Development of high-frequency volatility estimators in pricing and trading stock options
Asset return volatility plays a key role in derivative pricing and hedging, risk management and portfolio allocation decisions. This study examined the economic benefit of high-frequency volatility estimators (measures realized) in option pricing and ...

Realizing Smiles: Options Pricing with Realized Volatility [PDF]
We develop a discrete-time stochastic volatility option pricing model exploiting the information contained in the Realized Volatility (RV), which is used as a proxy of the unobservable log-return volatility. We model the RV dynamics by a simple and effective long-memory process, whose parameters can be easily estimated using historical data.

Forecasting realized volatility: The role of implied volatility, leverage effect, overnight returns, and volatility of realized volatility [PDF]
AbstractWe forecast realized volatility extending the heterogeneous autoregressive model (HAR) to include implied volatility (IV), the leverage effect, overnight returns, and the volatility of realized volatility. We analyze 10 international stock indices finding that, although a simple HAR model augmented with IV (HAR‐IV) is more accurate than any HAR

The dual effect of idiosyncratic volatility on stock pricing and return
This study aims to examine what underlies the estimated relation between idiosyncratic volatility and realized return. Idiosyncratic volatility has a dual effect on stock pricing: it not only affects investors' expected return but also affects the ...

Multivariate Stochastic Volatility Model With Realized Volatilities and Pairwise Realized Correlations [PDF]
Although stochastic volatility and GARCH (generalized autoregressive conditional heteroscedasticity) models have successfully described the volatility dynamics of univariate asset returns, extending them to the multivariate models with dynamic correlations has been difficult due to several major problems.

The study of high-frequency financial data has been one of the most rapidly evolving areas of research over the last decade. We have seen an explosive growth in the availability of such data, which has gone hand in hand with the development of theory for how to analyze the data.

Realized Volatility and Overnight Returns [PDF]
No consensus has emerged on how to deal with overnight returns when calculating realized volatility in markets where trading does not take place 24 hours a day. This paper explores several common volatility applications, investigating how the chosen treatment of overnight returns affects the results.
