Estimating Value-at-Risk for Chinese stock market by switching regime arch model

This paper proposes a method of estimating Value at Risk (VaR) based on the assumption that the financial returns follow a switching regime ARCH model. We use the simple switching-regime model, the traditional GARCH(1,1) model and the switching-regime ARCH model to do some empirical analysis and to calculate the VaR values under different confidence levels for Shanghai and Shenzhen Stock Index. The calculated VaR values are compared. The results of back-testing and the Proportion of Failure test show the VaR values calculated by the switching-regime ARCH model are preferred to other methods.Engineering, MultidisciplinaryOperations Research & Management ScienceMathematics, Interdisciplinary ApplicationsSCI(E)SSCI0ARTICLE2145-163
