What Are NSE and BSE?

A stock exchange is a regulated marketplace that provides the systems and rules for buying and selling

securities.

Modern exchanges are electronic. They receive orders from registered brokers, arrange them by price and

time, and match compatible orders.

The National Stock Exchange of India, commonly called NSE, and BSE Limited, commonly called BSE, are

India's major stock exchanges.

Both provide markets for shares and other permitted securities. They operate under Indian securities law

and SEBI oversight.

 Admits eligible companies for listing

 Provides an electronic order-matching system

 Publishes prices and market data

 Sets trading procedures and surveillance controls

 Coordinates clearing and settlement through the market infrastructure

 Monitors unusual activity and compliance

 Provides mechanisms for corporate announcements and disclosures

Listing means that a company's securities have been admitted to trading on an exchange after meeting

applicable requirements.

Trading means investors buying and selling those listed securities in the secondary market.

A company can be listed on one exchange or on both, subject to rules and approvals.

Yes. Many Indian companies are listed on both exchanges.

The economic ownership represented by the share is the same, but the exchange order books are separate.

Prices are usually very close because traders respond to differences, but small variations can exist due to

liquidity, timing and order flow.

On NSE, companies are commonly identified by trading symbols. On BSE, companies also have numerical

security codes and names.

Beginners should verify the exact security, exchange and series before placing an order. Similar company

names can cause avoidable mistakes.

Exchange order books generally prioritise better prices first. When multiple orders have the same price,

earlier orders normally receive priority.

This creates an orderly and transparent method for matching orders.

Indian equity markets operate during exchange-declared sessions on business days, excluding market

holidays.

There may be pre-open, normal-market and special sessions. Exact timings and procedures can change, so

users should rely on current exchange and broker information.

Trading is the agreement to buy or sell. Clearing determines the obligations of the buyer and seller.

Settlement completes the exchange of securities and funds.

Clearing corporations stand between market participants and reduce counterparty risk through defined

systems and safeguards.

The same stock may have greater trading activity on one exchange than the other.

Higher liquidity generally means more orders, narrower spreads and easier execution.

A beginner should inspect the available depth and spread rather than choosing an exchange blindly.

NSE maintains indices such as the Nifty family. BSE maintains indices such as the Sensex family.

An index is a calculated measure, not an account or a company. It represents the performance of a selected

group of securities.

An exchange provides infrastructure and market regulation. Listing does not mean that the exchange

guarantees a company's quality, profitability or future price performance.

A listed security can still decline sharply or become illiquid.
