We find that after continental European firms begin using an English-language electronic wire service to disseminate company news, they exhibit a stronger initial reaction to earnings surprises, a lower post earnings announcement stock price drift, and an increase in abnormal trading volume near earnings announcements, compared with when they disseminated their news in non-electronic format and in a continental European language. Our results hold for a sub-sample of firms for which the decision to use a wire service was likely exogenous. The effect of wire services on investor attention is due to the format of news (electronic and English-language), not to the increased speed of news transmission."

Analysts exhibit stickiness in their stock recommendations because they face reputational concern in changing such recommendations too often and/or difficulties in processing new information. Using a broad set of corporate events, we find that heterogeneity among the population of analysts causes their response to corporate news to be spread over several months. Long-term drift and return reversal following those events can be predicted at different horizons by the fraction of contrarian recommendations, i.e., recommendations that contradict the initial market reception of the news. Together, our findings highlight the role of analysts’ stickiness in shaping long-term stock price reaction to corporate news."

We investigate whether unrealized AFSGL help predict future earnings and whether analysts and investors incorporate the information conveyed by unrealized AFSGL in a timely manner. We conduct our investigation on a sample of banks because unrealized AFSGL are material in the banking industry. First, we show that unrealized AFSGL are material and help in predicting next period realized AFSGL and future earnings change. Second, we document that financial analysts are slow to react to unrealized AFSGL and update their forecasts after AFSGL are realized in earnings. Third, we find that investors are also slow to react to unrealized AFSGL and do so only after AFSGL are included (realized) in earnings and after financial analysts update their forecasts. We document an annual difference of 5% in future abnormal returns between banks in the top and bottom quintiles of past unrealized AFSGL. A zero-cost trading strategy that relies on public information about unrealized AFSGL generates a sizeable monthly alpha that ranges between 1.8% and 1.9%."

We investigate whether unrealized AFSGL help predict future earnings and whether analysts and investors incorporate the information conveyed by unrealized AFSGL in a timely manner. We conduct our investigation on a sample of banks because unrealized AFSGL are material in the banking industry. First, we show that unrealized AFSGL are material and help in predicting next period realized AFSGL and future earnings change. Second, we document that financial analysts are slow to react to unrealized AFSGL and update their forecasts after AFSGL are realized in earnings. Third, we find that investors are also slow to react to unrealized AFSGL and do so only after AFSGL are included (realized) in earnings and after financial analysts update their forecasts. We document an annual difference of 5% in future abnormal returns between banks in the top and bottom quintiles of past unrealized AFSGL. A zero-cost trading strategy that relies on public information about unrealized AFSGL generates a sizeable monthly alpha that ranges between 1.8% and 1.9%."

Slower-revising analysts tend to change recommendations following corporate news that are harder to interpret by non-stock experts, and our evidence suggests that their investment value derives from their ability to better interpret hard-to-assess information. On average, analysts change recommendations less frequently as their career progresses; however, recommendation speed-style is the dominant predictor of their recommendation value."

"fr" => "This paper examines the communication strategies employed by small cap firms listed on the Alternative Investment Market (AIM) of the London Stock Exchange. These small cap firms have great discretion in choosing their communication channels with investors and evolve in an environment with few information intermediaries. We investigate the use of three communication channels – press releases, conference calls, and social media – specifically surrounding earnings announcements. Our findings indicate that small cap firms utilize these three communication channels infrequently. However, when announcing positive earnings news, small cap firms are more likely to employ these channels, suggesting that firms communicate opportunistically. We find a positive association between the use of communication channels, particularly of social media, and measures of investor attention. Interestingly, while the use of communication channels is associated with positive stock returns surrounding earnings announcements, social media usage prior to earnings announcements is linked to subsequent stock price reversals. These findings provide insights into the communication practices of small cap firms and their implications for investor attention and market efficiency."
