摘要: 传统历史模拟法(THS,Tranditional Historical Simulation)和滤波历史模拟法(FHS,Filtered Historical Simulation)是国际商业银行使用最多的VaR预测方法。首先,论文在已有研究成果的基础上,构造了BHW(Bootstraped Hull and White)历史模拟法;然后,以国内黄金交易数据为样本,采用6种严谨的后验分析(Backtesting analysis)方法,对BHW方法及几种主流历史模拟法、GARCH模型方法的VaR预测精确性进行了实证分析。论文的主要结论包括:(1)综合论文所采用的几种金融风险测度方法来看,BHW方法表现出了相对较好的精确性,而实务界中广泛使用的THS方法则表现出了最差的精确性;(2)不同的历史模拟法受样本规模因素影响的程度显著不同,例如THS方法和HW方法均不同程度的受到了样本规模因素影响;(3)总体来看,BHW方法表现出了相对较好的风险预测精确性,可以作为测度黄金市场风险的选择之一。

Abstract: Traditional Historical Simulation and Filtered Historical Simulation are the most used risk measurements among international commercial banks. Another filtered historical simulation approach——BHW is presented in this paper, which is constructed by Hull and White (1998) and bootstrap methods. Then the spot trading of gold price is taken as samples, and the accuracy of the BHW method and other popular methods, such as traditional historical simulation methods, BRW methods, Hull and White(1998) methods and parametrical GARCH methods are backtested. Since Dumitrescu et al. (2012) pointed out that there's none backtesting method have absolute advantage on others, and suggest that take more backtesting methods as possible, six different methods are taken. The conclusions include:(1) Compared with the other 4 popular risk measurement methods, BHW methods shows relative better accuracy; (2) In the small sample case (125 days), the advantage of BHW are significantly better than other methods, when the sample size become larger (250 days), HW, BHW and GARCH models all show relative better accuracy, and the HW approach is slightly better than other methods; (3) the accuracy of different historical simualtion methods are influenced by rolling sample size differently.
