Functions of Stock Market

The main functions of the stock market include capital formation, liquidity, price discovery, risk diversification, corporate governance, and providing benchmarks for market performance.

• Companies can raise capital by issuing shares to investors.
• Investors can buy and sell securities through organised stock exchanges.
• Market prices are determined through demand and supply.
• BSE was established in 1875 and is Asia’s oldest stock exchange.
• NSE was incorporated in 1992 and began operations in 1994.
• The BSE Sensex tracks 30 large, liquid, and financially sound companies listed on BSE.
• The Nifty 50 includes 50 stocks representing important sectors of the Indian economy.
• Stock market indices can help investors compare portfolio and market performance.

The Indian stock market has two major stock exchanges, BSE and NSE. Both provide platforms where investors and traders can transact in different types of securities.

BSE

BSE, formerly known as the Bombay Stock Exchange, was established in 1875. It is Asia’s oldest stock exchange and provides a platform for trading in equity shares, debt instruments, mutual funds, and derivatives.

The Bombay Stock Exchange plays an important role in India’s capital markets. The BSE Sensex is a major benchmark index. It measures the performance of 30 large, liquid, and financially sound companies listed on BSE.

NSE

The National Stock Exchange, or NSE, was incorporated in 1992 and began operations in 1994. It was the first stock exchange in India to introduce electronic or screen-based trading.

The functions of the National Stock Exchange include providing a marketplace for equity, debt, derivatives, and other securities.

The Nifty 50 is NSE’s major benchmark index. It consists of 50 stocks representing important sectors of the Indian economy and is calculated using the free-float market-capitalisation-weighted method.

Stock markets perform several important functions for companies, investors, and the financial system.

1. Capital formation

Stock markets help companies raise money for requirements such as business expansion, research and development, and new projects.

Companies can issue shares to investors to raise capital. These securities can then be listed and traded on a stock exchange.

For example, a company that needs funds for a new factory may raise part of the required capital by issuing shares.

2. Liquidity

A stock market brings buyers and sellers together on an organised trading platform. This makes it easier for investors to buy or sell listed securities when there is sufficient market demand.

Liquidity can help investors convert investments into cash or exit a position. However, the level of liquidity can vary between securities.

For example, a frequently traded large-company stock may usually have more buyers and sellers than a stock that trades only occasionally.

3. Price discovery

Price discovery is one of the key functions of a stock market. The market price of a security changes according to demand and supply.

Buyers place prices at which they are willing to buy, while sellers indicate prices at which they are willing to sell. Their interaction helps establish the security’s market price.

These prices may also reflect investors’ views about a company’s current position and future prospects.

4. Wealth creation

Stock markets allow investors to participate in the growth of listed companies through market-linked investments.

If the market value of an investment rises over time, investors may benefit from capital appreciation. However, market returns are not guaranteed, and investment values can also fall.

For example, if you purchase a share at ₹100 and its market price later rises to ₹120, the increase of ₹20 represents capital appreciation before costs and taxes.

5. Dividend income

The share market can also provide investors with dividend income.

Some companies distribute part of their profits to shareholders as dividends. However, dividends are not guaranteed and depend on factors such as the company’s profits, financial position, and dividend policy.

For example, if a company declares a dividend, eligible shareholders receive the amount according to the number of shares they hold.

6. Transferring risk

Stock market investments involve risk because the value of securities can rise or fall.

Certain market instruments, particularly derivatives, can be used to transfer or manage specific types of market risk between participants. However, using these instruments can also involve additional risks.

7. Risk diversification

Stock markets give investors access to different securities and sectors. This can help them spread their investments rather than concentrating all their money in one company or sector.

Investors may diversify across instruments such as stocks, bonds, derivatives, and mutual funds.

For example, holding shares from several sectors may reduce the effect that poor performance in one company or sector has on the overall portfolio. Diversification can reduce concentration risk, but it cannot remove all investment risk.

8. Corporate governance and control

Owning shares in a company gives shareholders certain ownership rights.

Depending on the type of shares and applicable rules, shareholders may have voting rights on matters such as the appointment of directors and other important company resolutions.

These rights can improve accountability by allowing shareholders to participate in certain corporate decisions.

9. Benchmark for performance

Stock market indices such as the S&P BSE Sensex, Nifty 50, BSE Midcap, and BSE 100 can be used as performance benchmarks.

Broad-market indices such as the Nifty 50 show the performance of a group of major stocks. Sector-specific indices, such as the Nifty IT index, track particular market segments.

You can compare your portfolio’s returns with a relevant index to understand how it has performed relative to that benchmark.

10. Economic indicator

Stock market movements are sometimes used as one of several indicators of economic expectations and investor sentiment.

A rising market may reflect stronger investor confidence or expectations of better business conditions. A falling market may reflect concerns about companies, economic conditions, interest rates, or other factors.

However, stock market performance does not always move in the same direction as the broader economy.

11. Market efficiency

Market efficiency refers to how quickly available and relevant information is reflected in security prices.

When new information about a company becomes available, investors may respond by buying or selling its shares. These transactions can cause the market price to change.

This is one reason why consistently outperforming the market only through share market timing can be difficult.

The stock market plays an important role in connecting companies that need capital with investors who want to participate in financial markets. Its key functions include capital formation, liquidity, price discovery, diversification, corporate governance, and performance benchmarking. Stock exchanges also help investors buy and sell securities in an organised marketplace. However, stock market investments involve risk, and returns are not guaranteed. Understanding these functions can help investors better understand how the market operates and supports the wider economy.
