4. Correlation Analysis
The strategy correlation matrix reveals favorable diversification characteristics:
| highwater | mt2x | persistent | tellurian | quantstrat | syntax | velox | |
|---|---|---|---|---|---|---|---|
| highwater | 1.00 | 0.29 | -0.10 | 0.05 | 0.03 | -0.05 | 0.06 |
| mt2x | 0.29 | 1.00 | -0.04 | 0.27 | 0.04 | -0.03 | 0.02 |
| persistent | -0.10 | -0.04 | 1.00 | 0.04 | 0.13 | 0.30 | 0.07 |
| tellurian | 0.05 | 0.27 | 0.04 | 1.00 | -0.22 | -0.04 | 0.07 |
| quantstrat | 0.03 | 0.04 | 0.13 | -0.22 | 1.00 | 0.12 | -0.05 |
| syntax | -0.05 | -0.03 | 0.30 | -0.04 | 0.12 | 1.00 | -0.02 |
| velox | 0.06 | 0.02 | 0.07 | 0.07 | -0.05 | -0.02 | 1.00 |
Key Observations:
- Average pairwise correlation is near zero, indicating excellent diversification potential
- Velox exhibits low correlation with all other strategies (range: -0.05 to +0.07)
- Quantstrat shows negative correlation with tellurian (-0.22), providing hedge characteristics
- Persistent and syntax show moderate positive correlation (0.30), warranting combined weight monitoring
5. Risk Analysis
5.1 Drawdown Profile
The MaxSharpe_CDaR portfolio demonstrates exceptional drawdown control:
- Maximum Drawdown: -0.21% (vs. -1.34% for equal weight)
- CDaR (5%): -0.08% (conditional drawdown at risk)
- Drawdown Reduction: 84% improvement vs. equal weight benchmark
5.2 Volatility Decomposition
The 1.77% portfolio volatility is achieved through:
- Concentration in low-volatility strategies (velox, persistent, quantstrat)
- Diversification benefits from near-zero correlations
- Minimal exposure to higher-volatility strategies (tellurian, highwater)
5.3 Tail Risk Considerations
The CDaR optimization explicitly targets left-tail risk, resulting in:
- Smoother return distribution
- Reduced sensitivity to extreme market events
- Improved compounding efficiency over the investment horizon
6. Implementation Considerations
6.1 Rebalancing Frequency
Given the low-volatility nature of the portfolio, we recommend:
- Monthly rebalancing with +/- 5% drift tolerance
- Quarterly full reoptimization to capture regime changes
6.2 Capacity Constraints
Current allocations assume no capacity constraints. Monitor:
- Velox capacity at 38% allocation
- Combined quantstrat/persistent allocation at 50%
6.3 Transaction Costs
The concentrated allocation (4 strategies > 5%) minimizes rebalancing costs:
- Fewer positions to adjust
- Larger position sizes improve execution efficiency
7. Recommendation
Primary Recommendation: MaxSharpe_CDaR Portfolio
We recommend implementing the MaxSharpe_CDaR allocation for the following reasons:
- Superior Risk-Adjusted Returns: Sharpe ratio of 8.82 represents the highest among all optimization objectives
- Drawdown Control: Maximum drawdown of -0.21% provides capital preservation during adverse conditions
- Diversification Efficiency: Near-zero correlations between major holdings maximize diversification benefits
- Implementation Simplicity: Four-strategy concentration (velox, persistent, quantstrat, syntax comprising 97%) simplifies operations
Alternative Consideration:
For investors with higher risk tolerance seeking maximum absolute returns, the EqualWeight portfolio offers:
- 26.94% expected return (vs. 19.65%)
- At the cost of 5.34% volatility and -1.34% max drawdown
- Sharpe ratio of 4.29 (vs. 8.82)
