COVID-19 Vaccination Effect on Stock Market and Death Rate in India

COVID-19 Government restriction policy, COVID-19 vaccination and stock markets: Evidence from a global perspective

We use the COVID-19 stringency index to investigate the relationship among COVID-19 government restriction policy, COVID-19 vaccination and stock markets. We find that the impact of the change rate of COVID-19 stringency index on stock returns turns from significant in the pre-vaccination period to insignificant in the post-vaccination period. Bad news from COVID-19 restriction policy cause more stock volatilities than good news. The advent of COVID-19 vaccination weakens the linkage of COVID-19 stringency index and stock market, while COVID-19 stringency index only plays a partially mediate role in the correlation between COVID-19 cumulative vaccination rate and stock market performance.

Does US full vaccination against COVID-19 immunize correspondingly S&P500 index: Evidence from the NARDL approach

This study analyzes the impact of COVID-19 full vaccination shocks on the US stock market in the period January 14, 2021- August 20, 2021. Using the Nonlinear Autoregressive Distributed Lag model, we find that the positive and negative COVID-19 full vaccination growth shocks have a positive and symmetrical impact on the US stock market over the long run. Additionally, the short-run findings provide that the US stock market reacts negatively with delay to the positive and negative COVID-19 full vaccination growth shocks. The study findings provide good insights that COVID-19 full vaccination immunizes accordingly to the S&P 500 index in the long run. The study results indicate that the impact of positive and negative COVID-19 full vaccination growth shocks on the stock market in the short run differs from that in the long run. This research bears important implications: governments should implement preventive measures with vaccination to recover the stock market. Policy makers ought to urge adopting policy measures to reduce panic and boost investor confidence during economic and health crises.
