Additionally, this paper analyses if these two measures have the same impact on multinational companies and local companies. By using CAPM and descriptive statistical analysis, the researchers find that economic stimulus is effective in short term but controlling the spread of pandemic plays the key part in long-term economic growth, international trades make a difference in reducing risk during COVID-19. Finally, to understand is the impact of investor sentiment on stock prices the reason for these two responses to changes in stock returns, Fama-French three factor with sentiment factor added is used to explore the relationship between investor sentiment and stock returns.
