Table 2.

The pandemic and stock return responses to news.

This table presents the regression results of current and future stock returns for the impact of the pandemic on stock return responses to news. In Panel A, the dependent variable in the regression is the stock close-to-close returns of day $t$, $Retur{n}_{i,t}$. In Panel B, the dependent variable in the regression is the future stock returns over the next ten days, $Retur{n}_{i,(t+1,t+10)}$. $MkNew{s}_t$ and $FmNew{s}_{i,t}$ indicate market-wide and firm-specific news on day $t$, respectively. In both panels, columns (1) and (2) present the results for the full period from January 2019 to December 2020, and $Outbrea{k}_t$ is a dummy variable being zero during January 1, 2019 through February 28, 2020 and unity from February 29, 2020 onwards. Columns (3) and (4) present the results for the post-outbreak period from February 29 to December 31, 2020, and $dSprea{d}_t$ is the detrended spread of the COVID-19 infection on day $t$. $\Delta VI{X}_t$ refers to the change in market volatility index. Stock fixed effects are included in all regressions, together with $\Delta VI{X}_t$ and five lags of stock returns. Five lags of market returns are also included in the regressions for the even columns. Standard errors are clustered at the stock level. The t-statistics are reported in parentheses. ***, **, and * indicate significance at the 1%, 5%, and 10% levels, respectively.
