Behavioral Biases in Financial News and Earnings Expectations
Summary
This note recommends two research papers on behavioral finance and equity anomalies. The first examines how journalists’ experience, education, and industry knowledge relate to the accuracy of merger news when rumors circulate. It reports that vague wording and references to well-known companies are associated with less accurate coverage, while investors’ incomplete assessment of news can contribute to an initial target-stock overreaction followed by a reversal.
The second paper models how sticky expectations may help explain anomalies linked to earnings measures and the sources of alpha. The note says its framework and empirical approach may inform research using consensus forecasts, while cautioning that findings from U.S. markets may not transfer directly to Chinese equities. The document provides only brief summaries of the papers; it does not include their underlying data, model specifications, or detailed empirical results, so readers would need the original studies to assess the evidence and applicability.
