International Journal of Finance &Economics, EarlyView.ABSTRACT This paper studies herding and anti‐herding behaviour in three European stock markets before and during the Covid‐19 pandemic by employing both static and dynamic analysis. We examine four different questions related to herding behaviour: (i) Did herding behaviour increase during the pandemic? (ii) Does herding behaviour respond differently in
