Key Terminology & Concepts in the Stock Market: A Beginner’s Guide
Investing in the stock market can feel overwhelming at first. But once you get familiar with the basic terminology and concepts, everything starts to make a lot more sense. Whether you're a newbie or brushing up on your knowledge, this guide will help you navigate the essentials of the stock market like a pro.
Stock vs. Share
Stock represents ownership in a company.
Share is the specific unit of that ownership.
Example: If you buy shares of Reliance Industries, you own a piece of that company. You don’t trade "stock" directly—you trade shares of stock on stock exchanges.
Stock Exchanges
These are platforms where shares are bought and sold. In India, the two major exchanges are:
BSE (Bombay Stock Exchange)
NSE (National Stock Exchange)
Sensex & Nifty
Sensex: The benchmark index of BSE, tracking 30 top companies.
Nifty 50: The benchmark index of NSE, tracking 50 major companies.
These indexes reflect the overall market performance.
IPO (Initial Public Offering)
When a company sells its shares to the public for the first time. It’s a way to raise capital and allows investors to become early shareholders.
Market Capitalization
The total value of a company’s outstanding shares:
Large-Cap: Big, stable companies (e.g., HDFC Bank, TCS)
Mid-Cap: Medium-sized firms with growth potential
Small-Cap: Smaller, high-risk-high-reward companies
Bull vs. Bear Market
Bull Market: Rising stock prices and investor optimism
Bear Market: Falling prices and widespread pessimism
Bid Price vs. Ask Price
Bid Price: Highest price a buyer is willing to pay
Ask Price: Lowest price a seller will accept
The difference between them is the spread.
Order Types
Market Order: Buy/sell at the current market price
Limit Order: Set a specific price for buy/sell

EPS (Earnings Per Share)
A key indicator of profitability:
EPS = Net Income / Total Outstanding Shares
Higher EPS usually indicates better performance.
P/E Ratio (Price-to-Earnings Ratio)
Shows if a stock is overvalued or undervalued:
P/E = Stock Price / EPS
High P/E: May be overvalued
Low P/E: Could be undervalued
Blue-Chip Stocks
Top-tier, stable companies with a solid track record (e.g., Reliance, TCS). Ideal for long-term investors.
Portfolio Diversification
Investing across different sectors (IT, pharma, FMCG, etc.) to minimize risk. A diverse portfolio can weather market volatility better.

Intraday: Buy and sell on the same day
Delivery: Buy and hold for a longer duration
Futures & Options (F&O)
