Introduction
When you start analyzing a company’s performance, it’s easy to feel lost in numbers and jargon. The good news? You don’t need to be a finance expert to evaluate a stock effectively. By learning a few key ratios for stock analysis, you can easily judge profitability, valuation, and financial health. These important financial ratios for investors form the foundation of fundamental analysis ratios used across global markets — including India. Let’s explore seven essential stock market ratios that can help you make smarter investment decisions.
1. Price-to-Earnings (P/E) Ratio
What it is: The most popular among ratios for value investing, P/E shows how much investors are willing to pay for ₹1 of a company’s earnings.
Formula:
P/E Ratio = Market Price per Share ÷ Earnings per Share (EPS)
Interpretation:
- A high P/E may indicate growth expectations or overvaluation.
- A low P/E might mean undervaluation or company challenges.
PE ratio importance:
The P/E helps investors determine if a stock is cheap or expensive compared to peers. It’s one of the first ratios before buying stocks you should review in any stock investing checklist ratios.
2. Earnings Per Share (EPS)
What it is: The earnings per share ratio measures how much profit is available for each outstanding share.
Formula:
EPS = (Net Profit – Preferred Dividends) ÷ Total Outstanding Shares
Understanding EPS in stocks:
A higher and steadily rising EPS indicates robust profitability and healthy growth potential.
EPS trends help identify investment grade ratio stocks that generate sustainable earnings.
3. Price-to-Book (P/B) Ratio
What it is: The price to book ratio explained compares a stock’s market price with its net asset value per share.
Formula:
P/B = Market Price per Share ÷ Book Value per Share
Interpretation:
- A P/B below 1 may show undervaluation.
- A P/B above 1 implies the market values the company higher than its book assets.
Why it matters:
Useful for capital-heavy sectors like banking, manufacturing, and finance, it’s a trusted metric in ratio analysis for Indian stocks.
4. Debt-to-Equity (D/E) Ratio
What it is: The debt to equity ratio evaluates how much a company depends on borrowed money.
Formula:
D/E = Total Liabilities ÷ Shareholders’ Equity
Importance of debt to equity ratio for safe investing:
- A high D/E signals reliance on debt — risky in volatile markets.
- A low ratio implies financial stability.
Debt equity ratio calculation is crucial in risk evaluation, especially for industries with heavy capital requirements.
5. Return on Equity (ROE)
What it is: The return on equity ratio measures how efficiently management uses shareholders’ capital to generate profits.
Formula:
ROE = Net Income ÷ Shareholders’ Equity
How to use ROE for investment:
- A consistent ROE above 15% shows efficient capital usage.
- Declining ROE might indicate operational inefficiencies.
Why it matters:
In stock selection using ratios, ROE is a key profitability measure for identifying best ratios to pick stocks in India.
6. Dividend Yield
What it is: The dividend yield ratio evaluates how much a stock pays in annual dividends relative to its price.
Formula:
Dividend Yield = (Annual Dividend per Share ÷ Market Price per Share) × 100
Why it’s important:
It’s invaluable for conservative investors seeking income from equities. Dividend yields complement long-term wealth creation strategies and attract those prioritizing cash returns over price gains.
Example:
Power Grid, ITC, and Coal India are great examples of Indian companies with high dividend yields.
7. Price-to-Sales (P/S) Ratio
What it is: The P/S compares the stock price to revenue, useful for startups and early-growth-stage firms.
Formula:
P/S = Market Capitalisation ÷ Total Revenue
Why it’s relevant:
It’s especially meaningful when companies aren’t yet profitable but generate strong sales turnover.
Interpreting P/S with profit margin ratio provides insights into operational efficiency.
Why Do These Ratios Matter?
When combined, these financial ratios to evaluate stocks paint a full picture of valuation, profitability, and leverage. They help you compare competitors, assess investment quality, and decide what fits your financial goals.
Which financial ratios should you check before buying Indian stocks?
Start with P/E, ROE, and D/E — these three define valuation, profitability, and risk in one snapshot.
Additional Ratios Investors Should Watch

- Current Ratio stocks: Measures liquidity (Current Assets ÷ Current Liabilities).
- Profit Margin Ratio: Shows net profit as a percentage of sales.
How does the current ratio affect stock analysis?
A ratio above 1.5 generally suggests healthy liquidity, though benchmarks differ by industry.
