Date: January 16, 2025 Recommendation: APPROVE Proposed Allocation: Core portfolio allocation (100% of strategy capital)
1. Executive Summary
| Metric | Value | Source |
|---|---|---|
| CAGR | 23.12% | _summary.csv (CVX optimal) |
| Annualized Volatility | 2.47% | _summary.csv |
| Sharpe Ratio | 7.75 | _summary.csv |
| Max Drawdown (Velox) | -0.48% | full_period/allocator_summary.csv |
| Max Drawdown (QuantStrat) | -1.20% | full_period/allocator_summary.csv |
| Max Drawdown (Persistent) | -1.46% | full_period/allocator_summary.csv |
Investment Thesis: This three-strategy portfolio enhances the Velox/QuantStrat combination by adding Persistent, a higher-return strategy with moderate volatility. The addition of Persistent increases CAGR from 14.91% to 23.12% (+55% improvement) while maintaining an exceptional Sharpe ratio above 7.7. The low cross-correlations among all three strategies (all <0.11) provide robust diversification. The CVX optimizer allocates 65% to Persistent and 35% to Velox, effectively zeroing out QuantStrat due to its inferior risk-adjusted return profile relative to the other strategies.
Key Strengths:
- Highest absolute return portfolio (23.12% CAGR)
- Sharpe ratios consistently above 7.5 across optimization methods
- Three-way low correlation provides multi-layered diversification
- 2024 delivered exceptional 32.45% return with 9.06 Sharpe

3.3 Performance Commentary
Persistent emerges as the return engine with 22.73% CAGR and a 6.31 IR, complementing Velox's superior risk-adjusted performance (9.34 IR). The 2024 period was exceptional, with the portfolio delivering 32.45% return while maintaining a Sharpe above 9. QuantStrat, while still positive, is dominated on both absolute and risk-adjusted basis by the other strategies, leading the optimizer to effectively zero it out.
4. Factor Exposure
Status: Factor analysis not performed for this portfolio run.
Recommended Follow-Up:
- Run factor regression against BTC, ETH, and funding rate factors
- Assess systematic beta exposures, particularly for Persistent given higher volatility
- Evaluate correlation regime sensitivity (Persistent to market beta)
- Test for common factor loadings that may reduce realized diversification under stress
5. Risk Analysis
5.1 Correlation Matrix
| Velox | QuantStrat | Persistent | |
|---|---|---|---|
| Velox | 1.000 | -0.040 | 0.061 |
| QuantStrat | -0.040 | 1.000 | 0.106 |
| Persistent | 0.061 | 0.106 | 1.000 |
Source: full_period/correlation.csv
Correlation Assessment: All pairwise correlations are extremely low (<0.11), indicating genuine diversification across all three strategies. The highest correlation is between QuantStrat and Persistent (0.106), which is still negligible. This correlation structure supports the portfolio's ability to compound returns with lower volatility than individual strategies suggest.
5.2 Drawdown Analysis
| Strategy | Max Drawdown | Context |
|---|---|---|
| Velox | -0.48% | Excellent drawdown control |
| QuantStrat | -1.20% | Acceptable |
| Persistent | -1.46% | Moderate, consistent with higher vol profile |
| Period | Velox DD | QuantStrat DD | Persistent DD |
|---|---|---|---|
| 2023 | -0.22% | -0.83% | -0.92% |
| 2024 | -0.23% | -1.20% | -1.46% |
| 2025 YTD | -0.48% | -0.40% | -0.32% |
Drawdown Commentary: All strategies maintain tight drawdown control. Persistent's higher max drawdown (-1.46%) is proportionate to its higher volatility and return. The lack of coincident large drawdowns across strategies validates the diversification thesis.
5.3 Key Risks
| Risk | Severity | Mitigation |
|---|---|---|
| Persistent Concentration | Medium-High | CVX allocates 65% to Persistent; monitor capacity and regime sensitivity |
| QuantStrat Zero Allocation | Low | Optimizer decision based on risk-return; can reintroduce if Sharpe improves |
| Persistent Higher Vol | Medium | Accept 2.99% vol for 22.73% return; monitor for vol spikes |
| Correlation Regime Shift | Medium | Low current correlations may increase during market stress |
| Limited History | Medium | 2-year track record; continue monitoring through market cycles |

6.2 CVX Optimizer Details
| Metric | Value |
|---|---|
| Solver | SCS |
| Status | Optimal |
| Position Caps Applied | 65% max (binding on Persistent) |
| Turnover (1-norm) | 1.0 |
| Solve Time | 0.05ms |
Optimizer Behavior: The CVX optimizer maximizes Sharpe ratio subject to position limits. It allocates to the cap (65%) on Persistent due to its superior return profile, while maintaining 35% in Velox for its exceptional risk-adjusted performance. QuantStrat is effectively zeroed (-1.2e-9, effectively 0%) because its risk-return profile is dominated by the other two strategies.
6.3 Bootstrap Stability Analysis
| Asset | Mean Weight | Std Dev | 95% CI |
|---|---|---|---|
| Velox | 35.90% | 5.12% | [35.0%, 65.0%] |
| QuantStrat | 0.00% | 0.00% | [0.0%, 0.0%] |
| Persistent | 64.10% | 5.12% | [35.0%, 65.0%] |
Stability Assessment: Bootstrap analysis reveals some variability between Velox and Persistent allocations (both can range from 35% to 65% depending on the sample), reflecting similar return profiles. However, QuantStrat consistently receives zero allocation across all bootstrap samples, confirming its dominated status. The optimizer is choosing between Velox and Persistent, with Persistent winning on average due to higher absolute returns.
7. Comparison to Portfolio 1 (Velox + QuantStrat Only)
| Metric | Portfolio 1 | Portfolio 2 | Delta |
|---|---|---|---|
| CAGR | 14.91% | 23.12% | +8.21pp (+55%) |
| Volatility | 1.36% | 2.47% | +1.11pp (+82%) |
| Sharpe Ratio | 8.01 | 7.75 | -0.26 (-3%) |
| Max Strategy DD | -1.20% | -1.46% | +0.26pp |
Comparison Commentary: Adding Persistent increases expected return by 55% at the cost of 82% higher volatility and a modest 3% Sharpe reduction. This trade-off is favorable for investors seeking higher absolute returns who can tolerate the additional volatility. Portfolio 2 remains an exceptional risk-adjusted portfolio with Sharpe >7.7.
8. CIO Recommendation
Decision: APPROVE
Recommended Allocation: CVX Optimal (35% Velox / 0% QuantStrat / 65% Persistent)
Rationale:
- Highest Absolute Returns: 23.12% CAGR exceeds Portfolio 1 by 55%
- Strong Risk-Adjusted Returns: Sharpe ratio of 7.75 remains exceptional
- True Diversification: All pairwise correlations below 0.11
- Consistent Performance: Positive Sharpe >8 in all periods
- Bootstrap Validation: Zero allocation to QuantStrat is consistently optimal
