讲座内容：

Above (below) consensus earnings forecasts by financial analysts are often considered as good (bad) news in the accounting and finance literature. In this paper, we first document that, in about one third of our sample, earnings surprises and corresponding market price changes are of opposite signs during the announcement period. Using the shorting data from the Regulation SHO pilot program from January 2005 to July 2007 period, we then investigate how short seller behave when earning shocks and corresponding market price responses are of opposite signs. We find shorting intensity is significantly higher for the cases of negative earnings surprises accompanied with positive returns than for the instances of positive earnings surprises associated with negative returns, after carefully controlling other short-selling determinants documented in the literature. The findings are consistent with the notion that short sellers are sophisticated investors who can take advantage of possible misvaluation during the earnings announcement period.
