We find that the degree of expected idiosyncratic skewness in seasoned equity issuers’ stock returns is an important determinant of flotation costs and subsequent abnormal stock performance. High skewness issuers incur significantly greater offer price discounts, particularly when institutional share allocation is largest, pay higher gross underwriting spreads, and exhibit poorer stock performance in the three years after issuance, all compared to low skewness issuers. These results suggest that skewness-induced overpricing increases the flotation costs of seasoned equity offers and leads to poor subsequent stock performance.

Recent research finds that investors, broadly defined, react to the linguistic tone of quarterly earnings conference calls; there is a positive relation between firms' stock returns and call tone (a measure of “sentiment” related word tabulations). However, this type of soft information can be subtle, context-specific, and difficult to interpret. Moreover, the literature suggests cross-sectional variation in information processing skills among investors. Thus, we test whether sophisticated investors interpret earnings conference call tone differently than investors at large by examining short selling activity and its relation to earnings conference call tone. We find that short sellers target firms with simultaneous high earnings surprise and abnormally high management tone. The combination of positive earnings surprise and unusually positive tone strengthens short sellers' return predictability. This result indicates that short sellers interpret revealed “inflated” call language by managers more completely than naïve investors. The incomplete stock price reaction by naïve investors due to the lack of reliability that they place on this soft information results in overpricing of the stock. However, it also suggests that managers are unable to maintain prolonged overvaluation of their stock by striking an overly optimistic posture in the interactive conference call disclosure forum since short sellers' trades provide additional price discovery.
