What is the Role of a Stock Exchange?

A stock exchange is like a big online marketplace where people buy and sell shares of public companies, bonds, and other financial products like ETFs (Exchange-Traded Funds). It’s a regulated platform that makes trading safe, smooth, and transparent for both buyers and sellers.

In India, stock exchanges are regulated by SEBI (Securities and Exchange Board of India). SEBI ensures the market is fair, protects investors, and helps the capital markets grow in an organized way.

🛠️ How Does a Stock Exchange Work?

In India, stock exchanges run on an electronic system. Here’s how it works:

You tell your broker you want to buy a stock.
Your broker sends your request to the exchange.
The exchange matches your request with someone selling that stock.
Once matched, the deal is confirmed, and the trade is completed.

This system is order-driven, meaning trades are based on matching buy and sell orders automatically. It helps keep everything transparent—everyone can see the market price and available orders in real-time.

🎯 Main Purpose of Stock Exchanges

At their core, stock exchanges help businesses grow and give investors opportunities. They:

Help companies raise money via IPOs (Initial Public Offerings).
Promote transparency, since listed companies must regularly report their performance.
Encourage smart use of money—instead of sitting idle, capital flows into productive businesses.
Offer investment choices through primary (IPO) and secondary markets.

📈 How You Can Invest in Stocks

You can invest in the Indian stock market in two ways:

1. Primary Market

This is where companies sell shares for the first time (like in an IPO).
You get to buy directly from the company.

2. Secondary Market

Here, you buy and sell shares that are already listed.
You’re trading with other investors, not the company itself.

Depending on the method, the market may operate through auction-style systems or dealer-based systems.
