This paper provides a result on moment non-explosions for a stock following a Wishart multidimensional stochastic volatility dynamic or a Wishart affine stochastic correlation dynamic when the parameter values satisfy certain constraints. By reformulating the stock dynamic in terms of the...

We extract variance and skew risk premiums from volatility derivatives in a model-free way and analyze their relationships along with volatility index and equity index returns. These risk premiums can be synthesized through option trading strategies. Using a time series of option prices on the...

This paper studies the relationship between credit default swap spreads (CDS) for the Energy sector and oil futures dynamics. Using data on light sweet crude oil futures from 2004 to 2013, which contains a crisis period, we examine the importance of volatility and jumps extracted from the...

The objective of this paper is to perform a joint analysis of jump activity for commodities and their respective volatility indices. Exploiting the property that for affine jump-diffusion models a volatility index, which is quoted on the market, is an affine function of the instantaneous...

This paper presents a joint analysis of the term structure of credit default swap (CDS) spreads and the implied volatility surface for European countries during 2007-2012, a sample period covering both the Global Financial Crisis and the European debt crisis. We analyze to which extent...

We study the co-movement of credit and equity markets in four Asia-Pacific countries at firmand index level. First, we establish realized volatility as an important determinant of CDS spreadlevels and changes. Second, we examine lead-lag relationships between CDS spreads, volatility and stock...
