abstract
We investigate the relation between the transparency of financial statements and the distribution of stock returns. Using earnings management as a measure of opacity, we find that opacity is associated with higher R2s, indicating less revelation of firm-specific information. Moreover, opaque firms are more prone to stock price crashes, consistent with the prediction of the Jin and Myers [2006. R2 around the world: new theory and new tests. Journal of Financial Economics 79, 257–292] model. However, these relations seem to have dissipated since the passage of the Sarbanes-Oxley Act, suggesting that earnings management has decreased or that firms can hide less information in the new regulatory environment. & 2009 Published by Elsevier B.V.

1. Introduction Financial economists and accountants have long viewed stock price changes as tied to new information about firms’ prospects. However, Roll (1988) finds that only a relatively small portion of price movements can be explained by contemporaneous public news and speculates that traders acting on nonpublic firm-specific information could drive returns. These results have stimulated considerable interest in the relation between information and stock price dynamics and, in particular, between the R2 from a modified index-model regression and the revelation of firm-specific news. For example, Morck, Yeung, and
