In this paper we investigate portfolio optimization under Value at Risk, Average Value at Risk and Limited Expected … Value at Risk, Average Value at Risk and Limited Expected Loss are derived. We solve the problem of minimizing risk measures … applied to portfolios. Moreover, the portfolio’s expected return is maximized subject to the aforementioned risk measures. We …

Cushioning against risk has always created a plethora of complexities and challenges; hence …, this paper attempts to analyse statistical properties of various risk measures in a not normal distribution and provide a …

Portfolio risk management plays an important role in successful investments. Portfolio standard deviation, value-at-risk …, expected shortfall, and maximum absolute deviation are widely used portfolio risk measures. However, the existing portfolio … risk measures are vulnerable to larger skewness and kurtosis of the asset returns. Moreover, the traditional assumption of …

This paper examines a simple basis risk model based on correlated geometric Brownian motions. We apply quadratic … criteria to minimize basis risk and hedge in an optimal manner. Initially, we derive the Föllmer–Schweizer decomposition for a … European claim. This allows pricing and hedging under the minimal martingale measure, corresponding to the local risk …

The paper compares portfolio optimization with the Second-Order Stochastic Dominance (SSD) constraints with mean-variance and minimum variance portfolio optimization. As a distribution-free decision rule, stochastic dominance takes into account the entire distribution of return rather than some...

Systemic risk is the risk that the distress of one or more institutions trigger a collapse of the entire financial … system. We extend CoVaR (value-at-risk conditioned on an institution) and CoCVaR (conditional value-at-risk conditioned on an … institution) systemic risk contribution measures and propose a new CoCDaR (conditional drawdown-at-risk conditioned on an …
