摘要

Previous studies have documented that, with use of high-frequency data, the Heteroskedasticity AR (HAR- RV) model performs better than other models in fitting financial return volatility measurement and has a more accurate forecasting ability. However, to our knowledge, no previous studies have investigated whether HAR-RV model can improve option pricing performance in financial markets. This study compares HAR-RV model and EGARCH model in terms of option pricing performance. As expected, the results of this study demonstrate that HAR-RV model is more accurate than EGARCH model in terms of S&P500 Index options (SPX) and Dow Jones Index options (DIX).
