## What Is a Stock?

A **stock** (also called a share or equity) represents a small piece of ownership in a company. When you buy a stock of Reliance Industries, you become a part-owner of that company — however tiny your share might be.

Companies divide their total ownership into millions of small units called **shares**. When you buy shares on the stock market, you're buying these units from other investors.

## Why Do Companies Issue Stocks?

Companies need money to grow — to build factories, hire people, develop products, or expand to new markets. They have three main options:

1. **Use profits** — Slow, limited by current earnings
2. **Borrow (debt)** — Must be repaid with interest
3. **Issue shares (equity)** — Sell ownership stakes to investors

### The IPO Process

When a private company first sells shares to the public, it's called an **Initial Public Offering (IPO)**. After the IPO, shares trade on stock exchanges (BSE/NSE) in the **secondary market**, where investors buy and sell from each other.

## What Do You Get as a Shareholder?

### 1. Capital Appreciation
If the company grows and becomes more valuable, the stock price rises. You can sell your shares at a higher price than you paid — that's your profit (capital gain).

**Example:** If you bought 100 shares of a company at ₹200 each (₹20,000 invested) and the price rises to ₹300, your investment is now worth ₹30,000 — a ₹10,000 gain.

### 2. Dividends
Some companies share a portion of their profits with shareholders as **dividends**. This is passive income paid directly to your bank account.

**Example:** If a company declares a dividend of ₹10 per share and you hold 100 shares, you receive ₹1,000.

### 3. Voting Rights
Shareholders can vote on important company decisions at the Annual General Meeting (AGM), such as appointing directors or approving mergers.

## Types of Stocks

### By Market Capitalisation

| Type | Market Cap | Examples |
|------|-----------|---------|
| Large-cap | Above ₹20,000 crore | Reliance, TCS, HDFC Bank |
| Mid-cap | ₹5,000 - ₹20,000 crore | Persistent Systems, Trent |
| Small-cap | Below ₹5,000 crore | Thousands of smaller companies |

### By Investment Style

- **Growth stocks** — Companies growing revenues and profits rapidly (often reinvest profits instead of paying dividends)
- **Value stocks** — Companies trading below their intrinsic value (potential bargains)
- **Dividend stocks** — Companies that regularly pay attractive dividends (e.g., Coal India, ITC)

## Stock Price: What Moves It?

The stock price is determined by **supply and demand** — how many people want to buy vs sell at any given moment.

### Factors That Affect Stock Prices

| Factor | Effect |
|--------|--------|
| Company earnings | Strong results → price rises |
| Industry trends | Growing sector → all stocks in sector may rise |
| Economic conditions | GDP growth, inflation, interest rates |
| Market sentiment | Fear → selling; optimism → buying |
| FII/DII flows | Large institutional buying/selling |
| News and events | Regulatory changes, management changes |

## Key Terms Every Stock Investor Should Know

- **Market Cap** = Stock Price × Total Number of Shares
- **EPS (Earnings Per Share)** = Net Profit ÷ Number of Shares
- **P/E Ratio** = Stock Price ÷ EPS (how expensive the stock is relative to earnings)
- **Book Value** = Total Assets minus Total Liabilities, divided by shares
- **Face Value** = Nominal value of a share (usually ₹1, ₹2, or ₹10 in India)
- **52-Week High/Low** = Highest and lowest price in the past year

## How to Buy Your First Stock

1. Open a **Demat and trading account** with a broker (Zerodha, Groww, Angel One, etc.)
2. Transfer funds from your bank account
3. Search for the company by name or ticker symbol
4. Place a **buy order** (market order or limit order)
5. Shares are credited to your Demat account in T+1 (next business day)

## Common Mistakes to Avoid

- **Buying based on tips** — Always do your own research
- **Putting all money in one stock** — Diversify across at least 10-15 stocks or use mutual funds
- **Panic selling** — Short-term volatility is normal; focus on long-term fundamentals
- **Ignoring fundamentals** — A low price doesn't mean a good stock; look at earnings, debt, and management quality
- **Trading too frequently** — Brokerage, taxes, and STT eat into returns
