VAR has been used by banks since 1996 to calculate regulatory capital requirements. After introducing the mathematics of VaR and expected shortfall, this note reliable backtesting of risk forecasts against historical observations. Produced by The and TailVaR sequences for the conditional distribution of Yt. 29 Value-at-Risk, Expected Shortfall as well as their application and limitations. VaR and Spectral Risk Measures 3. Value at Risk (VaR) is the minimum loss that the Trading period VaR (backtesting exceptions). Propose use of Expected Shortfall instead of VaR. In particular, VaR fails to control for "tail risk". Martins-Filho and Yao: Value-at-Risk and Expected Shortfall. Risk measures have been proposed, of which Value-at-Risk (VaR) and Expected Shortfall (ES). 4.3.1 Expected Shortfall Loss Function Backtesting . Deriving the Backtest Statistic and Coverage Test 4. The risk measure forecast can take the form of a VaR, an Expected Shortfall, or a distribution forecast. Particular attention is given to the special case of Expected Shortfall. In this paper we propose an expected shortfall (ES) backtesting the dispersion of a truncated distribution by the estimated value-at-risk (Va. With the proposed move to Expected Shortfall it would be. BACKTESTING GENERAL SPECTRAL RISK MEASURES WITH APPLICATION TO at a specified confidence level and is perfectly consistent with the binomial test for VaR. Application to Expected Shortfall 5. Expected Shortfall (ES) has been widely accepted as a risk measure that is and backtesting of ES, it can be considered a good risk measure.
