Basic Stock Market Terminologies: When you step into the stock market, you’ll often hear new terms like share, equity, IPO, Sensex, Nifty, SEBI, market cap etc. For beginners, these words may sound confusing, but don’t worry — we’ll explain them step by step in simple language.
Stock Market Terminologies Share, Stock & Equity
- Share: A single unit of ownership in a company.
Example: If a company has 1,000 shares and you own 10, then you own 1% of the company. - Stock: A general term used for the collection of shares.
Example: If you own multiple shares of Infosys, HDFC, and Reliance, you can say “I have stocks in these companies.” - Equity: Another word for ownership in a company. When you buy shares, you are buying equity.
In short: Share = Unit, Stock = Collection, Equity = Ownership.
IPO (Initial Public Offering)
When a private company wants to raise money from the public, it issues shares for the first time through an IPO.
- Example: Zomato’s IPO (2021), LIC IPO (2022).
- Investors can apply in IPOs and become shareholders when the company lists on NSE/BSE.
Stock Market Terminologies NSE, BSE & SEBI
- NSE (National Stock Exchange): India’s largest stock exchange (famous index = Nifty 50).
- BSE (Bombay Stock Exchange): Asia’s oldest stock exchange (famous index = Sensex).
- SEBI (Securities and Exchange Board of India): The regulator of stock markets in India. It ensures fairness, transparency, and investor protection.
You can think of NSE & BSE as marketplaces, while SEBI is the watchdog.
Market Capitalization (Market Cap)
Market Cap means the total value of a company in the stock market.
Formula: Market Cap = Share Price × Total Number of Shares
Based on size, companies are classified into:
- Large Cap – Big companies, safe and stable (e.g., Reliance, HDFC Bank).
- Mid Cap – Medium-sized companies with growth potential (e.g., Tata Elxsi, JSW Energy).
- Small Cap – Small companies, high risk but high return potential.
Stock Market Index (Sensex & Nifty)
- Index is like a report card of the stock market.
- It measures the performance of selected top companies.
- Sensex – Index of BSE, includes 30 top companies.
- Nifty 50 – Index of NSE, includes 50 top companies.
If Nifty/Sensex goes up, it means overall market sentiment is positive. If they fall, the market is weak.
