. Always compare within the same sector and verify the ROE is not artificially inflated by high leverage or one-time items. The consistency of ROE over multiple years matters more than any single year’s number.

Can ROE decline even when profit grows?

Yes. If a company raises equity capital (like an IPO or rights issue), shareholders’ equity increases. If the new capital doesn’t generate proportional profits immediately, ROE declines even though absolute profit may grow. This is common in capital-raising phases. What matters is whether ROE recovers as the new capital is deployed productively. Check if the intrinsic value is being created despite temporary ROE dips.

How do I find ROE data for Indian companies?

Free sources include Screener.in (shows 10+ years of ROE trends), Trendlyne, Tickertape, and MoneyControl. Most broker platforms (Zerodha, Groww) also show key ratios including ROE. For the most accurate figures, calculate ROE yourself from the annual report — take PAT (Profit After Tax) from the P&L and divide by average shareholders’ equity from the balance sheet.
