A Stock (or Share) represents ownership in a company and a claim on a part of its assets and profits.
When you buy a stock, you become a shareholder (part-owner) of the company. Stocks are traded on exchanges like the National Stock Exchange and Bombay Stock Exchange, regulated by the Securities and Exchange Board of India.
Companies issue stocks to raise capital, and investors buy them to earn returns through price appreciation and dividends.
"If you buy shares of a company at ₹100 and sell at ₹120, you earn a ₹20 profit per share."
