Investment diversification is one of the important means for investors to reduce risks. Therefore, based on the portfolio theory, this thesis studies the construction and optimization methods of investment portfolios to reduce investment risks.
This paper first introduces the history and research significance of portfolio theory, and expounds the relevant concepts of asset pricing model, efficient frontier theory, capital asset pricing model and other related to portfolio theory.
Secondly, this paper discusses the methods and techniques of portfolio construction, including mean-variance model, minimum variance combination, efficient frontier combination and other methods. Through simulation experiments and data analysis, this paper proves the ability and effectiveness of portfolio construction and optimization.
Finally, this paper explores the effect of different portfolio strategies in different market environments and how to adjust the portfolio to adapt to different market conditions through empirical analysis. On this basis, it is proposed that investors should focus on information collection and analysis, choose suitable portfolio strategies to reduce investment risks.
Keywords: portfolio theory, mean-variance model, minimum variance combination, efficient frontier combination, asset pricing model, market environment, investment risk.
