The stock market is the process of buying and selling stocks (shares) from a firm. Shares are securities listed at the exchange for stocks. If you purchase shares of a firm, you instantly become a shareholder of the company. The money you benefit from the shares you purchased in two ways. The first is by the dividends given by the company to shareholders. Another way to earn money is by the increase in the value of the business. Based on the kind of stocks you bought the dividends are generally determined on a fixed and variable.
