# Earnings Surprise

## What is EPS Surprise?

The percentage difference between reported earnings and analyst expectations.

## Think of it like this

Like a student getting a 95% on a test when everyone expected an 80% - the surprise matters as much as the grade.

## Formula

```
Surprise % = (Actual EPS - Estimated EPS) ÷ |Estimated EPS| × 100
```

- **Actual EPS**: Reported earnings per share
- **Estimated EPS**: Average analyst estimate
- **Surprise**: Positive = beat, Negative = miss

## Why it matters

- Stocks often move sharply on surprises
- Consistent beats suggest management skill
- Misses can trigger significant selling
- Sets expectations for future guidance

## What's a good value?

| Range | Rating | What it means |
|---|---|---|
| > 10% | Big Beat | Strongly exceeded expectations |
| 2-10% | Beat | Modest outperformance |
| -2% to 2% | In Line | Met expectations |
| < -2% | Miss | Disappointed investors |

## Real-world example

A 15% earnings surprise often leads to stock jumps of 5-15% on earnings day.
