1、电子科技大学博士学位论文基于因素模型的组合投资决策方法研究姓名:马永开申请学位级别:博士专业:管理科学与工程指导教师:唐小我20050620电子科技大学博士学位论文策模型(Roll(1992)、马永开和唐小我(2001)),建立基于基准组合的多因素证券组合投资决策模型,研究了模型的解和模型控制参数值的选取问题。在上述研究基础上,本文尝试将因素模型引入到组合投资管理决策全过程,即同时将因素模型引入战略投资决策阶段、战术投资决策阶段和风险控制阶段,结合目前发达国家金融界兴起的一种组合投资风险管理新技术—风险预算技术,建立基于多因素模型的风险预算方法体系。最后
2、,本文对Shefrin和Statman建立的行为证券组合理论从实用性角度进行了拓展性研究,建立了实用的行为证券组合投资决策模型,并将因素模型引入到行为证券组合投资决策模型中,建立了一种只需建立一个价值空间的行为证券组合投资决策模型。关键词:组合投资管理,单因素模型,多因素模型,基准组合,风险预算,行为证券组合投资理论摘要AbstractAnewtrendindevelopingmodernportfoliomanagementtheoryistoimprovethetransparenceofriskallocation,whichisalsotheco
