Establishment and application of the portfolio model based on introduction of the risk-aversion coefficient
Zhou Weiguang · Journal of Hefei University of Technology · 2007
The risk-aversion coefficient is introduced into the portfolio model which is based on Markowitz classic portfolio theory,and the binary coding based accelerating genetic algorithm is applied to the calculation in which both the expected rate of return and the risk rate are random so that different effects of the risks and benefits under different investment portfolio strategies are reflected.Different investors with different risk-aversion coefficients may choose different investment portfolio strategies so as to achieve the maximum benefit.
