Islem Bazlý Manipulasyonun Istatistiksel Siniflandýrma Analizleriyle Belirlenmesi
AbstractThe trade based manipulation has negative effects on investors, stock market and so, depending on them on whole economy. Consequently, a study based on determination of manipulation will provide information to related individuals. The goal of this study is evaluating the usability of financial ratios in trade based manipulation as an indicator when the investors make the stock selection decision. To make this evaluation Logistic Regression and Discriminant Analysis are used. In the study, the data between the years 1996-2005 that about trade based manipulation are gained from the Istanbul Stock Exchange and the financial ratios are calculated. These ratios are formed as independent variables in the analysis. Beside the independent variables, the dependent variable is coded as dichotomous “0” and “1” according to the trade based manipulation’s realization case. According to the analysis, we reach the conclusion as the independent variables of “Return on Assets” and “Book Value per Share” are the important financial ratios to determine the trade based manipulation.
