## 🔍 Features Implemented
### 1. Dividend Health Report (`dividend-health`)
Comprehensive analysis including:
- Current dividend yield and annual dividend
- Payout ratio (dividends / earnings)
- Free cash flow (FCF) coverage ratio
- Dividend growth rate (CAGR)
- Dividend Aristocrat status check (25+ years of increases)
- Cut probability score (0-100)
- Historical trends (5 years)
- Risk factor identification
### 2. Payout Ratio Analysis (`payout-ratio`)
Focused payout ratio analysis:
- Current payout ratio with trend direction
- 5-year historical trend
- Assessment: Critical / High Risk / Moderate / Healthy / Conservative
- Interpretation guidance
**Thresholds:**
- 30-60%: Ideal sustainable range
- >80%: High risk
- >100%: Paying more than earnings (critical)
### 3. FCF Coverage Analysis (`fcf-coverage`)
Free cash flow dividend coverage:
- Current FCF coverage ratio (FCF / Dividends Paid)
- Trend analysis (improving / stable / deteriorating)
- Assessment: Excellent / Good / Fair / Poor / Critical
**Thresholds:**
- >2.0x: Excellent coverage
- 1.5-2.0x: Good coverage
- 1.0-1.5x: Fair (minimal cushion)
- <1.0x: Poor (dividend at risk)
### 4. Dividend Cut Risk Score (`dividend-cut-risk`)
Probability of dividend cut (0-100 score):
- Multi-factor risk scoring model
- Risk factors identified with severity
- Mitigating factors (Dividend Aristocrat status, etc.)
- Actionable recommendation
**Risk Factors Analyzed:**
1. **Payout Ratio** (>80% = +25 pts, >100% = +40 pts)
2. **FCF Coverage** (<1.0x = +20 pts, <0.5x = +35 pts)
3. **Rising Payout Trend** (+15 pts)
4. **Negative Dividend Growth** (+10 pts)
5. **Short Dividend History** (+5 pts)
**Risk Levels:**
- 0-15: Very Low Risk (✅ Highly sustainable)
- 15-30: Low Risk (✅ Appears sustainable)
- 30-50: Moderate Risk (⚠️ Monitor closely)
- 50-70: High Risk (🚨 Cut probable)
- 70-100: Very High Risk (🚨 Cut highly likely)
### 5. Dividend Aristocrat Check
Automated detection of Dividend Aristocrat status:
- Checks for 25+ consecutive years of dividend increases
- Annual dividend aggregation from historical data
- Consecutive increase counting algorithm

## 📝 Notes
1. **Dividend Yield Display Issue:** Yahoo Finance data returns dividend_yield in inconsistent formats. The core analysis (payout ratio, FCF coverage, cut risk) is unaffected and working correctly.
2. **NaN Values in Historical Trends:** When financial data is unavailable for older periods (e.g., 5th year back), NaN appears. This is expected behavior and doesn't affect the analysis of available periods.
3. **Payout Ratio = 999:** Special marker indicating company is paying dividends despite zero or negative earnings. Treated as critical risk factor.
4. **Pandas Frequency Fix:** Updated `resample('Y')` → `resample('YE')` for pandas 2.0+ compatibility.
