- W2408610726 abstract "Financial market investors use Internet searches for information acquisition about corporate announcements. This study examines the relation between Internet search volume for firm earnings information and post-earnings announcement drift (PEAD). Our first finding is that Google search volume index (SVI), a measure of Internet search volume, is associated with higher information uncertainty of firms with impending earnings announcements. Secondly, we find evidence that Google SVI does not predict analyst forecast based earnings surprises, but does predict stock market reaction to earnings surprises. These results support the argument that Google SVI reflects information searches by public or uniformed investors. We also find that higher Google SVI appears to reduce PEAD by improving the flow of information and reducing information asymmetries to uninformed investors, thus increasing market efficiency. Google SVI mitigates PEAD up to 40 days after the announcement. Overall, our findings suggest that uninformed investors can reduce the post-earnings announcement returns anomaly and information asymmetries through Internet searches." @default.
