# Piotroski F-Score

## What is F-Score?

A 9-point scoring system that evaluates a company's financial strength based on profitability, leverage, and efficiency metrics.

## Think of it like this

Like a report card with 9 pass/fail tests - the more you pass, the healthier the company.

## Formula

```
F-Score = Sum of 9 binary (0 or 1) criteria
```

- **Profitability (4)**: ROA, CFO, ΔROA, Accruals
- **Leverage (3)**: ΔLeverage, ΔLiquidity, Equity Issue
- **Efficiency (2)**: ΔMargin, ΔTurnover

## Why it matters

- Academic research shows high scores outperform
- Identifies financially strong value stocks
- Simple binary scoring is easy to understand
- Developed by Stanford professor Joseph Piotroski

## What's a good value?

| Range | Rating | What it means |
|---|---|---|
| 0-3 | Weak | Poor financial health, avoid |
| 4-5 | Average | Mixed signals, proceed with caution |
| 6-7 | Good | Solid financial position |
| 8-9 | Excellent | Strong fundamentals, quality company |

## Real-world example

A score of 8 means the company passed 8 of 9 financial health tests.
