We identify a global risk factor in the cross-section of implied volatility returns in currency markets. A zero …-cost strategy that buys forward volatility agreements with downward sloping implied volatility curves and sells those with upward … slopes - volatility carry strategy - generates significant excess returns. The covariation with volatility carry returns …

This paper proposes structured parametrizations for multivariate volatility models, which use spatial weight matrices … models as well as for Stochastic- and Realized-Volatility models. The paper also discusses how to construct spatial weight …

In many multivariate volatility models, the number of parameters increases faster than the cross-section dimension …

In this paper, we review the most common specifications of discrete-time stochastic volatility (SV) models and … indices and foreign exchange rates. -- Stochastic volatility ; Markov chain Monte Carlo ; Metropolis-Hastings algorithm Jump …

This paper examines the cross section of options implied volatility and corporate bond returns. We document a strong … predictive ability of corporate bond returns using changes in call and put options implied volatility. Specifically, a strategy … of buying (selling) the portfolio with lowest (highest) changes in options implied volatility yields an average monthly …
