Abstract
Portfolio optimization plays a significant role in the contemporary financial field. This paper directly analyzes the decision of asset allocation under the situation of multiple assets existence in Chinese financial market. We select five specific companies which have already succeed in the Shenzhen stock exchange and adopt Mean–variance Model to ensure the expected return and adjust the right portfolio to minimize the total investment risk. Then we calculate the minimum risk portfolio and the maximum Sharpe ratio portfolio for a given asset and the maximum expected return portfolio for a given risk and find the minimum risk portfolio for a given return. The result shows that: First, finding the investment portfolio exclusively by the smallest variance is not so practical in the reality. Besides, Vanke has the highest return among the five firm, which is deemed as the most appropriate assets to be selected to invest. The findings may be useful to related investors interested in multiple-asset investment.
