Lambda Value at Risk and Regulatory Capital: A Dynamic Approach to Tail Risk [PDF]
Risks, 2018 This paper presents the first methodological proposal of estimation of the Λ V a R . Our approach is dynamic and calibrated to market extreme scenarios, incorporating the need of regulators and financial institutions in more sensitive risk ...

On Conditional Value at Risk (CoVaR) for tail-dependent copulas
Dependence Modeling, 2017 The paper deals with Conditional Value at Risk (CoVaR) for copulas with nontrivial tail dependence. We show that both in the standard and the modified settings, the tail dependence function determines the limiting properties of CoVaR as the conditioning ...

Value-at-Risk, Tail Value-at-Risk and upper tail transform of the sum of two counter-monotonic random variables [PDF]
Scandinavian Actuarial Journal, 2022 The Value-at-Risk (VaR) of comonotonic sums can be decomposed into marginal VaR's at the same level. This additivity property allows to derive useful decompositions for other risk measures. In particular, the Tail Value-at-Risk (TVaR) and the upper tail transform of comonotonic sums can be written as the sum of their corresponding marginal risk ...

On Partial Stochastic Comparisons Based on Tail Values at Risk [PDF]
Mathematics, 2020 The tail value at risk at level p, with p ∈ ( 0 , 1 ) , is a risk measure that captures the tail risk of losses and asset return distributions beyond the p quantile. Given two distributions, it can be used to decide which is riskier.

Portfolio Tail Risk: A Multivariate Extreme Value Theory Approach [PDF]
Entropy, 2020 This paper develops a method for assessing portfolio tail risk based on extreme value theory. The technique applies separate estimations of univariate series and allows for closed-form expressions for Value at Risk and Expected Shortfall. Its forecasting

The effect of Size, Value and Idiosyncratic Risk Anomalies on the Relationship between Tail Risk and Stock Excess Returns [PDF]
Iranian Journal of Accounting, Auditing & Finance, 2022 Capital market anomalies are caused by factors haven’t been considered in capital asset pricing models. The theories of extreme value are one of the arguments for explaining anomalies.

Tail Value-at-Risk-Based Expectiles for Extreme Risks and Their Application in Distributionally Robust Portfolio Selections [PDF]
Mathematics, 2022 Empirical evidence suggests that financial risk has a heavy-tailed profile. Motivated by recent advances in the generalized quantile risk measure, we propose the tail value-at-risk (TVaR)-based expectile, which can capture the tail risk compared with the

A predictive approach to quantiles: Application to Value at Risk and Tail Value at Risk
Probability and Mathematical StatisticsSummary: We prove that quantiles are best predictors in a special metric. The best predictor turns out to coincide with the notions of generalized arithmetic mean, exponential barycenter and certainty equivalent. We also show that the computation of tail value at risk (TVaR) reduces to the computation of a quantile with a higher level of confidence ...

Risk Comparison in Optimal Portfolios: A Study of Value at Risk (VaR) and Tail Value at Risk (TVaR)
Mathematical Journal of Modelling and ForecastingConsidering investment risk is something that investors must do before deciding to invest; measuring risk provides an opportunity for investors to get the desired return and minimize losses. This study compares Value at Risk (VaR) and Tail Value at Risk (TVaR) methodologies for measuring portfolio risk.
