封闭基金折价是封闭式基金在二级市场上的交易价格低于实际净值的现象。本文利用主成分分析和因子分析的方法,探索影响封闭式基金折价的微观因子。通过建立多元回归模型,对影响封闭式基金的微观因子进行定量分析,并把这些因子分为时间因子,规模因子和价值因子三种。最后,本文提出了减小封闭式基金的折价率的对策建议。 Closed-end fund discount is closed-end funds in the secondary market transaction price is lower than the net real phenomenon. In this paper, principal component analysis and factor analysis methods to explore the impact of closed-end fund discount micro-factors. By establishing a multiple regression model, the micro-factors that affect closed-end funds are quantitatively analyzed, and these factors are classified into three types: time factor, scale factor and value factor. Finally, this paper puts forward countermeasures to reduce the discount rate of closed-end funds.
