We examine the relative efficiency of whisperers’ and analysts’ forecasts of one-quarter-ahead earnings per share (EPS) and identify commonalities and differences in their use of fundamentals to forecast earnings. Results suggest that (a) fundamentals that focus on sales and cost of sales are relevant in explaining one-quarter-ahead EPS changes; (b) whisperers focus on cash flow fundamentals and accrual-based earnings measures in their one-quarter-ahead forecasts, whereas analysts focus on only cash flow fundamentals; and (c) although neither analysts nor whisperers fully incorporate information contained in fundamentals and accrual-based earnings measures in their forecasts, whisperers’ earnings forecast model (forecast errors model) exhibits higher (lower) explanatory power than that of analysts. We also examine robustness of our results by reestimating the models using a two-way random-effects panel data estimator. Although our conclusions remain the same, more statistically significant fundamentals emerge in panel regression results. Evidence presented in this article is consistent with (a) whisperers being different from analysts and (b) whisper forecasts containing unique incremental information beyond that of analysts’ forecasts. Market participants may want to consider using both forecasts when making investment decisions.
