摘要

本研究利用改进的CSAD模型来检测COVID-19流行之前和期间发展中市场的羊群行为。从2019年7月到2021年6月，我们评估了印度证券交易所12个行业指数的结果。我们发现，在新冠肺炎疫情爆发之前，出现了相当多的有意羊群行为，但在疫情爆发后，出现了反羊群行为。2019冠状病毒病爆发后的周一，放牧活动有所加强，但一周中的其他几天则有所减少。这项研究表明，2019冠状病毒病大流行可能削弱了投资者区分信号的能力，导致他们对行业指数的投资随机关联，而不是区分信号以跟随市场领导者获得更大的回报。

Wednesdays obtain herd immunity? Examining the effect of the day of the week on the NSE sectoral market during COVID-19

ABSTRACT A modified CSAD model is utilised in this research to detect herding in the developing market prior to and during the COVID-19 epidemic. From July 2019 through June 2021, we evaluate the outcomes of the NSE's twelve sectoral indices. We find considerable intentional herding before to the outbreak of COVID-19, but anti-herding after the pandemic on Wednesday. Herding is enhanced on Mondays after COVID-19 outbreak but decreases on the other days of the week. This study suggests that the COVID-19 pandemic may have impaired investors’ capacity to discriminate between signals, leading their investments in sectoral indices to be connected at random rather than distinguishing between signals to follow the market leader for larger returns.
