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 | -43.1% | +16.6% | +32.3% | -438.9% |
| Revenue | -7.8% | -11.1% | +30.7% | -39.6% |
More analysts covering a stock generally means more scrutiny and (often) tighter estimates.

| Q3 | -211.2% | -4.5% | 2 |
| Q4 | +1.4% | -4.1% | 2 |
