Abstract

We first provide evidence of investor inattention to a very simple and well-known capital gains tax exemption in the Brazilian stock market. We then show that inattentive investors exhibit worse trading performance and stronger trading biases even after controlling for several investor-level variables, such as past trading experience. The evidence is consistent with inattention being one of the explanations for the prevalence of behavioral biases. This paper was accepted by David Sraer, finance. Funding: F. Chague and B.
