Cross-Asset Drawdown Control

Research ID QP-260714-A17F · Generated 14 Jul 2026

78Confidence
Decision summary

The candidate portfolio historically reduced maximum drawdown from −31.4% to −18.7%, while lowering annualized return by 0.6 percentage points. The drawdown objective was met in the illustrative sample, but inflation-shock dependence and BTC-weight sensitivity remain material risks.

Objective

Maintain long-term growth while keeping historical maximum drawdown at or below 20%. Existing assets may be reweighted and SGOV may be added.

Current portfolio issue

BTC represents 22% of capital but approximately 61% of estimated variance. SPY and SCHD also share substantial equity-factor exposure.

Candidate allocation

30% SPY · 28% GLD · 10% BTC · 12% SCHD · 20% SGOV. Quarterly rebalance with 5 bps assumed cost.

Key evidence

Walk-forward evaluation, transaction-cost range of 5–20 bps, parameter perturbation, leakage checks and five stress scenarios.

Risks & failure conditions

  • Fast inflation shock causes cross-asset diversification to weaken.
  • Result is sensitive to BTC weights above 15%.
  • Future correlations and liquidity may differ from the sample.

Next step

Review tax and execution constraints, validate with the user's actual account data, then paper-track the candidate before any rebalance decision.

Illustrative demo results only. Not actual performance, a recommendation, or a forecast. The user remains responsible for any investment decision.
