The impact of litigation risk on the strategic timing of management earnings forecasts

This paper examines whether managers strategically time their earnings forecasts (MEFs) as litigation risk increases. We find as litigation risk increases, the propensity to release a delayed forecast until after the market is closed (AMC) or a Friday decreases but not proportionally more for bad news than for good news. How costly this behaviour is to investors is questionable as share price returns do not reveal any under‐reaction to strategically timed bad news MEF released AMC. We also find evidence consistent with managers timing their MEFs during a natural no‐trading period to better disseminate information.     

上市公司业绩预告偏差对股价崩盘风险的影响—基于内部控制的视角

利用我国A股2012-2018年上市公司数据,探讨上市公司业绩预告偏差与偏离方向如何影响股价崩盘风险,以及内部控制质量对两者的调节作用。研究发现:公司业绩预告偏差与股价崩盘风险显著正相关;与悲观偏差相比,业绩预告乐观偏差才会加剧股价崩盘风险,高质量的内部控制能够缓解业绩预告乐观偏差加剧的股价崩盘风险。进一步研究发现,当上市公司业绩预告需要强制披露、披露越及时及披露坏消息时,内部控制质量的调节作用更加显著。由此证明,高质量内部控制在缓解因业绩预告乐观偏差加剧的股价崩盘风险中发挥重要作用。     

The effect of the summer doldrums on the market reaction to earnings announcements

Hong and Yu (2009) document a significant decrease in trading volume and returns during the summer months. Given the tendency of noise traders to buy shares following both positive and negative earnings surprises (Lee, 1992), we hypothesize that reduced trading activity by noise-traders results in less of an earnings announcement premium during the summer. Consistent with our hypothesis, we find lower abnormal returns surrounding summer earnings announcements compared to non-summer announcements. We also find lower abnormal returns in the ten days prior to the announcement, consistent with less front-running by sophisticated investors. Finally, we show that these summer effects are stronger in recent years characterized by more online trading and greater noise trader participation.     

The effect of SFAS 131 on the stock market’s ability to predict industry‐wide and firm‐specific components of future earnings

This study examines the impact of SFAS 131 on the extent to which stock prices incorporate industry‐wide and firm‐specific components of future earnings. By decomposing earnings into industry‐wide and firm‐specific components, this paper finds that the firms that aggregated segments under the old rule experience significant acceleration in the incorporation of future earnings into current stock prices upon adoption of SFAS 131. However, the acceleration of future earnings is mostly driven by the improved incorporation of industry‐wide components of future earnings, which indicates the market’s ability to predict firm‐specific components is not significantly changed. Supplemental analysis suggests that the reduced geographic earnings information is one possible reason for lack of improvement in incorporating firm‐specific earnings into price.
