Abstract

This paper investigates the combined effect of financial attention and financial literacy on investors’ performance. Our empirical analysis, based on a large and unique broker- age dataset, suggests that highly literate investors benefit by paying financial attention, whereas attention can be counterproductive for investors with low financial literacy. More- over, when investors, either highly or lowly literate, are overconfident about their financial literacy, the impact of financial attention on their performance is reinforced.

"Every cloud has a silver lining: the Good Side of Overconfidence"

Abstract

This paper investigates whether investors who claim trading experience in complex financial products exhibit greater overconfidence and higher financial literacy than investors who declare to have any trading experience in complex instruments. Using MiFID test scores and a unique brokerage dataset, we rank investors' financial literacy and measure overconfidence as the difference between subjective and objective financial literacy, and through a switching regression design, we find highly literate investors perform better if they are overconfident.
