There are two main types of stock: common stock and preferred stock.
Common stock is the most common type of stock. Holders of common stock have voting rights at shareholder meetings and may receive dividends, which are payments made by the company to its shareholders.
Preferred stock is a type of stock that has a higher claim on the company's assets and earnings than common stock. Holders of preferred stock typically do not have voting rights, but they may receive dividends at a fixed rate or have the right to be paid before common stockholders in the event that the company goes bankrupt or is liquidated.
