Optimizing Expected Shortfall under an 1 Constraint—An Analytic Approach [PDF]

open access: yesEntropy, 2021
Expected Shortfall (ES), the average loss above a high quantile, is the current financial regulatory market risk measure. Its estimation and optimization are highly unstable against sample fluctuations and become impossible above a critical ratio r=N/T ...

Implementation of a Commitment Machine for an Adaptive and Robust Expected Shortfall Estimation [PDF]

open access: yesFrontiers in Artificial Intelligence, 2021
This study proposes a metaheuristic for the selection of models among different Expected Shortfall (ES) estimation methods. The proposed approach, denominated “Commitment Machine” (CM), has a strong focus on assets cross-correlation and allows to measure

Dynamic financial tail risk networks: A backtesting-based conditional expected shortfall approach. [PDF]

open access: yesPLoS ONE
This paper develops a Factor-Copula methodology for constructing high-dimensional dynamic tail risk networks based on the conditional expected shortfall (CoES) in order to overcome the limitations of traditional quantile regression and copula models.

A Simple Traffic Light Approach to Backtesting Expected Shortfall

open access: yesRisks, 2018
We propose a Traffic Light approach to backtesting Expected Shortfall which is completely consistent with, and analogous to, the Traffic Light approach to backtesting VaR (Value at Risk) initially proposed by the Basel Committee on Banking Supervision in

On the Shortfall of Tail-Based Entropy and Its Application to Capital Allocation [PDF]

open access: yesEntropy
We introduce and study the shortfall of tail-based entropy (STE), a tail-sensitive risk functional that combines expected shortfall (ES) and tail-based entropy (TE).

On Exactitude in Financial Regulation: Value-at-Risk, Expected Shortfall, and Expectiles

open access: yesRisks, 2018
This article reviews two leading measures of financial risk and an emerging alternative. Embraced by the Basel accords, value-at-risk and expected shortfall are the leading measures of financial risk.

Nonparametric Expectile Shortfall Regression for Complex Functional Structure [PDF]

open access: yesEntropy
This paper treats the problem of risk management through a new conditional expected shortfall function. The new risk metric is defined by the expectile as the shortfall threshold.

Investigating the Effects of Strength of Corporate Governance Mechanisms on Systemic Risk for Financial Institutions Listed on Tehran Stock Exchange [PDF]

open access: yesتحقیقات مالی, 2020
Objective: The systemic risk is the risk of a crisis in the financial sector and its transmission to the economy. Due to the importance of social damage caused by the financial crisis, it is necessary to pay attention to the systemic risk and its factors.

Change-point detection for expected shortfall in time series

open access: yesJournal of Management Science and Engineering, 2021
Expected shortfall (ES) is a popular risk measure and plays an important role in risk and portfolio management. Recently, change-point detection of risk measures has been attracting much attention in finance.
