Using Bloomberg’s daily Twitter Sentiment data for S&P500 firms, we show that Twitter information reduces forecast optimism and improves forecast accuracy of sell-side equity analysts. Negative Twitter information is more influential, and this effect is distinct from the impact of news. Using...

Amendments to NASD Rule 2711 and NYSE Rule 472, enacted in May 2002, mandate that sell-side analysts disclose the distribution of their security recommendations by category of buy, hold, and sell. This regulation enhances the transparency of analysts' information and mitigates the...

We examine whether actively managed equity mutual funds trade on localised information events - syndicated loan covenant violations and changes in bank loan and entity ratings. Local investors achieve positive abnormal stock returns only around covenant violation periods rather than changes in...

Using data from the Stockholm Stock Exchange we study the value added by (as distinct from the abnormal returns to) analysts' recommendations. Recommending brokers' clients trade profitably around positive recommendations at the expense of other brokers' clients. Significant profits come from...
