Investment and financial policy of companies facilitate getting additional resources for financing and strengthen their financial status. Various methods have been developed so far, and there are a lot of financial coefficients by which one can evaluate and mark not only financial but also industrial potential of companies. But every region of the Russian Federation and every industry have specificities that are very difficult to take into account in defining regulatory meaning of financial indicators. That is why, the authors suggest forming a single financial indicator, and they have analyzed some companies of the oil and gas sector of Tomsk region. In the authors’ viewpoint, the consolidated financial indicator allows assessing and analysing comprehensively the level of competitiveness of business entities. The obtained rating revealed that the first places belong to truly successful companies, which in fact undertake managing activity. The last places belong to the companies that do not manufacture goods, do not have any managerial and production expenditures. In this connection, the subsequent study and construction of an optimum business strategy is possible based on the constructed rating and comprehensive study of the leaders. The knowledge of factors, influencing the functioning of the organisation negatively, allows the agents of management to elaborate managerial decisions, correcting the managerial process. The number of taken corrective managerial decisions depends on the quality of managerial decisions made, which will lead to the change in the company’s position in the composite rating.
