Predicting Returns with Managerial Decision Variables: Is There a Small-Sample Bias?
Posted: 22 Feb 2006 Last revised: 12 Aug 2008
Many studies find that aggregate managerial decision variables, such as aggregate equity issuance, predict stock or bond market returns. Recent research argues that these findings may be driven by an aggregate time-series version of Schultzs (2003) pseudo market-timing bias. Using standard simulation techniques, we find that the bias is much too small to account for the observed predictive power of the equity share in new issues, corporate investment plans, insider trading, dividend initiations, or the maturity of corporate debt issues.
