Multi-Dimensional Risk Framework
While most platforms focus on simple volatility measures, Parallax monitors risk across multiple dimensions:Factor Risk
- Concentration Monitoring: Prevent overexposure to any single factor
- Interaction Effects: Track how factors correlate during stress
- Style Drift: Ensure portfolios maintain intended exposures
Market Risk
- Volatility Tracking: Real-time portfolio volatility measurement
- Beta Management: Control systematic market risk exposure
- Correlation Analysis: Monitor changing relationship patterns
Concentration Risk
- Position Limits: Maximum exposure to individual securities
- Sector Concentration: Industry and geographic exposure controls
- Factor Concentration: Prevent over-reliance on single factors
Liquidity Risk
- Trading Volume: Ensure adequate liquidity for position changes
- Market Impact: Estimate costs of portfolio adjustments
- Stress Liquidity: Model liquidity during market stress periods
