Stock Exchanges
A stock exchange is the marketplace where buyers and sellers meet to trade shares. Think of it as a giant digital bazaar for stocks.
You don't directly visit an exchange. You place orders through a broker, and the exchange matches your order with another trader.
What is a Stock Exchange?
A stock exchange is an organized platform that:
- Facilitates buying and selling of shares
- Ensures fair and transparent pricing
- Maintains records of all transactions
- Enforces rules to protect investors
Without exchanges, there would be no standard way to buy or sell shares. You'd have to find individual sellers yourself – chaotic and risky.
Major Indian Stock Exchanges
India has two primary stock exchanges:
NSE – National Stock Exchange
- Founded: 1992
- Index: Nifty 50
- Features: Largest by trading volume, fully electronic from day one
BSE – Bombay Stock Exchange
- Founded: 1875
- Index: Sensex
- Features: Asia's oldest exchange, located in Mumbai
Most stocks are listed on both NSE and BSE. You can buy on one exchange and sell on the other, though prices may differ slightly.
Market Indices: Nifty and Sensex
Indices track the overall market performance by monitoring a selection of top stocks.
| Index | Stocks Tracked | Represents |
|---|---|---|
| Nifty 50 | 50 companies | NSE's top performers |
| Sensex | 30 companies | BSE's top performers |
If the Nifty goes up by 2%, it means the average price of those 50 stocks increased by 2%.
Indices don't include all stocks – just the biggest and most actively traded ones. They're a snapshot, not the complete picture.
How Trading Works
Trading happens in real-time during market hours:
| Session | Time |
|---|---|
| Pre-Open | 9:00 AM – 9:15 AM |
| Normal Trading | 9:15 AM – 3:30 PM |
| Post-Close | 3:30 PM – 4:00 PM |
During these hours:
- You place a buy or sell order through your broker
- The order goes to the exchange
- The exchange matches it with a corresponding order
- The trade is executed and recorded
T+1 Settlement
When you buy a stock today, you don't own it immediately. Settlement happens the next trading day (T+1).
- T = Trade day (when you bought)
- +1 = One business day later (when shares appear in your Demat)
This means funds are debited quickly, but shares take a day to reflect in your account.
Why This Matters
Understanding exchanges helps you:
- Know where your trades happen
- Understand market hours for planning
- Interpret index movements in the news
- Appreciate the infrastructure protecting your investments
Key Takeaways
- NSE and BSE are India's two main stock exchanges
- Nifty 50 and Sensex track top stocks as market indicators
- Trading hours are 9:15 AM to 3:30 PM on weekdays
- Settlement takes T+1 (next business day)
