Empirical Analysis of GARCH Effect for Mized Jump of Shanghai Security Indez
Absorbing exchange rate as exogenous disturbance, a mixed GARCH-Jump model is proposed to compare return series fluctuation of Shanghai Composite Index with that of Dow Johns Index. It also incorporates properties of asymmetry, clustering, leptokurtosis and fat-tail of index series fluctuation into an integrated analytic frame of so-called diffusion-jump. Fitness test of GARCH-Jump model proves that abnormality of return series fluctuation of emerging markets can be more effectively explained by it than by single model.
