Reversal evidence from investor sentiment in international stock markets
This research investigates the effect of sentiment on the time-series and cross-section of mean, variance and correlation of asset returns to examine how investor sentiment creates predictable variations in financial markets. Based on the method proposed by Baker and Wurgler (2007, Investor sentiment in the stock market, Journal of Economic Perspectives 21, 129-152), we build composite sentiment indexes with a focus on international markets. Our time-series results show that optimistic (pessimistic) sentiment leads to overpricing (underpricing) and that variance and correlation of asset returns increase when investors are pessimistic. Our cross- section results suggest that these effects tend to become more pronounced for stocks with more exposure to sentiment or the market.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
