Chapter 15
15Stock Market Basics
The stock market chapter gives the minimum language needed before buying individual shares. It begins with ownership, then company size, revenue, profit, debt, valuation, dividends, and PE ratio.
Share
Example: buying one share of an Indian listed company means owning a tiny claim on that business. The share price moves daily, but the underlying claim is on future profits and assets.
A share is a unit of ownership in a company listed on Indian exchanges or otherwise issued under Indian securities law.
It gives claim on residual value after all obligations are met. Its price changes because expectations about future cash flows change.
Risk capital only.
- Buy shares only with risk capital.
- Understand the business before buying individual stocks.
- Do not confuse price movement with business quality.
Company ownership
Example: shareholders of a bank or consumer company are owners after lenders and employees are paid. Ownership can create wealth only if the company creates value over time.
Owning equity means participating in business outcomes.
If the company grows profitably, owners may benefit. If it fails, owners can lose. Equity holders are last in the claim hierarchy, so return potential is paired with risk.
Think like an owner.
- Think like an owner, not a ticket holder.
- Study earnings, debt, management, and industry.
- Diversify ownership.
Market capitalization
Example: a company with 100 crore shares at INR 500 has a market capitalization of INR 50,000 crore. Market cap tells what the market currently values the equity at, not what the company earned last year.
Market capitalization equals share price multiplied by number of shares. It is the market's current INR value for the company.
Large, mid, and small caps differ in maturity, liquidity, growth potential, and risk.
Size is context.
- Use market cap to understand size and risk.
- Do not assume small means cheap or large means safe.
- Compare companies within relevant sectors.
Revenue
Example: a retailer may report rising sales because it opened more stores, but revenue alone does not show whether the growth is profitable. It is the top line, not the final outcome.
Revenue is money earned from selling goods or services before expenses. It is the top line.
Revenue growth matters only if it can eventually become cash profit.
Sales are not enough.
- Check whether revenue is recurring, cyclical, or one-time.
- Compare revenue growth with margin and cash flow.
- Avoid valuing a company on sales alone.
Profit
Example: a software company with high margins and low debt may convert revenue into profit better than a capital-heavy business. Profit quality matters because owners are paid from residual earnings.
Profit is what remains after costs, interest, depreciation, and tax.
Profit is an accounting measure of business surplus. Its quality depends on cash conversion, sustainability, and capital required to produce it.
Check profit quality.
- Study profit along with operating cash flow.
- Prefer durable profit over temporary spikes.
- Watch margin trends.
Debt
Example: a company borrowing heavily for expansion may do well if cash flows arrive, but suffer if demand slows or rates rise. Debt magnifies both success and distress.
Company debt is borrowed money that must be serviced through interest and principal repayment.
Leverage magnifies outcomes
Debt can improve return when business is strong and destroy equity when cash flow weakens. Debt is a fixed obligation; equity return is variable.
Respect leverage
- Check debt-to-equity, interest coverage, and cash flow.
- Be cautious with high debt in cyclical businesses.
- Compare leverage with industry norms.
Valuation
Example: a good Indian company bought at an extreme price can still produce poor investor returns. Valuation connects business quality with the price paid for that quality.
Valuation links INR price to business fundamentals.
Discounted cash flow principle
Value is related to future cash flows adjusted for risk and time. A good Indian company can be a poor investment if bought at an extreme price.
Price matters
- Compare price with earnings, cash flow, book value, and growth.
- Avoid buying only because the story is attractive.
- Demand margin of safety when uncertainty is high.
Dividend
Example: mature companies may distribute part of profit as dividends, while growing companies may reinvest. For an Indian resident, dividends are cash flow but also taxable income.
Dividend is a distribution of profit to shareholders.
It is one form of owner return. A high dividend is useful only if the business can sustain it without damaging growth or balance sheet.
Do not chase yield alone.
- Check dividend payout and cash generation.
- Do not chase dividend yield without business quality.
- Remember dividends may be taxed.
PE ratio
Example: a PE of 40 means investors are paying forty rupees for one rupee of annual earnings. The ratio is meaningful only after considering growth, stability, cyclicality, and accounting quality.
Price-to-earnings ratio equals market price per share divided by earnings per share.
PE tells how much investors pay for one unit of earnings. It is meaningful only with growth, quality, cyclicality, and accounting context.
Use PE with context.
- Compare PE within similar businesses.
- Low PE can signal value or trouble.
- High PE requires strong and durable growth justification.
