Abstract
This paper examines the information content of Form 4filings under the stricter disclosure regulations introduced by the Sarbanes-Oxley Act (SOX). Abnormal returns around filing have been used to measure information content. Insider ranking was found to be the most influential variable explaining the information content of the filing. A comparison study between pre- and post-SOX for both purchase and sale sample has provided evidence that information content of filing has improved. This is the first study provide evidence that information content of form 4 filings have improved after the recent credit crunch.
