Research Abstract

The purpose of this paper is to recapitulate the previous theoretical achievements on the GARCH option pricing with conditional non-normality in a unified framework and provide the empirical evidence that incorporating the exponential generalized beta distribution of the second(EGB2) innovation in lieu of the normal innovation contributes to the improvement of pricing performance. We confirm the empirical relevance of the NGARCH-EGB2 option pricing model, using the S & P 500 index options data on every Wednesday from January 2, 2002 to December 27, 2006.
