摘要 标准 Va R方法的假设条件与实际数据之间存在较大的差距 ,而差距是必严重影响 Va R方法的实际应用效果 .为此 ,本文从实际数据的基本特征出发 ,讨论了 Va R方法在尖峰、胖尾分布中的计算公式 ,并使用该计算公式对我国证券市场的实际数据进行了实证分析 .分析结果表明 ,推广的 Va R计算方法对证券市场风险预警有更可靠的揭示作用 . the criteria VaR means hypothesis condition have a lot of different from actual data, the difference certainly impact VaR means effect for the factual applying. For this reason,this paper base actual data of the essence characteristic, to discuss calculate formula VaR means in the the aiguille and fat tail branch, and make use of the calculate formula to carry out demonstration analysis for the stock market. The analytic consequence show spread VaR calculate formula means for the negotiable securities risk indicate having credible reveal affect.
