摘要

我们发现，2019冠状病毒病大流行增加(降低)了股票回报对市场范围(特定公司)新闻的敏感性，这与回报逆转(延迟反应)有关。这些结果与疫情爆发后投资者关注有限、对宏观(微观)信息关注增加(减少)的情况一致。对于总部设在流行病中心的公司和较大的股票来说，当流行病传播程度较高时，对好消息的偏见反应比坏消息更多。我们还发现，在大流行期间，与市场范围(特定公司)新闻相关的交易、信息流和价格效率更高(更低)不平衡。

Limited investor attention and biased reactions to information: Evidence from the COVID-19 pandemic

We find that the COVID-19 pandemic increases (decreases) stock return sensitivity to market-wide (firm-specific) news, which is associated with return reversals (delayed reactions). These results are consistent with limited investor attention and investors paying heightened (reduced) attention to macro (micro) information after the outbreak. There are more biased reactions when the epidemic spread is higher, to good news than bad news, for firms headquartered in pandemic epicenters, and for larger stocks. We also find higher (lower) imbalanced trading, information flow, and price efficiency associated with market-wide (firm-specific) news during the pandemic.
