摘要
针对证券组合投资中存在的随机性,在投资收益达到一定水平下,综合考虑收益率的平均绝对离差和信息熵作为投资组合的风险度量,建立了数学模型。并用该模型进行了实例分析,结果表明,在投资收益不变的前提下,多方面的考虑风险,使得投资方案更安全。
In the view of randomness exist in portfolio, the mathematical model is established absolute deviation and information entropy to measure portfolio risk where return on investment by using average is at a specified level. The results of example analysis by the model show that multidimensional consideration of risks makes investment proposals safer.
