Sažetak
COVID-19 has slowed the growth of, the global economy, which has
certain practical significance. Consequently, this study seeks to analyze
the investment opportunities in the medical sector before and
after the COVID-19 outbreak. In this study, the Markowitz mean–variance
(MV) model, capital asset pricing model (CAPM), and correlation
models are constructed based on the principle of Markowitz
MV and correlation analysis. Simultaneously, statistical analysis is
used to verify the analysis, and the MATLAB statistical tool is used
to build the model. The results show that the actual expected yield
of China’s medical sector is significantly higher than that calculated
by the CAPM before and after the pandemic, and that the investment
value of the medical sector is undervalued by the market.
From the perspective of risk, China’s medical sector has a stable systemic
risk premium. Based on the above analysis, when building
investment portfolios in the post-pandemic era, investors should
appropriately allocate stocks in the medical and pharmaceutical sectors
to improve the portfolio income and diversify the investment
risk.
