The stock market refers to exchanges where public trading of company stocks and bonds occurs. It allows companies to raise money and for businesses to become publicly traded. In India, most trading occurs on two major exchanges - the Bombay Stock Exchange and the National Stock Exchange. The BSE is the oldest stock exchange in Asia, while the NSE introduced electronic trading and created important indices like Nifty 50. Regulatory bodies like the Securities and Exchange Board of India oversee the market and protect investors. Individuals can invest in different assets like stocks, mutual funds, bonds, and more through trading accounts and depository services. Fundamental and technical analysis help investors evaluate market and investment opportunities.
