The Information Content of Sec Filings and Information Environment: A Variance Decomposition Analysis
Posted: 26 Mar 2006
Using the Vuolteenaho (2002) variance decomposition methodology, this study assesses the relative value relevance of cash flow, accrual (earnings) and expected return news on SEC and preliminary earnings filing dates, as measured by their contribution to the volatility of unexpected returns. Cash flow news is found to be more value relevant than accrual news. Although expected return (risk) news is the least value relevant, it is significantly correlated with changes in betas and returns at the preliminary and SEC filing dates, indicating association with changes in firm risk and discount rates. This study also documents that these informational components contain less (more) value relevant information at the SEC filing date for firms with a higher proportion of long-term (transient momentum) sophisticated investors after controlling for other dimensions of the information environment.
