## CLI Commands
All three commands implemented and tested:
### 1. `earnings-tone TICKER`
```bash
python cli.py earnings-tone AAPL
```
Returns: Overall sentiment, hedging analysis, tone shift
**Test Result:** ✅ PASS
```json
{
"ticker": "AAPL",
"overall_sentiment": { "polarity": 0.81 },
"hedging_analysis": { "hedging_ratio": 6.07 },
"tone_shift": { "sentiment_change": -0.5 }
}
```
### 2. `confidence-score TICKER`
```bash
python cli.py confidence-score TSLA
```
Returns: Composite confidence score (0-100)
**Test Result:** ✅ PASS
```json
{
"ticker": "TSLA",
"confidence_analysis": {
"overall_confidence": 45.2,
"interpretation": "Moderate - Mixed signals"
}
}
```
### 3. `dodge-detect TICKER`
```bash
python cli.py dodge-detect NVDA
```
Returns: Q&A evasiveness analysis, dodge rate
**Test Result:** ✅ PASS
```json
{
"ticker": "NVDA",
"dodge_analysis": {
"total_questions": 3,
"dodge_rate": 0.0,
"interpretation": "Transparent - Direct and detailed answers"

## Technical Highlights
### Loughran-McDonald Dictionary
- Industry-standard financial sentiment lexicon
- Used in 1,000+ academic papers
- Excludes general-purpose sentiment (e.g., "tax" is neutral)
- High precision for financial text
### Confidence Scoring Formula
```python
confidence_score = (
(sentiment_polarity + 1) * 25 + # 0-50 from sentiment
(1 - hedging_ratio) * 30 + # 0-30 from low hedging
(confident_words + 0.05) * 200 # 0-20 from assertiveness
)
```
### Dodge Detection
- Compares answer length to question complexity
- Expected ratio: 2x words (detailed answers)
- High hedging in answers = dodge indicator
- Dodge score > 40 = likely evasive
### Tone Shift Analysis
- Prepared remarks = scripted, polished
- Q&A = spontaneous, revealing
- Defensive shift = sentiment drop + hedging increase
- Red flag for credibility issues
---
## API Integration (Next Steps)
The module is **CLI-ready** and **MCP-tool compatible**.
### MCP Tools Registered:
1. `analyze_earnings_tone(ticker)` → Full tone analysis
2. `get_confidence_score(ticker)` → Confidence scoring
3. `detect_question_dodging(ticker)` → Dodge detection
### Next.js API Routes (To Be Created):
```typescript
// /api/earnings/tone/[ticker]
// /api/earnings/confidence/[ticker]
// /api/earnings/dodge/[ticker]
```
**Note:** API route implementation is outside the scope of this Phase 47 build.

## Usage Examples
### Quick Start
```bash
# Get earnings tone for Apple
python cli.py earnings-tone AAPL
# Check management confidence for Tesla
python cli.py confidence-score TSLA
# Detect question dodging in Nvidia earnings
python cli.py dodge-detect NVDA
```
### Advanced Analysis
```python
from modules.earnings_nlp import (
analyze_sentiment,
analyze_confidence,
detect_question_dodging,
analyze_tone_shift
)
# Custom transcript analysis
sentiment = analyze_sentiment(transcript_text)
confidence = analyze_confidence(transcript_text)
tone_shift = analyze_tone_shift(prepared_remarks, qa_section)
```
