ABSTRACT In this paper, we document regularities in trading patterns of individual and institutional investors related to the day of the week. We find a relative increase in trading activity by individuals on Mondays. In addition, there is a tendency for individuals to increase the number of sell transactions relative to buy transactions, which might explain at least part of the weekend effect.
