We use the data from BHP company in 1995-2001 and calculate the implied volatility. By comparing the implied volatility calculated from actual option price and the assumed volatility in the model, it is found that Black-Scholes Model does underprice the Out-of-The-Money options and overprice the In-The-Money options because of the wrong assumption on the volatility.

本文选择了澳大利亚BHP公司1995年-2001年其中五年的数据，从实际期权价格中计算得到隐含波动率，并把其与Black-Scholes模型中的假设波动率进行比较，最后可以发现，Black-Scholes模型低估了虚值期权的价格，高估了实值期权的价格，与一般的研究结果恰好相反。

There are many ways to apply the estimated volatility, one of which are volatility trading, trading strategy including pure volatility trading strategy and trend volatility trading strategy.

波动率估计的结果应用途径很多，其中之一便是进行波动率交易，具体的运用方法包含纯波动率交易策略与倾向型波动率交易策略等。

The empirical study in this article finds that all the implied volatility subsumes some information contained of the realized volatility, and the information contain of implied volatility is more than historical volatility.

At last, we continue to analyze the influence which the macroeconomic growth rate has on the volatility of the stock returns. We make the macroeconomic growth rate as an exogenous variable to add to the above iterated weighted volatility model. From the above analysis, we can draw a conclusion that the volatility of the stock returns of Chinese stock markets will strengthen in economic expansion period and weaken in economic recession period.

在此分析前提下，继续深入分析宏观经济增长率对股票市场收益率波动的影响，将宏观经济增长率作为外生杠杆变量加入到上面的迭代加权最小二乘法的条件波动率模型中，结论是我国股票市场收益在经济扩张期波动性减弱，而在衰退期波动性增强。

The volatility of Chinese stock market is investigated using the dynamic version of stochastic volatility model, and Bayesian analysis based on MCMC is introduced to improve the parameters estimation in stochastic volatility model.
