Abstract

In continuation of the article " Risk-neutral dynamics for the ARIMA-GARCH (autoregressive integrated moving average - generalized autoregressive conditional heteroskedasticity) random process with errors distributed according to the Johnson's SU law," this paper presents the experimental results for the ARIMA-GARCH (autoregressive integrated moving average - generalized autoregressive conditional heteroskedasticity) models with normal (N), exponential beta ofthe second type (EGB2), and SU Johnson (JSU) error distributions. The fair value of European options is estimated by the Monte-Carlo method based on the results obtained in the specified article by using the extended Girsanov principle. The parameters of the ARIMA-GARCH-N, ARIMA-GARCH-EGB2, and ARIMA-GARCH-JSU models were found by the quasi-maximum likelihood method. The efficiency of the resulting risk-neutral models was studied using the example of European exchange-traded options PUT and CALL on basic assets DAX and Light Sweet Crude Oil.
