Composite Dual Momentum and Multi-Lookback Strategies

The original dual momentum framework — pick the best asset by relative strength, then check absolute momentum — is powerful but limited by its single-pair, single-lookback design. The strategies in this article extend that framework in three distinct directions: Composite Dual Momentum (CDM) applies paired rotation across four independent asset modules; Dual Momentum Top 6 (DUAL_T6) replaces traditional momentum with SMA-ratio scoring across a broad universe; and ADM Inflation Protected (ADM_IP) adds inflation-protected bonds to the defensive sleeve.

Composite Dual Momentum (CDM)

Parameter	Value
Universe	SPY, EFA, LQD, HYG, VNQ, REM, GLD, TLT (8 assets in 4 pairs)
Risk-Off Asset	BIL
Lookback	12 months
Momentum Method	REL_STR_1P (12-month return)
Allocation	PAIRED (25% per module)

Four Independent Modules

CDM, developed by Gary Antonacci, structures its 8-asset universe into four distinct modules, each representing a different asset class. This is not a single ranking of all 8 assets — it is four independent head-to-head competitions, each allocated 25% of the portfolio:

Module	Pair	Weight
Equity	SPY vs EFA	25%
Credit	LQD vs HYG	25%
Real Estate	VNQ vs REM	25%
Commodity/Bond	GLD vs TLT	25%

Within each module, the engine compares the 12-month returns of the two assets and selects the relative winner. The winner then undergoes a trend health check — if the winner fails the trend health assessment, that module's 25% allocation moves to BIL instead. This per-module defensive mechanism means the portfolio can be partially defensive (e.g., 50% in risk assets and 50% in BIL) when some asset classes are struggling while others are thriving.

Why Paired Rotation Matters

The paired structure enforces permanent asset class diversification. Unlike a single-ranking strategy that might put 100% into equities when they are leading, CDM always maintains exposure across four distinct categories. Even in the strongest equity bull market, the equity module receives only 25% — the remaining 75% is allocated based on independent competitions in credit, real estate, and commodity/bond markets.

Each pair is also carefully constructed to offer meaningful internal rotation. SPY vs EFA captures US-versus-international equity momentum. LQD vs HYG captures the investment-grade versus high-yield credit decision. VNQ vs REM distinguishes between equity REITs and mortgage REITs. GLD vs TLT represents the choice between real assets and duration — two fundamentally different hedges against economic uncertainty.

Dual Momentum Top 6 (DUAL_T6)

Parameter	Value
Universe	SPY, QQQ, IWM, VGK, EWJ, EEM, IYR, GSG, GLD, HYG, LQD, TLT (12 assets)
Risk-Off Asset	IEF
Top-N	6
Lookback	12 months
Momentum Method	SMA_RATIO (price / SMA(12) - 1)
Protection	ABSOLUTE (exclude negative momentum)
Allocation	Equal weight

SMA Ratio Scoring

DUAL_T6 uses a distinctive momentum method derived from Keller and Keuning's PAA (Protective Asset Allocation) research. Instead of ranking by raw return, it scores each asset using the SMA ratio: current price divided by the 12-month simple moving average, minus 1. An asset trading 10% above its SMA has a score of 0.10. An asset trading 5% below its SMA has a score of -0.05.

This scoring method has a useful property: it measures trend position rather than magnitude of return. Two assets might both have positive 12-month returns, but the one trading further above its moving average is exhibiting stronger current trend behavior. The SMA ratio captures this distinction that raw returns miss.

The Filtering Process

Each month, the engine ranks all 12 assets by SMA ratio. Assets with negative scores — those trading below their 12-month SMA — are excluded entirely, regardless of their relative ranking. From the remaining positive-momentum assets, the top 6 receive equal weight. If fewer than 6 assets have positive momentum, the shortfall is allocated to IEF. In an extreme scenario where no assets have positive momentum, the entire portfolio moves to IEF.

Holding 6 of 12 assets creates a highly diversified portfolio that is less sensitive to any single asset's behavior. Combined with the absolute momentum filter, this produces a strategy that maintains broad exposure during healthy markets and progressively de-risks as momentum deteriorates across the universe.

ADM Inflation Protected (ADM_IP)

Parameter	Value
Risk-On Assets	SPY, SCZ
Risk-Off Assets	TLT, TIP
Top-N	1
Lookback	6 months
Momentum Method	ADM = average(R1M, R3M, R6M)
Protection	ABSOLUTE

The Inflation-Protection Enhancement

ADM_IP shares the same risk-on universe and scoring method as standard ADM — it ranks SPY against SCZ (international small-cap) using the average of 1-month, 3-month, and 6-month returns. The key difference is the defensive sleeve. Standard ADM uses only TLT (long-term Treasuries) as its risk-off asset. ADM_IP adds TIP (Treasury Inflation-Protected Securities) as a second defensive option, selecting whichever has the higher 1-month return when the portfolio goes defensive.

This addition addresses a specific vulnerability in the standard ADM design. During inflationary rate-hiking environments (like 2022), TLT can suffer massive drawdowns, making it a poor defensive asset precisely when protection is needed most. TIP, while also rate-sensitive, has an inflation adjustment that partially offsets rate-driven losses during inflationary periods. By selecting between TLT and TIP each month, ADM_IP adapts its defensive posture to the current inflation and rate environment.

Which Variant Fits

CDM suits investors who want disciplined asset class diversification with per-module safety valves. DUAL_T6 suits those who want broad, diversified exposure with a unique momentum signal and progressive de-risking. ADM_IP suits investors who like the ADM framework but want better protection during inflationary environments.

For the foundational dual momentum concepts underlying all three strategies, see dual momentum explained. For strategies that use optimization rather than equal weighting to allocate among selected assets, see classical and adaptive asset allocation.

Each of these variants addresses a real limitation of the original dual momentum design — whether that is concentration risk (CDM), binary defensive behavior (DUAL_T6), or inflation vulnerability (ADM_IP). Understanding these extensions helps investors select the variant whose specific enhancements match their particular concerns.
