A beat doesn't guarantee a rally, and a miss doesn't guarantee a drop, expectations already priced in can flip the reaction.
Beat/miss alone doesn't say how big, a company that beats by 0.1% every quarter behaves very differently from one that swings ±20%.
| Avg Surprise | Median | Largest Beat | Largest Miss | |
|---|---|---|---|---|
| EPS | +693.9% | +122.2% | +3520.0% | -64.0% |
| Revenue | +6.3% | +7.7% | +11.5% | -2.9% |
More analysts covering a stock generally means more scrutiny and (often) tighter estimates.
