Robust Asset Allocation — Aggressive (RAA-GRAY-A)
Developed by Wes Gray · Dual Momentum · Med-High Risk
The Aggressive variant of Robust Asset Allocation applies Wes Gray's dual confirmation philosophy to a concentrated two-asset equity universe with a binary allocation model. Where the balanced variant maintains a diversified three-asset portfolio with per-position protective overlays, the aggressive variant makes a single all-or-nothing decision: hold the stronger equity market if conditions are favorable, or shift entirely to bonds if they are not. This concentrated approach amplifies both the potential returns during confirmed equity trends and the protective benefits of the dual confirmation filter.
Like its balanced counterpart, RAA-GRAY-A requires both a moving average trend filter and an absolute return check to agree before committing capital to equities. The strategy compares US equities (SPY) against international equities (EFA) using trailing twelve-month relative strength to select the stronger market, then subjects the winner to the dual confirmation test. If the winning equity market passes both the trend and absolute return checks, the entire portfolio is allocated to that single position. If the winner fails either check, the portfolio shifts entirely to intermediate bonds (IEF).
The binary allocation model produces a strategy whose behavior is distinctly different from the balanced variant. Rather than maintaining persistent multi-asset exposure with selective defensive overlays, the aggressive variant is always fully committed to one of two positions: the strongest equity market or bonds. This concentration means the portfolio experiences the full volatility of whichever position it holds, with no diversification buffer between equity and fixed income during any given month.
Gray's dual confirmation filter is critical in this concentrated context. Without the dual confirmation requirement, a single-indicator binary strategy would generate frequent whipsaws — each producing a full portfolio rotation between equities and bonds. The dual gate substantially reduces these false signals, ensuring that full equity commitment only occurs when both trend and absolute return confirm favorable conditions. The result is a high-conviction strategy with surprisingly moderate turnover — typically making only a few transitions per year despite its binary nature.
How It Works
Relative Strength Selection
Each month, US equities (SPY) and international equities (EFA) are compared by their trailing twelve-month total returns. The asset with the higher return is designated the relative strength winner and becomes the candidate for the portfolio's sole equity allocation. This relative comparison captures the multi-year US-versus-international rotation cycles driven by relative monetary policy, currency movements, and earnings growth differentials.
Dual Confirmation Gate
The relative winner must pass both confirmation tests before receiving allocation. The trend test checks whether the winner's price is above its ten-month simple moving average, confirming a positive trend trajectory. The absolute return test checks whether the winner's trailing twelve-month return is positive, confirming that the asset has generated positive absolute gains over the lookback period.
If the winner passes both tests, the entire portfolio is allocated to that single equity position. If either test fails, the portfolio shifts entirely to intermediate bonds (IEF). The dual requirement means the strategy tolerates temporary price weakness (below the moving average but with positive trailing returns) and temporary return weakness (negative recent returns but still above the moving average) without triggering a defensive switch. Only confirmed weakness — negative on both dimensions — produces a transition.
Concentrated Risk Profile
The all-or-nothing allocation creates a portfolio with binary risk characteristics: during equity periods, the portfolio carries the full volatility and drawdown risk of a single equity market with zero diversification; during bond periods, the portfolio carries intermediate-duration interest rate risk with zero equity exposure. There is no intermediate positioning.
This concentration amplifies the importance of signal accuracy. When the dual confirmation correctly identifies a favorable equity environment, the full equity allocation maximizes return capture. When it correctly identifies an unfavorable environment, the full bond allocation maximizes capital preservation. The strategy's value proposition depends entirely on whether the dual confirmation filter is right more often than a random coin flip — and whether the magnitude of its correct calls exceeds the magnitude of its errors. Historical evidence suggests the dual gate achieves this, but the concentrated format means individual months of incorrect positioning can produce significant tracking error relative to balanced approaches.
