Shares are units of ownership interest in a corporation or financial asset that provide for an equal distribution in any profits, if any are declared, in the form of dividends. The two main types of shares are common shares and preferred shares. Physical paper stock certificates have been replaced with electronic recording of stock shares, just as mutual fund shares are recorded electronically.
