Abstract: Purpose - The aim of this paper is to investigate the impact of voluntary disclosure on information asymmetry between investors and the average information content of subsequent the earnings announcement. Design/methodology/approach - The authors use empirical methodology relying on multiple regression analyses. The authors estimate models of trading volume and stock returns around the earnings’ release date as a function of voluntary disclosures, measured using information in the 8-K statements. Findings - Voluntary disclosures prior to the earnings release date increase trading volume related to stock returns. In addition, voluntary disclosures also reduce stock price movement around that date. Research limitations/implications - The results indicate that voluntary disclosures increase trading volume related to stock returns around the earnings release date. Such increases indicate increased differential precision among investors, demonstrating that voluntary disclosures increase differences in opinion among investors. The reduced stock price movement around the earnings release date also show that voluntary disclosures reduce the information content of earnings. One limitation is that the measure of voluntary disclosures does not consider the variation in the information content of individual disclosures. Practical implications - Firms who make voluntary disclosures will need to carefully consider how to structure such releases to minimize asymmetry between investors. Investors should pay greater attention to finding out, and interpreting, voluntary disclosures by firms. Social implications - Regulators have previously expressed concern about leveling the playing field between more and less informed investors. The results showing increased differences in information as a result of voluntary disclosures provide valuable insights as regulators debate the balance of mandated and voluntary disclosure. Originality/value - This is the first study to investigate the effect of voluntary disclosures on information asymmetry among investors using trading volume and, consequently, the first to find increased differences among investors that result from those voluntary disclosures. The paper is also the first to use a direct measure of voluntary disclosure developed by Cooperet al.to demonstrate the negative relation between voluntary disclosure and the average informativeness of earnings announcements.
