Asset correlation management
The Hidden Driver of Portfolio Risk
Effective correlation management reduces volatility without sacrificing returns through strategic diversification.
Core Correlation Concepts
1. Correlation Spectrum
| Correlation Range | Relationship | Portfolio Impact |
|---|---|---|
| +1.0 to +0.7 | Strongly Positive | Limited diversification benefit |
| +0.3 to +0.7 | Moderately Positive | Some risk reduction |
| -0.3 to +0.3 | Uncorrelated | Ideal diversification |
| -0.3 to -0.7 | Moderately Negative | Strong risk reduction |
| -0.7 to -1.0 | Strongly Negative | Potential hedging |
2. Dynamic Correlation Patterns
- Correlations increase during market crises
- Sector correlations change with economic cycles
- Safe-haven assets often become negatively correlated in downturns
