This study documents a six-fold increase in short-term return reversals during earnings announcements relative to non-announcement periods. Following prior research, we use reversals as a proxy for expected returns market makers demand for providing liquidity. Our findings highlight significant time-series variation in the magnitude of short-term return reversals and suggest that market makers demand higher expected returns prior to earnings announcements because of increased inventory risks that stem from holding net positions through the release of anticipated earnings news. Collectively, our findings suggest that uncertainty regarding anticipated information events elicits predictable increases in the compensation demanded for providing liquidity and that these increases significantly affect the dynamics and information content of market prices.

Executives with poor prior performance may be inclined to take excessive risk in the hope of meeting performance targets, in which case a compensation contract featuring severance pay can be optimal. While prior work has shown that severance can induce managers to take positive NPV risks, we show that it can also keep them from taking negative NPV risks. We show that severance should be contingent on results: complete failure should nullify any payments. We also show that mandating a firm size that is larger than first-best, while costly, can help screen for good managers.
