Assuming the underlying assets follow a Variance-Gamma (VG) process, we consider the problem of estimating gradients of a European call option by Monte Carlo simulation methods. In this paper, we compare indirect methods (finite difference techniques such as forward differences) and two direct...

This paper empirically examines the relationship between trading volume and conditional volatility of returns in the Tunisian stock market within the framework of the mixture of distribution hypothesis (MDH) and the sequential information arrival hypothesis (SIAH). Through this study, we...

Equity basket correlation is an important risk factor. It characterizes the strength of linear dependence between assets and thus measures the degree of portfolio diversification. It can be estimated both under the physical measure from return series, and under the risk neutral measure from...

This paper studies the intertemporal relation between U.S. volatility risk and international equity risk premia. We show that a common volatility risk factor constructed from the option-implied U.S. forward variances positively and significantly predicts future stock market returns of the...

This paper reviews the findings from academia and financial industry from a practical angle, attempting to outline the ‘messages’ which could inform and help the risk community to build practical equity-credit models for counterparty risk. This review covers published material and, where...

Existing models of option returns neglect the distribution of expected underlying asset volatility. An ensemble of six common GARCH models affords estimates of the moments of the physical—rather than the risk-neutral—distribution of anticipated—instead of historical—volatility, as well...
