Martin Utrera, Alberto (2018) Maximum Mispricing on Announcement Days. Working Paper. UNSPECIFIED.
Full text not available from this repository.Abstract
I study the role of macroeconomic announcements in the multidimensional challenge posed by Cochrane (2011). Recent work argues that market betas explain average returns well on announcement days, however I document that the exposure to a multi-signal factor contributes to explain the cross-section on those days. A long-short strategy exploiting these exposures can improve the market Sharpe ratio by 30% on announcement days. I argue that macroeconomic announcements can exacerbate CAPM-mispricing of certain stocks, and its large economic significance can be illustrated through simple trading rules. A parsimonious rational expectations model with multiple signals about fundamentals can reconcile these results.
