Starting your journey in the stock market can feel overwhelming, but understanding the fundamentals is the first step to becoming a confident investor. This comprehensive guide breaks down everything you need to know.

What is the Stock Market?

The stock market is a marketplace where investors buy and sell shares of publicly traded companies. When you buy a stock, you’re purchasing a small piece of ownership in that company.

Key Market Concepts

Stock Exchanges: The primary venues where stocks are traded include:

• NYSE (New York Stock Exchange): The world’s largest stock exchange
• NASDAQ: Known for technology stocks
• Other Global Exchanges: LSE, TSE, and regional markets

Market Participants:

• Individual investors (retail traders)
• Institutional investors (hedge funds, mutual funds)
• Market makers who provide liquidity
• Broker-dealers who facilitate trades

How the Stock Market Works

Supply and Demand

Stock prices are determined by supply and demand. When more people want to buy a stock than sell it, the price goes up. When more people want to sell than buy, the price goes down.

Market Orders vs. Limit Orders

Market Order: Buys or sells immediately at the current market price

• Guarantees execution
• Price may vary slightly from what you see

Limit Order: Buys or sells only at your specified price or better

• Guarantees price
• May not execute if price isn’t reached

Trading Hours

Regular trading hours: 9:30 AM - 4:00 PM EST

• Pre-market: 4:00 AM - 9:30 AM EST
• After-hours: 4:00 PM - 8:00 PM EST

Types of Stocks

Common Stock vs. Preferred Stock

Common Stock:

• Voting rights in company decisions
• Potential for dividends
• Capital appreciation opportunity
• Higher risk, higher potential reward

Preferred Stock:

• Fixed dividend payments
• Priority over common stock in bankruptcy
• Limited voting rights
• Less price volatility

Growth Stocks vs. Value Stocks

Growth Stocks: Companies expected to grow faster than the market average

• High P/E ratios
• Reinvest profits rather than pay dividends
• Examples: Technology companies, emerging sectors

Value Stocks: Undervalued companies trading below their intrinsic value

• Lower P/E ratios
• Often pay dividends
• Examples: Established companies in mature industries

Key Stock Market Metrics

Price-to-Earnings Ratio (P/E)

Formula: Stock Price ÷ Earnings Per Share

A P/E ratio of 15 means investors are willing to pay $15 for every $1 of earnings.

• High P/E: Growth expectations or overvaluation
• Low P/E: Value opportunity or struggling company

Market Capitalization

Total value of all company shares: Share Price × Total Shares Outstanding

Categories:

• Large-cap: $10 billion+ (stable, established)
• Mid-cap: $2-10 billion (growth potential, moderate risk)
• Small-cap: $300 million-$2 billion (high growth, higher risk)

Dividend Yield

Annual dividend per share ÷ Stock price

A 3% dividend yield means you earn $3 annually for every $100 invested.

Beta

Measures volatility compared to the overall market:

• Beta = 1: Moves with the market
• Beta > 1: More volatile than market
• Beta < 1: Less volatile than market
