Determination of the key financial ratios in the success of firms in different sectors through data mining

The aim of the study is to determine the significant financial ratios for the companies operating in different sectors in the year 2016. Within the scope of the research, the financial ratios of the companies operating in the retail and manufacturing sectors, which were traded at the BIST in 2016, were calculated and a mix model was created to help calculate the credit score by using both traditional and new models in determining the success and failure of the firms. In the estimation of the financial situation of the firms, discriminant analysis from the traditional methods is used and the z-score model developed by Altman is taken into consideration. Decision trees are applied from the new models for determination of the effects of rates on financial condition. As a result of this study, the financial ratios in the sectors have revealed the importance of determining the financial situation of firms.
