Optimal Combination of Three Volatilities for Better Black-Scholes Option Pricing
Abstract
The most popular parametric formula (B-S) used in pricing the European-style options is given by Black-Scholes (1973). The prediction power of (B-S) strongly rely on the accuracy of the independent variables: spot price, strike price, time to maturity, risk free interest rate and market volatility. To improve the accuracy, many volatility models are proposed. Also Day and Lewis (1992) introduced the idea of combining implied volatility and EGARCH. In this article an optimal combination of market implied volatility, GARCH(1,1), and GJR(1,1) is made, and the prediction power of B-S is doubled.
