Distribution prediction provides a complete description of forecasting uncertainty, which is of great significance to risk management. In this paper, the parametric method based on GARCH and the nonparametric method based on EWMA are both employed to model the conditional distributions of the SHCI and SZCI returns in Chinese stock market. As a result, the nonparametric method is better from the perspective of quantile evaluation. Furthermore, a simulated trading strategy based on time-varying quantiles is designed to analyze the trading yields of different levels of risk aversion. For the whole sample, compared with the buy-and-hold, SHCI has a higher profit in lower risk aversion and SZCI has higher profit only in a very narrow range when compared with the buy-and-hold strategy. In addition, the impact of IF:CSI 300 is considered. For the sub sample, before the emergence of IF:CSI 300, only a few investors with high risk aversion are able to achieve higher earnings from SHCI and there is hardly any opportunity for higher profit from SZCI. However, for the sub sample after the emergence of IF:CSI 300, many risk lovers and risk neutral investors have the opportunity to gain more profit than under the buy-and-hold strategy, both for SHCI and SZCI. The aforementioned conclusions imply that IF:CSI 300 may enhance Chinese stock market activity and liquidity and create more opportunities for investors who are not risk averse.
