Modelling and Forecasting Noisy Realized Volatility [PDF]
SSRN Electronic Journal, 2009 Several methods have recently been proposed in the ultra high frequency financial literature to remove the effects of microstructure noise and to obtain consistent estimates of the integrated volatility (IV) as a measure of ex-post daily volatility. Even

"Asymmetry and Leverage in Realized Volatility" [PDF]
SSRN Electronic Journal, 2009 A wide variety of conditional and stochastic variance models has been used to estimate latent volatility (or risk). In both the conditional and stochastic volatility literature, there has been some confusion between the definitions of asymmetry and ...

Enhancing Prediction by Incorporating Entropy Loss in Volatility Forecasting [PDF]
EntropyIn this paper, we propose examining Heterogeneous Autoregressive (HAR) models using five different estimation techniques and four different estimation horizons to decide which performs better in terms of forecasting accuracy. Several different estimators

Modeling Realized Variance with Realized Quarticity
Stats, 2022 This paper proposes a model for realized variance that exploits information in realized quarticity. The realized variance and quarticity measures are both highly persistent and highly correlated with each other.

Analysis of Option Trading Strategies Based on the Relation of Implied and Realized S&P500 Volatilities [PDF]
ACRN Journal of Finance and Risk Perspectives, 2021 In this paper, we examine the performance of certain short option trading strategies on the S&P500 with backtesting based on historical option price data. Some of these strategies show significant outperformance in relation to the S&P500 index.

Challenges of integrated variance estimation in emerging stock markets [PDF]
Zbornik radova Ekonomskog fakulteta u Rijeci : časopis za ekonomsku teoriju i praksu, 2019 Estimating integrated variance, using high frequency data, requires modelling experience and data crunching skills. Although intraday returns have attracted much attention in recent years, handling these data is challenging because of their ...

Estimation of Realized Asymmetric Stochastic Volatility Models Using Kalman Filter
Econometrics, 2023 Despite the growing interest in realized stochastic volatility models, their estimation techniques, such as simulated maximum likelihood (SML), are computationally intensive.
