Investigation of properties and branches disputes of financial ratios of greek companies
Ποντικού, Μαρία Μ.
The purpose of this study is to examine the characteristics of statistical distributions of 13 commonly used financial ratios derived from 8 branches listed Greek enterprises and the investigation of branch disputes of these financial ratios. The chosen financial ratios represent the 4 main categories of financial characteristics of a company which is liquidity, profitability, activity and capital structure. Initially, the case was examined normality, which showed that the distributions of the ratios can be considered normal in the majority of cases, either as such or after transformation into logarithmic values, or after transformation of the square root and the process of cleavage outliers. These results are in harmony with those of similar empirical investigations. Then the analysis of variance (ANOVA, Kruskall-Wallis test) applied, to examine whether the ratios between branch indices differ. The results suggest that each index has different prices for different branches. This finding justifies the practice of using branch ratios as benchmarks for evaluating of the business.
