What is Fundamental Analysis?
Imagine you're buying a business, not just a stock ticker. Fundamental analysis is exactly that — studying a company's financial health, earnings, and growth to decide if its stock price is fair, cheap, or expensive.
While technical analysis looks at charts and patterns, fundamental analysis looks at the business behind the stock. Think of it as checking the engine before buying a car.
The Key Numbers You Need to Know
1. EPS (Earnings Per Share)
EPS tells you how much profit a company makes for each share you own. If a company earns ₹100 crore and has 10 crore shares, the EPS is ₹10.
Higher EPS = more profitable. But always compare EPS with companies in the same industry — comparing Infosys with Tata Steel doesn't make sense.
2. P/E Ratio (Price-to-Earnings)
The P/E ratio is the most popular valuation metric. It tells you how much investors are willing to pay for ₹1 of earnings.
Formula: P/E = Stock Price ÷ EPS
A P/E of 20 means investors pay ₹20 for every ₹1 the company earns. A low P/E might mean the stock is undervalued (or struggling). A high P/E could mean it's overvalued (or growing fast).
Pro tip: Nifty 50's average P/E hovers around 20-22. Stocks trading well above this need strong growth to justify the premium.
3. P/B Ratio (Price-to-Book)
P/B compares the stock price with the company's book value (assets minus liabilities, per share). A P/B of 1 means you're paying exactly what the company's assets are worth on paper.
P/B below 1? The stock might be a bargain — or the company might be in trouble. Banks and NBFCs are best evaluated using P/B since their main business is lending money.
4. ROE (Return on Equity)
ROE measures how efficiently a company uses shareholders' money to generate profits. An ROE of 20% means the company generates ₹20 of profit for every ₹100 of equity.
Consistently high ROE (above 15%) is a sign of a quality business. Think Asian Paints, TCS, or HDFC Bank.
5. Debt-to-Equity Ratio (D/E)
This tells you how much debt the company has compared to its own money (equity). A D/E of 0.5 means for every ₹100 of equity, the company has ₹50 of debt.
Low D/E (below 1) is generally safer. High D/E isn't always bad — infra and real estate companies naturally carry more debt — but excessive debt during rising interest rates can crush profits.
6. Revenue & Profit Growth
A company can have great ratios today but if revenue is shrinking, those ratios will deteriorate. Look for consistent revenue and profit growth over 3-5 years, not just one great quarter.
One quarter doesn't make a trend. Always check at least 3 years of results before drawing conclusions.
Putting It All Together: A Quick Checklist
- EPS growing year over year?
- P/E reasonable compared to peers?
- ROE consistently above 15%?
- Debt-to-Equity under control?
- Revenue and profit growing for 3+ years?
- Business you understand?
If a stock checks most of these boxes, it's worth deeper research. If it fails multiple checks, move on — there are thousands of stocks out there.
Common Mistakes Beginners Make
Buying only because P/E is low.
A low P/E can be a value trap — the stock might be cheap because the business is dying. Always check WHY the P/E is low.
Ignoring debt.
Companies like Vodafone Idea or Yes Bank looked great on revenue — until their debt became unmanageable. Always check D/E.
Chasing one metric.
No single number tells the full story. Use EPS, P/E, ROE, and D/E together to build a complete picture.
