Abstract

The objective of this article is to reveal the evolution of the investment portfolio establishment approach. The evolution from the diversification effect, whose primary goal is to minimize risk, to the use of the Markowitz model to find the portfolio with the highest return per risk, to finally taking capital constraints into account, so that investors can find the best portfolio under the constraints of limited capital. We select three assets with low correlation, named Putnminc, Fidel and Keystne, then collecting and analyzing their monthly return values to illustrate the evolution process. Simultaneously, the impact of risk-free assets is taken into consideration.
