Discussion of “Investor Sophistication and the Mispricing of Accruals”

Collins et al. (2003, this issue) empirically investigate the relation between accruals mispricing and institutional ownership (IO), a proxy for investor sophistication. Their results show that accruals mispricing and IO are negatively correlated; less IO, more accruals mispricing. The authors attribute this differential in accruals mispricing to institutions' superior ability to price accruals either due to superior analytical ability or due to greater access to private information. While the research question is intriguing, a number of methodological limitations may limit the reliability and generality of the findings. In this paper, I discuss these limitations and offer ways of overcoming them, as well as identify a future research avenue in the area of mispricing.
