## Piotroski F-Score

Calculate Piotroski's F-Score to evaluate a company's financial strength using 9 fundamental criteria.

### Instructions

```bash
uv run python scripts/piotroski.py SYMBOL
```

### What is Piotroski F-Score?

Piotroski's F-Score is a fundamental analysis tool developed by Joseph Piotroski that evaluates a company's financial strength using 9 criteria. Each criterion scores 1 point if passed, 0 if failed, for a maximum score of 9.

### The 9 Criteria

1. **Positive Net Income** - Company is profitable
2. **Positive ROA** - Assets are generating returns
3. **Positive Operating Cash Flow** - Company generates cash from operations
4. **Cash Flow > Net Income** - High-quality earnings (cash exceeds accounting profit)
5. **Lower Long-Term Debt** - Decreasing leverage (improving financial position)
6. **Higher Current Ratio** - Improving liquidity
7. **No New Shares Issued** - No dilution (or share buybacks)
8. **Higher Gross Margin** - Improving profitability efficiency
9. **Higher Asset Turnover** - More efficient use of assets

### Score Interpretation

- **8-9:** Excellent - Very strong financial health
- **6-7:** Good - Strong financial health
- **4-5:** Fair - Moderate financial health
- **0-3:** Poor - Weak financial health

### Output

Returns JSON with:
- `score` - F-Score (0-9)
- `max_score` - Maximum possible score (9)
- `criteria` - Detailed breakdown of each criterion with pass/fail status and values
- `interpretation` - Text description of financial health level
- `data_available` - Boolean indicating if year-over-year comparison data is available for criteria 5-9

### Implementation Details

- Criteria 1-4 use quarterly financial data (most recent year)
- Criteria 5-9 use annual financial data for year-over-year comparisons
- Compares most recent fiscal year vs previous fiscal year
