The Information Content of SEC Filings and Information Environment: A Variance Decomposition Analysis

Abstract

Using the Vuolteenaho (2002) variance decomposition methodology, this study assesses the relative value relevance of cash flow, accrual, and expected return news on SEC and preliminary earnings filing dates, as measured by their contribution to the volatility ofunexpectedreturns. Cash flow news is found to be more valuerelevant than accrual news. Although expected return (risk) news is the least valuerelevant, it is significantly correlated withchangesin 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 (short‐term) sophisticated investors after controlling for other dimensions of the information environment.
