模糊投资组合是不确定性理论研究的重要领域.然而,由于人的理性局限性,投资者在决策的过程中,可能不是追求理性的效用最大化,而是追求心理满意度的最大化;在金融市场中,投资者不仅面临市场风险,也需要承担由自身因素产生的背景风险.因此,提出了一个考虑背景风险等因素的最大期望满意度模型,该模型的目标是最大化投资组合收益与最小收益证券的差值;最后,以上海证券交易所180指数的十支证券构成的的投资组合为例,分析了此模型在分散投资风险与增加满意度方面的有效性.
However, due to the rational limitation of human, investors may not maximize the utility of pursuing rationality but pursue the maximization of psychological satisfaction in the process of decision-making. In the process of decision-making, In the financial market, investors not only face the market risk, but also bear the background risk caused by their own factors.Therefore, we propose a maximum expectation satisfaction model considering the background risk and other factors, the goal of this model is to maximize the return on investment and Finally, taking the portfolio composed of ten securities of SSE 180 Index as an example, this paper analyzes the effectiveness of this model in diversifying investment risks and increasing satisfaction.
