Common and Idiosyncratic Conditional Volatility Factors: Theory and Empirical Evidence [PDF]

open access: yesSSRN Electronic Journal, 2021
We propose a multiplicative dynamic factor structure for the conditional modelling of the variances of an N-dimensional vector of financial returns. We identify common and idiosyncratic conditional volatility factors. The econometric framework is based on an observation-driven time series model that is simple and parsimonious.

Path-Conditional Forward Volatility [PDF]

open access: yesSSRN Electronic Journal, 2006
In derivatives modelling, it has often been necessary to make assumptions about the volatility of the underlying variable over the life of the contract. This can involve specifying an exact trajectory, as in the Black and Scholes (1973), Merton (1973) or Black (1976) models; one that depends on the level of the underlying variable as in the local ...

Estimating stochastic volatility diffusion using conditional moments of integrated volatility [PDF]

open access: yesJournal of Econometrics, 2001
We exploit the distributional information contained in high-frequency intraday data in constructing a simple conditional moment estimator for stochastic volatility diffusions. The estimator is based on the analytical solutions of the first two conditional moments for the latent integrated volatility, the realization of which is effectively approximated

The conditional volatility premium on currency portfolios [PDF]

open access: yesJournal of International Financial Markets, Institutions and Money, 2021
Our paper examines conditional risk-return relations in a number of currency investment strategies, while modeling economic states using a large number of underlying risk factors. We identify a time-varying relationship between currency returns and volatility risk for most currency portfolios.

Conditional Volatility, Skewness and Kurtosis: Existence and Persistence [PDF]

open access: yes, 2001
Recent portfolio choice, asset pricing, and option valuation models highlight the importance of skewness and kurtosis. Since skewness and kurtosis are related to extreme variations, they are also important for Value-at-Risk measurements. Our framework builds on a GARCH model with a conditional generalized-t distribution for residuals.
