We propose a joint modeling strategy for timing the joint distribution of the returns and their volatility. We do this … volatility, allowing for asymmetric cross-correlations, denoted as instantaneous leverage effects, in addition to cross …-autocorrelations between returns and volatility, denoted as intertemporal leverage effects. We show that while the conventional intertemporal …

Using high-frequency data, we decompose the time-varying beta for stocks into beta for continuous systematic risk and beta for discontinuous systematic risk. Estimated discontinuous betas for S&P500 constituents between 2003 and 2011 generally exceed the corresponding continuous betas. We...

It provides a more flexible modelling of the volatility than the HEAVY models …. A joint quasi-maximum likelihood estimation and closed form multi-step ahead forecasting is derived. The model is …

We propose a novel factor model for option returns. Option exposures are estimated nonparametrically and factor risk premia can vary nonlinearly with states. The model is estimated using regressions, with minimal assumptions on factor and option return dynamics. Using index options, we...

This paper examines how the size of the rolling window, and the frequency used in moving average (MA) trading strategies, affects financial performance when risk is measured. We use the MA rule for market timing, that is, for when to buy stocks and when to shift to the risk-free rate. The...

Sellers of variance swaps earn time-varying risk premia for their exposure to realized variance, the level of variance swap rates, and the slope of the variance swap curve. To measure risk premia, we estimate a dynamic term structure model that decomposes variance swap rates into expected...
