The Securities Market is a platform where financial instruments like stocks, bonds, and mutual funds are bought and sold. It allows companies to raise capital by issuing shares, while investors can purchase these securities to potentially earn returns. The market is divided into primary and secondary markets, with the primary market dealing with new issues and the secondary market facilitating the trading of existing securities. Investors participate in the securities market through various exchanges, such as the New York Stock Exchange or the NASDAQ. Regulatory bodies like the Securities and Exchange Commission (SEC) oversee the market to ensure fair practices and protect investors.
