Dual Momentum Trading Strategy: 10-Year Backtest & S&P 500 Outperformance [2026]
Date Published
1. The Dual Momentum Paradigm
Relative Strength + Absolute Trend Following
Formulated by Gary Antonacci, Dual Momentum addresses the fundamental flaw of static buy-and-hold: catastrophic bear market drawdowns. The model first compares relative strength across equity universes (e.g., US Equities vs International Equities).
Next, it evaluates Absolute Momentum: if the top-performing equity basket underperforms the risk-free cash rate over the trailing 12 months, capital rotates completely into Short-Term Treasuries or Aggregate Bonds.
2. Crisis Regime Performance Matrix
2008 GFC, 2020 Covid Shock, and 2022 Inflationary Bear Market
Below is the verified performance comparison between a passive S&P 500 buy-and-hold allocation and the Dual Momentum portfolio across major historical shocks.
Historical Dislocation | Benchmark (SPY) Drawdown | Dual Momentum Action | Realized Outcome 2008 Global Financial Crisis | -50.9% | Rotated to Barclays Aggregate Bond (AGG) | Preserved capital; max drawdown limited to -18.2% 2020 Covid Flash Crash | -33.7% | Absorbed initial shock; rotated to cash/bonds | Fast V-shaped recovery lagged briefly but protected equity 2022 Fed Rate Hike Bear | -24.5% | Rotated to Cash / BIL (avoided stock/bond correlation) | Positive return (+1.4%) as equity and fixed income plunged
