(This abstract was borrowed from another version of this item.) Suggested Citation The empirical results show convincingly that realised volatility models produce far more accurate volatility forecasts compared to models based on daily returns. A stationary bootstrap procedure is required for computing the test statistic and its $p$-value. Since volatilities are not observed, realised volatility is taken as a proxy for actual volatility and is used for computing the forecast error. In particular, we will use superior predictive ability tests to investigate the relative forecast performances of some models. The forecast assessment is based on the hypothesis of whether a forecast model is outperformed by alternative models. The main focus is on forecasting the daily variability of the Standard & Poor's 100 stock index series for which trading data (tick by tick) of almost seven years is analysed. These historical volatility models are extended to include realised and implied volatility measures as explanatory variables for volatility. The predictive abilities of realised volatility models are compared with those of stochastic volatility models and generalised autoregressive conditional heteroskedasticity models for daily return series.

First we consider unobserved components and long memory models for realised volatility which is regarded as an accurate estimator of volatility. In this paper we explore the forecasting value of historical volatility (extracted from daily return series), of implied volatility (extracted from option pricing data) and of realised volatility (computed as the sum of squared high frequency returns within a day). The increasing availability of financial market data at intraday frequencies has not only led to the development of improved volatility measurements but has also inspired research into their potential value as an information source for volatility forecasting. This discussion paper resulted in an article in the Journal of Empirical Finance (2005).
