Abstract

Portfolio theory provides an important conceptual foundation and a comprehensive set of analysis systems for portfolio creation and analysis, and it has a significant impact on modern investment management practice. The rationality of portfolio theory on decentralized investing is a critical theoretical foundation for the fund management industry’s existence. Furthermore, Markowitz’s notion of an “effective portfolio” redirected managers’ focus away from individual stocks and toward constructing successful portfolios. Markowitz’s portfolio theory has shown to be successful in reality regarding the optimal allocation of main asset types in a portfolio. This paper takes the investment portfolio as the theoretical entry point. In-depth research from concept, domestic and foreign research review, and application model (CAPM, Fama-French 5 factor model, and q-factor model). And this paper tried to explore the predictive power of asset pricing under the impact of the COVID-19 outbreak. On the one hand, the thorough analysis and summary of portfolio theory. On the other hand, it provides a theoretical basis for relevant portfolio practice.
