What is Earnings Surprise?
Definition
An earnings surprise occurs when a company's reported earnings per share differs from the consensus estimate of Wall Street analysts. A positive surprise (beat) typically lifts the stock price, while a negative surprise (miss) usually causes a decline.
Detailed Explanation
Earnings surprise is calculated as the difference between actual EPS and the consensus analyst estimate. Academic research has documented the 'post-earnings announcement drift' (PEAD) effect, where stocks that beat estimates tend to continue rising for weeks or months afterward.
However, not all surprises are created equal. The quality of the beat matters. A company that beats EPS through lower taxes will see a smaller reaction than one that beats through higher revenue and margins. A revenue miss combined with an EPS beat is often viewed negatively.
The 'whisper number' is an unofficial expectation that may differ from the published consensus. This is why stocks sometimes fall even after technically 'beating' consensus estimates.
About 70-75% of S&P 500 companies beat estimates in a typical quarter, partly because companies manage expectations through conservative guidance.
Formula
Earnings Surprise = Actual EPS - Consensus Estimated EPS
Surprise % = ((Actual EPS - Estimated EPS) / |Estimated EPS|) x 100Example
If analysts estimated EPS of $2.00 and the company reported $2.20, the earnings surprise is +$0.20, or +10%.
