The main function of the stock market is to provide a platform where companies can raise capital and investors can buy and sell shares. It connects businesses that need funds with individuals and institutions willing to invest money for potential returns. By issuing shares to the public, companies can collect capital to expand operations, develop new products, improve infrastructure, or enter new markets. This process helps businesses grow and contributes to overall economic development.

For investors, the stock market offers opportunities to build wealth through capital appreciation and dividends. When investors purchase shares, they become partial owners of a company and may benefit if the company performs well. The stock market also provides liquidity, allowing investors to easily buy or sell their shares whenever needed. Without a stock market, converting investments into cash would be much more difficult.

Another important function of the stock market is price discovery. Share prices are determined by supply and demand, reflecting investor confidence, company performance, and economic conditions. This helps create fair market values for businesses and provides valuable information to investors and analysts.

The stock market also encourages savings and investment by offering various financial opportunities. It plays a vital role in mobilising idle funds into productive sectors of the economy. In addition, stock exchanges promote transparency, corporate governance, and investor protection through regulations and reporting requirements, making financial markets more organised, efficient, and trustworthy for participants worldwide.
