This allows an analysis of the risk properties of systems to be carefully attributed between … choices of risk function (e.g. VaR vs CVaR); choice of return distribution (power law tail vs Gaussian) and choice of event … frequency, for risk assessment. We exploit this to provide a simple method for portfolio optimization when the asset returns …

Today's asset management academia and practice is dominated by mean-variance thinking. In consequence, this leads to the quantification of the dependence structure of asset returns by the covariance or the Pearson's correlation coefficient matrix. However, the respective dependence measures are...

Interconnectedness is an alternative risk concept that so far has earned little attention in the asset management … academia and industry. In this paper, we show that this neglect is not justified, as interconnectedness risk (i) has only … interconnectedness information outperform their conventional peers. Utilizing a multi asset dataset, we measure interconnectedness risk …

Measures of model risk based on the residual error from hedging in a misspecified model were recently proposed in … model risk for the original market. If the market can not be completed, as it is the case in most market models that allow … for jumps, we derive measures that are applicable in a more general setup. In a case study we measure the model risk that …
