Abstract:

This paper makes an attempt to decompose the Black – Scholes into components in Garch option model, and to examine the path of dependence in the terminal stock price distribution of Amman Stock Exchange (ASE), such as Black – Scholes’, the leverage effect in this paper which represents the result of analysis is important to determine the direction of the model bias, a time varying risk, may give fruitful help in explaining the under pricing of traded stock sheers and traded options in ASE. Generally, this study considers various pricing bias related to warrant of strike prices, and observes time to time maturity. The Garch option price does not seem overly sensitive to (a, B1) parameters, or to the time risk premium variance persistence parameter, Ω = a1+B1, heaving on the magnitude of Black –Scholes’ bias of the result of analysis, where the conditional variance bias does not improve in accuracy to justify the model to ASE data. Key Words: ASE, Black-Scholes, Garch model, Option Prices, Stochastic volatility, Strike Prices.
