Delayed Security Price Adjustments to Analysts' Forecasts of Annual Earnings


Source: Elgers, Lo & Pfeiffer (2001) · The Accounting Review · DOI: 10.2308/accr.2001.76.4.613


TL;DR


Prices weight analysts' early-in-the-year earnings forecasts less than the historical forecast-realization relation justifies — i.e., the market underreacts to forecasts. Long the top decile and short the bottom decile of cross-sectional analyst forecasts (scaled) generates significant hedge returns as prices later catch up to the forecast information.


What anomaly it documents


  • Predictor: scaled early-year analyst earnings forecasts (relative to price).
  • Direction: positive — high forecasted-earnings firms (underweighted by the market) outperform.
  • Shape: monotone hedge spread; drift as prices catch up to forecasts.
  • OSAP predictor: sfe.

  • How to construct it


  • Sorting variable: consensus analyst earnings forecast scaled by price, early in the year.
  • Universe: firms with analyst coverage.
  • Portfolio formation: decile sorts on the scaled forecast.
  • Long / short: long top decile, short bottom decile.
  • Weighting: equal-weighted.
  • Rebalancing: annual.

  • Evidence and replication

    Why it might work


  • Underreaction: prices impound forecast information sluggishly.
  • Anchoring: investors anchor on stale earnings rather than forward estimates.

  • Limitations and risks


  • Coverage requirement: followed firms only.
  • Forecast quality: depends on analyst-forecast accuracy.
  • Overlap: related to revisions and PEAD signals.
