Key Metrics for Indian Stocks: A Comprehensive Guide

When you look at a company's stock, the price alone tells you very little. To judge whether a share is expensive or cheap relative to the business behind it, investors use financial metrics, standardised ratios that make companies comparable. This guide explains the most important metrics for Indian stocks, what each measures, and how to read them with the caution they deserve.

Earnings Per Share and the P/E Ratio

Earnings per share (EPS) is a company's net profit divided by its number of shares. If a company earns Rs 500 crore and has 50 crore shares, its EPS is Rs 10. EPS tells you how much profit each share represents.

The price-to-earnings (P/E) ratio divides the share price by EPS. A share priced at Rs 200 with an EPS of Rs 10 has a P/E of 20, meaning investors are paying Rs 20 for every Rs 1 of annual profit. A high P/E signals that the market expects strong future growth; a low P/E may indicate low expectations or an out-of-favour company. Crucially, "high" and "low" only make sense compared to the company's own history and to peers in the same industry, since a fast-growing software firm and a stable utility naturally command very different P/E levels.

One important caution is that EPS, and therefore P/E, can be distorted by one-off events. A company might report an unusually high profit because it sold a factory or received an insurance payout, temporarily inflating EPS and making the P/E look deceptively low. The reverse happens when a single bad year depresses earnings and makes the ratio look alarmingly high. This is why investors look at earnings over several years rather than a single quarter, and why a metric should always prompt the question "what is driving this number?" rather than being accepted at face value.

Price-to-Book and What It Reveals

Book value is the company's assets minus its liabilities, essentially its net worth on the balance sheet. The price-to-book (P/B) ratio compares the share price to book value per share. A P/B of 3 means the market values the company at three times its accounting net worth.

P/B is especially useful for asset-heavy businesses such as banks and manufacturers, where the balance sheet closely reflects the firm's value. It is less meaningful for asset-light businesses whose value lies in brands, software, or people rather than physical assets. As with P/E, compare P/B within an industry, not across unrelated sectors.

Return on Equity: Measuring Efficiency

Return on equity (ROE) measures how much profit a company generates from shareholders' money. It is net profit divided by shareholders' equity, expressed as a percentage. If a company earns Rs 100 crore on Rs 500 crore of equity, its ROE is 20%.

A consistently high ROE suggests management uses capital efficiently, which is a hallmark of quality businesses. However, ROE can be inflated by heavy borrowing, since debt reduces the equity base. That is why ROE should always be read alongside the company's debt levels, a high ROE built on dangerous leverage is far less impressive than the same figure achieved with little debt.

Debt-to-Equity and Financial Health

The debt-to-equity ratio compares a company's total borrowings to its shareholders' equity. A ratio of 0.5 means the company has Rs 0.50 of debt for every Rs 1 of equity; a ratio of 2 means it has twice as much debt as equity.

High debt magnifies both profits in good times and losses in bad times, and it creates fixed interest obligations that must be paid regardless of business conditions. During downturns or rising interest rates, heavily indebted companies are far more vulnerable. Acceptable levels vary by industry, capital-intensive sectors naturally carry more debt, so again, compare within the sector rather than applying one universal threshold.

Alongside the level of debt, it is worth checking whether the company comfortably earns enough to service it. A business whose operating profit covers its interest obligations many times over is far safer than one where interest payments swallow most of the earnings, even if their headline debt-to-equity ratios look similar. Cash flow tells this story better than accounting profit alone, because a company can report profit on paper while struggling to generate the actual cash needed to pay lenders. Reading the balance sheet and cash flow together gives a far more honest picture of financial resilience.

Dividend Yield and Cash Returns

Dividend yield is the annual dividend per share divided by the share price. A Rs 4 dividend on a Rs 100 share is a 4% yield. It shows how much cash income you receive relative to price, independent of price appreciation.

A steady dividend can signal a mature, cash-generative business, but a very high yield sometimes reflects a falling share price rather than generosity, so it warrants a closer look. Also check the payout ratio, the share of profit paid as dividends, since a company paying out more than it earns cannot sustain that indefinitely. Metrics like yield are clues to investigate, not verdicts on their own.

Using Metrics Wisely: A Checklist

No single metric tells the whole story, and every ratio can be distorted by one-off events, accounting choices, or industry quirks. The professional habit is to read several metrics together and in context. A practical checklist: compare each ratio to the company's own history and to industry peers; check whether earnings are consistent or lumpy; confirm that a high ROE is not merely the product of high debt; and read the numbers alongside the qualitative story of what the business actually does.

Metrics are tools for asking better questions, not crystal balls. A cheap-looking stock may be cheap for good reason, and an expensive one may deserve its premium. Used carefully, these ratios help you avoid overpaying and spot financial fragility, but they never replace understanding the underlying business.
