Factor Overlap Risk? Your Diversification Is Fake
Stock-bond correlation: +0.28 — crossed the +0.25 threshold. Weight drift compounds the vol breach. According to MAD Risk Parity Portfolios, the MAD-based risk budgeting framework informs how multi-factor overlap shapes a Risk Parity allocation across sleeves.

Evidence of Volatility Budget Breach Under RP Allocation
Current weights: Equity 38%, Bond 32%, Commodity 30%. Realized vol: 13.0%. Breach: 0.5 percentage points. Trigger met. Stock-bond correlation: +0.34 — post regime shift (delta +0.06 from prior +0.28). Weight drift compounds the vol breach. Rebalance action: New target weights: Equity 33%, Bond 46%, Commodity 21%.

Correlation Shift Mechanism and Risk Budget Redistribution
Current weights: Equity 33%, Bond 46%, Commodity 21%. Realized vol: 12.8%. Breach: 0.0 percentage points. Trigger: not breached. Stock-bond correlation: +0.34 — correlation regime shift informs risk budgeting. The allocation math shows the +0.06 delta increases cross-sleeve risk contributions under MAD constraints. Rebalance action: New target weights: Equity 31%, Bond 52%, Commodity 17%.
| Asset | Current Weight % | Sharpe | Volatility % | Max Drawdown % |
|---|---|---|---|---|
| Equity | 33 | 0.70 | 14.0 | 19 |
| Bond | 46 | 0.28 | 6.7 | 7 |
| Commodity | 21 | 0.42 | 12.1 | 15 |
Final Construction Verdict and Exact Rebalancing Instructions
Current weights: Equity 31%, Bond 52%, Commodity 17%. Realized vol: 13.0%. Breach: 0.5 percentage points. Trigger met. The correlation shift requires a disciplined reallocation to preserve risk parity across sleeves. Rebalance now. You implement the following target weights: Equity 29%, Bond 56%, Commodity 15%.

FAQ
Does risk parity overlap with value or momentum in a Risk Parity Portfolio?
Yes, factor overlap with value or momentum affects how risk is allocated across sleeves in a Risk Parity Portfolio. The MAD Risk Parity Portfolios framework shows that multi-factor overlap influences cross-sleeve risk contributions, with a correlation reading around +0.34 during regime shifts. This overlap requires explicit MAD-based risk budgeting to preserve parity across sleeves. MAD Risk Parity Portfolios.
Back to Factor Overlap Risk? Your Diversification Is FakeWhat threshold breach triggers a rebalancing under MAD-based RP?
A vol budget breach of 0.5 percentage points triggers a rebalancing. The correlation reading is +0.34, signaling a regime shift in cross-sleeve risk. Rebalance action follows the MAD-based target weights to preserve risk parity across sleeves. MAD Risk Parity Portfolios.
Back to Factor Overlap Risk? Your Diversification Is FakeWhat are the current target weights after the latest threshold-driven adjustment?
New target weights are Equity 29%, Bond 56%, Commodity 15%. The latest read shows realized vol at 13.0% and Equity Sharpe 0.72 with Bond Sharpe 0.25. This adjustment demonstrates the RP portfolio rebalanced to preserve risk parity across sleeves. MAD Risk Parity Portfolios.
Back to Factor Overlap Risk? Your Diversification Is FakeExecution Roadmap for Threshold-Driven Risk Parity Rebalancing
You are implementing a threshold-driven rebalancing to Equity 29%, Bond 56%, Commodity 15% when the vol breach reaches 0.5 percentage points and the cross-sleeve correlation reads +0.34. This realignment preserves risk parity across sleeves and aligns with MAD-based risk budgeting dynamics.
Next, you execute the rebalancing steps: compute marginal risk contributions, minimize turnover within a tax-efficient window, ensure allocation percentages sum to 100%, and monitor for correlation regime shifts to trigger future adjustments. This plan maintains a systematic, threshold-driven approach to risk parity portfolio construction.
