【摘要】:資金的凈流入是投資者關(guān)注的重要信息,也是投資者選股考慮的主要因素。定單流是衡量資金凈流入的主要指標(biāo),具有豐富的信息含量,蘊(yùn)含著投資者的買賣信息。本文從投資者期望效用最大化角度,將定單流引入投資組合模型。通過定單流指標(biāo)確定組合權(quán)重,構(gòu)建定單流沖擊下的證券投資最優(yōu)組合模型。實(shí)證分析結(jié)果表明,根據(jù)定單流指標(biāo)確定投資權(quán)重,能取得更好的投資收益。
[Abstract]:The net inflow of funds is the important information of investors' attention and the main factor of investors' stock selection. Order flow is the main index to measure the net inflow of funds. It has rich information content and contains investors' buying and selling information. In this paper, the order flow is introduced into the portfolio model from the perspective of maximizing the expected utility of investors. The optimal portfolio model of securities investment under the impact of order flow is constructed by determining the weight of portfolio through order flow index. The empirical results show that the investment weight can be determined according to the order flow index, and better investment returns can be obtained.
