Earnings Expectation Management and Announcement Return Patterns
Summary
The article reviews research linking firms’ incentives to manage investor expectations with earnings announcement premiums and seasonal stock returns. It builds an ex ante expectation management incentive score from analyst coverage and institutional ownership (attention), revenue growth (pressure), and an Altman solvency measure (earnings sensitivity), combined using principal component analysis. The proposed mechanism is that firms lower expectations before announcements, then benefit from positive earnings surprises and upward price adjustment.
In historical US equity data, firms with higher scores showed a V-shaped return pattern: weaker returns before earnings announcements and stronger returns in announcement months. The reported premium and seasonal strategy returns were concentrated among high-score firms, and the article describes robustness checks against other return predictors and alternative incentive measures. These are historical findings from a particular sample and measurement approach, not a guarantee of future performance. The score uses indirect company characteristics, and the article’s summary of foreign-market evidence does not establish that the same strategy will work in other markets or periods.
Key ideas
- The proposed incentive score combines attention, growth pressure, and sensitivity of share prices to earnings news.
- The study associates high scores with weaker pre-announcement returns and stronger announcement-month returns.
- The article links this pattern to firms lowering expectations before earnings reports to make positive surprises more likely.
- Reported seasonal return effects are strongest among firms with higher incentive scores.
- The evidence is historical and depends on indirect proxies for firms’ motives.
