Capabilities

• Value at Risk (VaR) calculation
• Volatility analysis
• Drawdown measurement
• Concentration risk assessment
• Correlation analysis
• Stress testing
• Risk-adjusted return metrics
• Risk management recommendations

When to Activate

Activate this skill when the user requests:

• “Analyze my portfolio risk”
• “What’s my VaR?”
• “Calculate portfolio volatility”
• “Check concentration risk”
• “Stress test my portfolio”
• “Risk metrics for my holdings”
• “Is my portfolio too risky?”

Process

1. Gather Portfolio Data: Collect holdings, weights, and historical data
2. Calculate Risk Metrics: Compute VaR, volatility, beta, correlations
3. Assess Concentration: Analyze position and sector concentration
4. Measure Drawdown: Calculate current and historical drawdowns
5. Stress Test: Apply historical and hypothetical scenarios
6. Generate Recommendations: Provide actionable risk management advice

Risk Analysis Framework

1. Portfolio Overview

## Portfolio Risk Overview

**Portfolio Value**: ${Total Value}
**Number of Holdings**: {Count}
**Analysis Date**: {Date}
**Analysis Period**: {Start} to {End}

### Quick Risk Summary
| Metric | Value | Status |
|--------|-------|--------|
| Annual Volatility | XX.X% | {Low/Moderate/High} |
| Beta | X.XX | {Defensive/Neutral/Aggressive} |
| Sharpe Ratio | X.XX | {Poor/Fair/Good/Excellent} |
| Max Drawdown (1Y) | -XX.X% | {Acceptable/Concerning/Severe} |
| Daily VaR (95%) | -${X,XXX} | {Within tolerance / Elevated} |

2. Value at Risk (VaR)

## Value at Risk Analysis

### VaR Calculations
| Confidence | 1-Day VaR | 1-Week VaR | 1-Month VaR |
|------------|-----------|------------|-------------|
| 95% | -${X,XXX} (-X.X%) | -${X,XXX} (-X.X%) | -${XX,XXX} (-X.X%) |
| 99% | -${X,XXX} (-X.X%) | -${X,XXX} (-X.X%) | -${XX,XXX} (-X.X%) |

### VaR Interpretation
- **95% Daily VaR of -${X,XXX}** means:
  - 95% confidence that daily loss won't exceed ${X,XXX}
  - ~1 in 20 days may see losses greater than ${X,XXX}
  - Not a maximum loss - tail events can exceed VaR

### Conditional VaR (Expected Shortfall)
| Confidence | CVaR | Interpretation |
|------------|------|----------------|
| 95% | -${X,XXX} | Average loss when loss > VaR(95%) |
| 99% | -${X,XXX} | Average loss when loss > VaR(99%) |

CVaR captures tail risk better than VaR.

3. Volatility Analysis

## Volatility Analysis

### Historical Volatility
| Timeframe | Volatility | Benchmark | Relative |
|-----------|------------|-----------|----------|
| 10-day | XX.X% | XX.X% | {Higher/Lower} |
| 30-day | XX.X% | XX.X% | {Higher/Lower} |
| 90-day | XX.X% | XX.X% | {Higher/Lower} |
| 252-day | XX.X% | XX.X% | {Higher/Lower} |

### Volatility Components
- **Portfolio Volatility**: XX.X% (annualized)
- **Systematic Risk**: XX.X% (market-driven)
- **Idiosyncratic Risk**: XX.X% (stock-specific)
- **Diversification Benefit**: X.X% (volatility reduction from diversification)

### Beta Analysis
- **Portfolio Beta**: X.XX
- **Interpretation**: Portfolio moves X.XX% for every 1% market move
- **Risk Profile**: {Conservative β<0.8 / Moderate 0.8-1.2 / Aggressive β>1.2}

• Compare to benchmarks when possible
• Prioritize actionable recommendations
• Acknowledge model limitations

Constraints

• Risk models are approximations
• Historical data may not predict future
• Correlations change during market stress
• VaR doesn’t capture tail risk fully
• This is analysis, not investment advice
• Consider personal risk tolerance
