Predictable time‐series biases in analyst target prices and stock returns
Target prices often draw criticism because of their optimistic nature and lack of substantial investment value. I provide evidence that removing predictable time‐series biases in target prices significantly improves the information content of these estimates. Empirical tests do not support that these benefits stem from market underreaction to predictable biases. Instead, evidence indicates the informativeness of unbiased estimates about priced risk factors beyond common factors. Unbiasing target prices may improve their ability to capture time‐series momentum. Finally, I delve into the methodological facets of the unbiasing procedure, leading to the development of frameworks that possess tangible practical relevance.
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.
