APPLICATION OF SKEWNESS IN PASSING OF ARCH-GARCH MODEL COMMENCE FOR CURRENCY PORTFOLIOS

Abstract

The paper uses Coskewness as risk measure, average return and gives detail of efficient skewness (gamma) of a diversity of currency portfolios. This paper also applies ARCH-GARCH model, significant properties of GARCH allow to efficient modeling financial time series having obese conclusions. Then, we connect Coskewness with ARCH-GARCH models to optimize currency portfolio. To conclude, an empirical study of ten currency portfolios from Pakistan currency exchange market is performed and all the results suggest that Coskewness can better characterized the risk-adjustment and average variance and the performance of ARCH-GARCH model is better than that of ARIMA model in portfolio optimization.
