3. The marketplace – NSE and BSE
If shares are the product, the stock exchange is the marketplace. Just like a vegetable mandi brings farmers and buyers together, a stock exchange brings sellers and buyers of shares together.
India has two main stock exchanges:
- BSE – formerly known as the Bombay Stock Exchange.
- NSE – the National Stock Exchange of India.
Most large companies are listed on both. When you place an order on your app, you can usually choose NSE or BSE. The price is almost the same on both.
In the 1850s, a small group of share brokers in Bombay used to meet under a banyan tree near the Town Hall. They traded shares of cotton mills and banks, shouting prices and shaking hands on deals.
As the group grew, they kept shifting place – first to another banyan tree, then to Dalal Street. In 1875 they formed an association. That association became the Bombay Stock Exchange, the oldest stock exchange in Asia. That is why, even today, people say "Dalal Street" when they mean the Indian stock market.
3.1 What does a stock exchange actually do?
- Lists companies. A company must meet strict rules to get listed.
- Runs the order book. It collects buy and sell orders from across India and matches them – fairly and in order of price and time.
- Shows prices to everyone. Every trade price is visible to all. Nobody gets a secret, better price.
- Watches for cheating. Exchanges monitor trades for price manipulation and make rules for companies and brokers.
3.2 Why NSE changed everything
Till the early 1990s, trading happened on a crowded "trading floor" at BSE. Brokers shouted orders. Prices were not always fair, and small investors outside Mumbai were at a disadvantage.
NSE started in 1994 with something new for India – fully electronic, screen-based trading. A broker in Nashik or Guwahati could now trade at the same price, at the same moment, as a broker in Mumbai. BSE also moved to electronic trading soon after.
Today, everything is on screens and apps. Orders get matched in a fraction of a second.
3.3 Exchanges are not the only players
The exchange is just one part of the system. Here is the full team you will meet in the next few chapters:
| Who | Simple role |
|---|---|
| SEBI | The referee. Makes rules and punishes cheaters. |
| Stock exchange (NSE, BSE) | The marketplace where orders are matched. |
| Broker | Your entry gate to the exchange. Your app. |
| Clearing corporation | Makes sure the buyer gets shares and the seller gets money. |
| Depository (NSDL, CDSL) | The locker that holds your shares in electronic form. |
NSE also runs the most popular index in India – the Nifty 50. BSE runs the Sensex. We will learn what an index is in Chapter 9.
Ek baat yaad rakho: the exchange does not decide prices. Buyers and sellers do. The exchange only makes sure the matching is fair. When someone says "the market fell", it simply means more people wanted to sell than buy.
The exchange is the marketplace and the referee of matching. Prices come from buyers and sellers.
BSE is older. NSE’s big change was nationwide electronic trading, which made prices fair and equal for everyone.
- A stock exchange is a marketplace for shares. India’s main exchanges are NSE and BSE.
- BSE (1875) is Asia’s oldest exchange. NSE (1994) brought screen-based trading to all of India.
- Exchanges list companies, match orders, show prices to all and watch for cheating.
- Prices are set by buyers and sellers, not by the exchange.
- Ek line mein: NSE aur BSE sirf bazaar hain – price buyers aur sellers milke decide karte hain, exchange nahi.
