Review of Pacific Basin Financial Markets and Policies
This study addresses the impact of firm- and time-specific attributes on the accuracy of composite forecasts of annual earnings, constructed as weighted averages of annual earnings forecasts obtained from three sources: time-series, price-based, and analysts’ forecasts. Separate evaluations are provided for smaller and larger firms, and for firms with relatively lower and higher analysts’ coverage. In addition, results are developed separately for time periods pre-dating and following the implementation of Regulation Fair Disclosure (FD). Our results using a pooled sample provide directional support for the use of composite forecasts as earnings expectations. The ensuing analyses within the size and analysts’ coverage partitions of the sample show that the forecast errors for smaller and lightly-covered firms exceed those for the larger and heavily-covered firms by factors of three or four times. Analyses within partitions for time periods before and after the Regulation FD indicate that the relative accuracy of the composite forecasts is time-specific. In the earlier time-period preceding the implementation of Regulation FD, composite forecasts significantly outperform each of the three individual forecast sources used in their construction. Moreover, the extent of improvement in accuracy of composite forecasts is significantly higher for the smaller and lightly-covered firms in the Pre-FD period. Collectively, these results suggest that the predictive accuracy of composite forecasts of annual earnings is contextual.
