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.

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.
