6. Risk-Budgeting in GUQFXP: Portfolio-Level Noise & Allocation

Introduction

Effective risk management in GUQFXP hinges on allocating a fixed total noise budget across all 28 FX pairs, ensuring no single currency dominates your stop‐risk footprint. Under Law 7: Portfolio-Level Noise Budget, we define a global risk budget B and distribute it proportionally according to each pair’s relative volatility (DAATS). This deep dive shows you how to compute Noise-Sharei, allocate risk, explore alternative weighting schemes, and perform vital aggregation checks.

1. Defining the Total Noise Budget (Law 7)

Law 7 mandates that the portfolio’s total stop-risk (the sum of all individual Death-Stop distances) equals a predefined budget B. In GUQFXP, we set:

  • Total Noise Budget (B): 0.50% of equity

This means the combined risk of all 28 positions (if all stops were hit) never exceeds 0.50% of your account. By distributing this budget via Noise-Share, you align position sizing to each currency’s volatility contribution.

2. Computing Noise-Sharei from DAATSi

For each pair i:


// 1. Gather DAATS for all pairs
DAATS_i = fetchDAATS(i, timeframe="M1440")

// 2. Compute Noise-Share
NoiseShare_i = DAATS_i / Σₖ DAATS_k

Example (sample pairs):


Pair     | DAATS  | Noise-Share (≈)
---------|--------|----------------
EUR/USD  | 13,048 | 0.2744
GBP/USD  | 12,000 | 0.2524
AUD/USD  | 11,500 | 0.2419
NZD/USD  | 11,000 | 0.2313

These shares sum to 1.0 across your 28-pair universe.

3. Allocating 0.50% Risk Per Pair

Once Noise-Sharei is known, assign each pair a risk allocation:


// Total risk budget B = 0.005 (0.50%)
RiskAlloc_i = NoiseShare_i × B

Example (continued):


Pair     | Noise-Share | Risk-Alloc (% Equity)
---------|-------------|----------------------
EUR/USD  | 0.2744      | 0.2744 × 0.50% ≈ 0.1372%
GBP/USD  | 0.2524      | 0.1262%
AUD/USD  | 0.2419      | 0.1210%
NZD/USD  | 0.2313      | 0.1157%

This ensures ΣiRiskAlloci = 0.50% total risk. GATS then sizes each position so that its individual stop‐loss equals its RiskAlloci.

4. Alternative Weighting Schemes

While Noise-Share is default, you can tilt allocations using other schemes:

  • Carry-Weighted: wi ∝ carryYieldi Weights based on interest-rate differentials; good for carry trades but may overexpose low-volatility pairs.
  • Risk-Parity (Inverse Volatility): wi ∝ 1/σi Balances volatility contributions; smooths P&L but may underweight high-carry, high-vol pairs.
  • Equal Risk Contribution (ERC): solve for weights w such that: wi·σi·Σj(wj·σj·ρij) = constant Ensures each pair contributes equally to portfolio risk considering correlations; most robust but requires correlation matrix.

Select the scheme that matches your strategic emphasis—carry yield vs. volatility balance vs. equalized risk.

5. Practical Risk-Aggregation & Concentration Checks

To validate your allocations:

  1. Sum-of-Risk Check: Verify ΣiRiskAlloci = B (0.50%).
  2. Max Concentration Rule: Cap any single RiskAlloci ≤ C_max (e.g. 20% of B) to avoid overconcentration.
  3. Correlation Adjustment: If two pairs have ρ > 0.85 (e.g. EUR/USD & GBP/USD), ensure combined risk ≤ C_pair_max (e.g. 25% of B).
  4. Stress Testing: Simulate simultaneous stop hits on top 5 DAATS pairs—ensure total loss ≤ B under worst-case scenarios.

Conclusion

Under Law 7, Noise-Share risk budgeting gives GUQFXP a principled, volatility-anchored allocation that keeps total stop-risk within 0.50% of equity. Alternative weighting schemes and rigorous aggregation checks let you adapt the portfolio to different market objectives—be it carry focus, volatility balance, or equal risk contribution.
