Effect of Capital Structure on Profitability of Securities Companies: Empirical Research in Vietnam

Capital structure is understood as the proportion of each source of capital in the total capital that the business, or the combination of debt and equity that the company uses for business operations. The decision on capital structure is one of the important financial decisions for any business, reducing capital costs and eliminate unwanted risks. In other words, a reasonable structure is the balance between risk and profit, from which enterprises can implement their business strategies. In fact, the capital structure of each enterprise depends on many factors such as the macro conditions of each country, each industry in which the enterprise operates, or the individual characteristics of each enterprise, etc., so there is no single structure common to all businesses. Therefore, the study of capital structure is a topic that is always interested by scientists at different stages, as well as business managers to make effective selection decisions.
