Portfolio Construction Memo

Date: January 14, 2026 Portfolio Universe: highwater, mt2x, persistent, tellurian, quantstrat, syntax, velox Risk-Free Rate: 4.00% Max Weight Constraint: 40.0% CVaR Alpha: 5.0%


1. Executive Summary

Recommended Allocation: MaxSharpe

MetricValue
Expected Return19.6%
Volatility1.9%
Sharpe Ratio8.35
CVaR (95%)-0.04%
Max Drawdown-0.41%

Rationale: The MaxSharpe portfolio delivers the highest risk-adjusted return among all optimization objectives, achieving a Sharpe ratio of 8.35 compared to 3.56 for EqualWeight. While the expected return is modestly lower than EqualWeight (19.6% vs 22.3%), the dramatic reduction in volatility (1.9% vs 5.2%) and tail risk (CVaR of -0.04% vs -0.26%) makes this the superior choice for institutional allocation. The portfolio maintains acceptable diversification while concentrating capital in the most efficient return-generating strategies.

Negative Correlations8 pairshighwater/persistent, highwater/syntax, mt2x/persistent, mt2x/syntax, tellurian/quantstrat, tellurian/syntax, quantstrat/velox, syntax/velox
Correlation > 0.50 pairsNone

Key Observations:

  • Exceptionally low inter-strategy correlations with maximum pairwise correlation of only 0.26 (persistent/syntax), indicating strong diversification potential
  • Eight strategy pairs exhibit negative correlations, providing natural portfolio hedging benefits
  • No high correlation concerns (all below 0.30), suggesting each strategy contributes unique return sources
  • The tellurian/quantstrat pair (-0.17) offers the strongest inverse relationship for tail risk mitigation

3.3 Analysis

  • MaxSharpe delivers 2.3x improvement in risk-adjusted returns over EqualWeight (Sharpe of 8.35 vs 3.56) by concentrating in velox (39.4%) and persistent (31.6%), which offer superior return-per-unit-risk characteristics
  • MinVar and CVaR portfolios favor quantstrat and velox, achieving the lowest volatility profiles (1.3-1.4%) but sacrificing 4-7 percentage points of expected return
  • RiskParity provides balanced exposure across strategies but delivers only 6.61 Sharpe, underperforming MaxSharpe by 26% on risk-adjusted basis
  • All optimized portfolios dramatically reduce tellurian and mt2x exposure (0.4-6.0% vs 14.3% EqualWeight), suggesting these strategies contribute noise without commensurate return

7.2 Conditions for Implementation

  1. Verify sufficient liquidity in velox and persistent to support 71% combined allocation without adverse market impact
  2. Confirm operational readiness for all seven strategies including trade execution infrastructure and risk monitoring systems
  3. Establish baseline performance attribution framework to distinguish strategy alpha from factor beta exposure

7.3 Key Risks to Monitor

RiskIndicatorMitigation
Concentration RiskTop 2 holdings exceed 70%Monitor correlation regime changes between velox/persistent; consider RiskParity as fallback allocation
Capacity ConstraintsSlippage exceeds 10 bps on rebalancePhase large trades over multiple sessions; explore alternative execution venues
Regime ChangeSharpe ratio falls below 4.0 for 3 consecutive monthsRe-run optimization with updated data; consider rotation to MinVar or CVaR portfolio
Correlation BreakdownAny pairwise correlation exceeds 0.5Immediate review of affected strategies; reduce combined exposure if persistent
