On the one hand, the stockholders of a company are those who buy a stock or share of the company in order to make money by investing in that stock. When an investor owns that stock he can decide between keeping it in order to obtain dividends later or to sell it by a higher price as well later.
On the other hand, a bondholder of a company is the person who decides to buy a bond from the company and that action focus on the lending of money from the boldholder to the company who agrees to return that money later with interest. In a case of bankrupcy, bondholders are the ones who are paid first.
