Implied volatility from the Black and Scholes (Journal of Political Economy 81, 1973, p. 637) model has been empirically analyzed for the forecasting performance of future volatility and is well known to be biased. Based on the belief that implied volatility from option prices can best estimate future volatility, this study identifies the best way to derive implied volatility to overcome the forecast bias associated with the BlackScholes model. For this, the following three models are considered: Hestons model, which best addresses the problems associated with the BlackScholes model for pricing and hedging options; Britten-Jones and Neubergers model-free implied volatility (MFIV), which eliminates the model-oriented bias; and VKOSPI, the Korean version of the Chicago Board Options Exchange Market Volatility Index. This study conducts a comparative analysis of implied volatilities from the BlackScholes model, Hestons model, the MFIV, and VKOSPI for their abilities to forecast future volatility. The results of the empirical analysis of the KOSPI 200 options market indicate that Hestons model can eliminate most of the bias associated with the BlackScholes model, whereas the MFIV and VKOSPI do not show any improvement in terms of forecasting performance.
