An Application Based on Sports Clubs Traded at BIST through Value at Risk Methods

16116

In terms of stock investors, with the expected return, one of the most sensitive point is to predict the greatest financial losses which a portfolio could give investor. In this study, using value at risk calculation methods such as Var, Historical Simulation and EWMA method two different virtual portfolios formed from the sports clubs stocks which are traded at BIST in Turkey, have been studied. Although, at the result of the analysis Historical Simulation method had the lowest estimate, at the result of the retrospective tests its effectiveness was lower. According to the retrospective test results, maximum efficiency has emerged in the Var. Var method requires the assumption of normality assumption so calculations have been made under this assumption.As the other two methods do not require normality and constant varience constraints, there was no need such an assumption. As a result, under the assumption of constant variance and normal distribution, Var method has the most effective estimate.
