Measuring the risk of a financial portfolio involves two steps: estimating the loss distribution of the portfolio from available observations and computing a ‘risk measure’ that summarizes the risk of the portfolio. We define the notion of ‘risk measurement procedure’, which includes both of these steps, and introduce a rigorous framework for studying the robustness of risk measurement procedures and their sensitivity to changes in the data set. Our results point to a conflict between the… 

Robustness in the Optimization of Risk Measures

It is discovered that for many simple representative optimization problems, VaR generally leads to non-robust optimizers whereas ES generally leadsto robust ones.

Loss-based risk measures

Abstract Starting from the requirement that risk of financial portfolios should be measured in terms of their losses, not their gains, we define the notion of loss-based risk measure and study the

Model Uncertainty in Risk Capital Measurement

The required solvency capital for a financial portfolio is typically given by a tail risk measure such as Value-at-Risk. Estimating the value of that risk measure from a limited, often small, sample

The measurement of financial risk has been one of the main goals of the investors as well as actuaries and insurance practitioners. Measuring the risk of a financial portfolio involves firstly

Parameter Uncertainty and Residual Estimation Risk

The notion of residual estimation risk is introduced in order to study the impact of parameter uncertainty on capital adequacy, for a given risk measure and capital estimation procedure. Residual

The Wasserstein Metric and Robustness in Risk Management

In the aftermath of the financial crisis, it was realized that the mathematical models used for the valuation of financial instruments and the quantification of risk inherent in portfolios consisting

Verification of internal risk measure estimates

It is shown in particular that VaR has special properties not shared by any other risk measure, and it is argued that its main deficiency is the unquantifiable tail dependence of estimators.

Robust and Practical Estimation for Measures of Tail Risk

We describe characteristics of various risk measures (Value-at-Risk, Expected Shortfall, etc.) that are used to analyze and quantify the tail risk exposure, and discuss their relative strengths and

Risk Measures: Statistical Estimation

This article presents the main risk measures suggested in the current regulations for finance (Basel 2) and insurance (Solvency 2) to fix the reserves, which are the Value-at-Risk (VaR), Tail-VaR,

Aggregation-robustness and model uncertainty of regulatory risk measures

It turns out that coherent risk measures, such as ES, are more robust than VaR according to the new notion of robustness, and it is obtained that for a portfolio of a large number of risks, VaR generally has a larger uncertainty spread compared to ES.

Sensitivity Analysis of Distortion Risk Measures

This paper provides a uni¯ed statistical framework for the analysis of distortion riskmeasures (DRM) and of their sensitivities with respect to parameters representing riskaversion and/or pessimism.

What Is a Good External Risk Measure: Bridging the Gaps between Robustness, Subadditivity, and Insurance Risk Measures

Choosing a proper risk measure is of great regulatory importance, as exemplified in Basel Accord that uses Value-at-Risk (VaR) in combination with scenario analysis as a preferred risk measure. The

MODEL UNCERTAINTY AND ITS IMPACT ON THE PRICING OF DERIVATIVE INSTRUMENTS

Uncertainty on the choice of an option pricing model can lead to “model risk” in the valuation of portfolios of options. After discussing some properties which a quantitative measure of model

Coherent Measures of Risk

In this paper we study both market risks and nonmarket risks, without complete markets assumption, and discuss methods of measurement of these risks. We present and justify a set of four desirable

What Is a Good Risk Measure: Bridging the Gaps between Data, Coherent Risk Measures, and Insurance Risk Measures

Two main axiomatically based risk measures are the coherent risk measure, which assumes subadditivity for random variables, and the insurance risk measure, which assumes additivity for comonotonic

Sensitivity Analysis of Values at Risk

Extremes and Robustness: A Contradiction?

It is shown how robust methods can improve the quality of EVT data analysis by providing information on influential observations, deviating substructures and possible mis-specification of a model while guaranteeing good statistical properties over a whole set of underlying distributions around the assumed one.

The Limits of Diversification When Losses May Be Large

Recent results in value at risk analysis show that, for extremely heavy-tailed risks with unbounded distribution support, diversification may increase value at risk, and that, generally, it is

Can a Coherent Risk Measure Be Too Subadditive?

It is found that for an explicitly specified confidence level, the Value-at-Risk satisfies the regulator's condition and is the most efficient capital requirement in the sense that it minimizes some reasonable cost function.

Convex measures of risk and trading constraints

The notion of a convex measure of risk is introduced, an extension of the concept of a coherent risk measure defined in Artzner et al. (1999), and a corresponding extensions of the representation theorem in terms of probability measures on the underlying space of scenarios are proved.
