Abstract
The Chinese stock market is unique in which it is
moved more by individual retail investors than institutional investors. Therefore,
for economic and political stability it is more important to efficiently manage
the risk of the Chinese stock market. We investigate its volatility dynamics
through the GARCH model with three types of heavy-tailed distributions, the
Student’s t, the NIG and the NRIG
distributions. Our results show that estimated parameters for all the three
types of distributions are statistical significant and the NIG distribution has
the best empirical performance in fitting the Chinese stock market index
returns.
