Abstract
This paper aims to forecast the monthly volatility of Chinese stock market by using various GARCH models. We also examine the performance of these GARCH models by comparing the predicted monthly volatility to a proxy of actual monthly volatility calculated using daily data. The evaluation result shows that the GARCH-in-mean model is slightly superior to GARCH model and TGARCH model in term of the ability to deliver “accurate” volatility forecast. But EGARCH model seems a lousy approach in our case. We also construct the upper and lower bound of the predicted volatility for GARCH, TGARCH and GARCH-in-mean models. All of these three models seem to be able to create a reasonable range of the predicted volatility. But GARCH and GARCH-in-mean models are better than TGARCH model in this respect. An interesting by-product is that good news generates greater shocks to the market than bad news, which is quite contrary to the widely accepted view that bad news usually creates more volatility to the market than good news.
