Using a large database of Japanese analysts’ rating information over the period 2000-2010, we examine short term market reactions to the announcement. We find a significant market reaction to the information contained in the analysts’ rating. Particularly, the market reacts sensitively to the rating changes rather than the rating itself. We also examine whether investors are able to achieve a positive net return by taking advantage of the abnormal market reaction to the analysts’ signal by constructing a dynamic calendar time equity long-short portfolio. Results indicate that investors are able to capture some abnormal profit trading on such signals, however, large size investment based on the same strategy becomes implausible due to the transaction costs.
