Common stock represents the amount of capital paid or invested in a company by the investors. This stock provides the holder with the authorization to vote in the annual general meetings to elect the board of directors. The voting rights are connected to the stocks, which equals one vote per share.
These stocks allow the shareholders to involve themselves in the business of growth and profits.Preferred stock, on the other hand, is special financial instruments that perform as equity and debt. Specific payment terms are linked with preferred stocks, which is why these shares take precedence over common stock at the time of insolvency, or when the dividends are allocated among the shareholders.
Preferred shares do not have any voting privileges attached to them. Preferred stocks are rated by credit agencies just like bonds, while common stocks are not rated by any credit agency.
