What is a Stock Exchange? Meaning, It's Role & Features Explained

Towards the end of June 2023, the Securities and Exchange Board of India (SEBI) directed the country’s stock exchanges to extend certain basic facilities for investors.SEBI also asked them to ensure that the knowledge of officials stationed at their Investor Service Centres were upgarded.Further, the stock exchanges were asked to open additional centres even if the the existing ones were operational.Indian stock exchanges can now set up such centres either on their own or jointly with other exchanges, as per their mutual agreement.So what is a stock exchange , how does it help investors, and what is its role in the Indian economy?

A stock exchange is a regulated marketplace where individuals and businesses can buy and sell securities such as stocks, bonds , and derivatives.An exchange also acts as an intermediary, facilitating transactions between buyers and sellers, ensuring liquidity and price transparency.Buyers and sellers can trade securities listed on the stock exchanges through stockbrokers. Securities not listed are aso traded; in this case, , trading is called over-the-counter (OTC).OTC trading provides leverage to negotiate the prices and terms of purchase, but it also carries certain risks such as lower liquidity and potentially higher bid-ask spreads compared to exchange-traded securities.In a stock exchange, listing and trading of securities are based on specific rules and regulations set by that exchange and by regulatory authorities overseeing its operations.These rules govern various aspects, including the eligibility criteria for listing securities, disclosure requirements for the companies, the trading mechanisms, and investor protection measures.In India, the leading stock exchanges are the National Stock Exchange (NSE) and the Bombay Stock Exchange (BSE) – both located in Mumbai, and both playing a pivotal role in channeling investments and enabling economic growth.

A stock exchange works as a marketplace where people buy and sell shares of publicly listed companies. In India, the stock exchange operates independently without market makers or specialists. The trading process is order-driven and electronic, conducted through a limit order book.Investors place their orders through brokers, who act as intermediaries between the investors and the stock exchange. The trading computer automatically matches buy and sell orders, ensuring transparency in transactions by displaying all market orders publicly.Both institutional investors and retail customers can access the stock exchange directly using trading terminals provided by brokers, a process known as direct market access (DMA).

The functions of a stock exchange extend beyond being a platform for trading securities. They serve as a barometer of economic activity, reflecting investor sentiment and market trends.The stock exchanges provide valuable information about the performance and valuation of listed companies, enabling investors to make informed investment decisions based on fundamental analysis, technical indicators, and market trends.But that apart, they also play an active role in the economy, as listed below:

The NSE and BSE are examples of stock exchanges operating within the Indian stock market.
