Bold Asset Allocation (BAA): Balancing Offense and Defense
Bold Asset Allocation (BAA) represents the evolution of Wouter Keller's tactical framework. Published in 2022, it builds on the lessons learned from DAA, VAA, and HAA to create a strategy that balances offensive returns with defensive protection more effectively than its predecessors.
BAA's key innovation is its graduated defense mechanism: instead of a binary switch between fully offensive and fully defensive, BAA adjusts the defensive allocation proportionally based on how many canary assets show weakness. This graduated response reduces the whipsaw problem that plagues more aggressive defensive systems while maintaining strong crash protection.
How BAA Works
Three Universes
BAA operates with three distinct groups of assets:
Canary Universe (risk detection):
- A broader set of economically sensitive assets than DAA's two-asset canary
- Typically includes emerging market equities, high-yield bonds, U.S. aggregate bonds, and other risk-sensitive assets
- These assets are monitored for negative momentum as early warning signals
Offensive Universe (growth assets):
- U.S. equities (SPY)
- International developed equities (EFA)
- Emerging market equities (EEM)
- Real estate (VNQ)
- Commodities (DBC)
- Additional equity exposures depending on the variant
Defensive Universe (safe haven assets):
- Short-term Treasuries (BIL, SHV)
- Intermediate Treasuries (IEF)
- Long-term Treasuries (TLT)
- Aggregate bonds (AGG)
The Graduated Defense Mechanism
BAA's defensive allocation scales with the number of negative canary signals:
- 0 canaries negative: 100% offensive — invest in the top-ranked offensive assets
- 1 canary negative: Partially defensive — shift a portion to defensive assets
- 2 canaries negative: More defensive — increase the defensive allocation
- All canaries negative: Fully defensive — move entirely to the top-ranked defensive asset
The exact proportions vary by variant (balanced vs. aggressive), but the principle is consistent: defense increases proportionally with the breadth of market weakness. One weak canary might trigger 25% defensive allocation. Two might trigger 50%. All negative might trigger 100%.
Why Graduated Defense Works Better
Consider a scenario where emerging market equities briefly dip negative while all other canary assets remain positive. Under VAA's "any single negative" rule, this triggers full defensive positioning — potentially missing a month of gains across the rest of the portfolio.
Under BAA's graduated approach, the same scenario triggers only a partial defensive shift (perhaps 25% to safety). If the emerging market weakness is a false alarm, the cost is minimal — 75% of the portfolio remained invested. If the weakness spreads to other canary assets in subsequent months, the defensive allocation increases progressively, building protection as danger escalates.
This proportional response is more aligned with how market stress actually develops. Crises rarely arrive as a single, sudden event. They typically begin in one corner of the market (credit, emerging markets, small caps) and spread over weeks or months. BAA's graduated defense mirrors this progression.
BAA Variants
BAA-Balanced (BAA-B)
The balanced variant uses moderate parameters that favor steady returns with good protection:
- Moderate canary universe sensitivity
- Equal weighting between offensive assets when invested
- Typical time in full defense: 15-25% of months
BAA-Aggressive (BAA-A)
The aggressive variant concentrates on the top-ranked offensive assets for maximum return:
- Invests in fewer top-ranked assets (top 1-3 instead of equal weight)
- More willing to stay offensive during partial canary weakness
- Higher return potential but with more concentrated positions
Historical Performance
- CAGR: Approximately 9-13% (depending on variant)
- Maximum drawdown: Approximately −10% to −16%
- Sharpe ratio: Approximately 0.7-1.1
- Time in partial/full defense: Approximately 25-40% of months
BAA's performance sits between VAA (more defensive) and pure momentum strategies (more offensive). It captures more upside than VAA during bull markets while providing meaningful drawdown protection during crises.
Compared to DAA
BAA and DAA share the canary signal concept, but BAA's broader canary universe and graduated response produce different behavior:
- BAA catches some early warnings that DAA's two-asset canary misses
- BAA's graduated response reduces the "all or nothing" whipsaw of DAA's binary switch
- BAA's offensive asset ranking is typically broader, capturing more diversification
The 2022 Stress Test
BAA handled the 2022 environment better than many static and even some tactical strategies:
- Canary assets began showing weakness in early 2022 as bonds deteriorated
- BAA progressively increased defensive allocation through Q1-Q2 2022
- Defensive asset selection favored short-term Treasuries (the only bond category with positive performance)
- By mid-2022, the portfolio was heavily defensive, avoiding the worst of both the equity and bond decline
The graduated response meant BAA stayed partially invested during the early phase of the decline (capturing some remaining positive performance from commodities and energy) while building defensive positioning as the stress broadened.
Combining BAA with Other Strategies
BAA works exceptionally well as a core holding in a multi-strategy portfolio. Its graduated defense provides a stable anchor while other strategies contribute different return profiles:
- BAA + Pure Momentum: BAA provides the defensive floor while momentum strategies capture aggressive upside during strong trends
- BAA + Sector Rotation: BAA manages the broad asset allocation while sector rotation captures within-equity opportunities
- BAA + Macro Timing: BAA's price-based signals complement macro strategies' economic data-based signals, creating a multi-signal defense system
On PortfolioWiser, BAA variants are available with full backtest data, allocation heatmaps, and comparison tools. You can blend BAA with other strategies to build custom portfolios that match your specific risk-return objectives.
Practical Considerations
Monthly Execution
BAA requires checking signals once per month at month-end. The process:
- Calculate 13612W momentum for all canary assets
- Count the number with negative momentum
- Determine the defensive allocation percentage
- Rank offensive assets by momentum for the offensive portion
- Rank defensive assets by momentum for the defensive portion
- Execute trades
This is slightly more complex than a binary strategy like GEM, but the calculations are straightforward and PortfolioWiser automates them entirely.
Rebalancing Precision
BAA's graduated positions (e.g., 75% offensive / 25% defensive) require more precise position sizing than all-or-nothing strategies. For smaller portfolios, rounding to the nearest share can create meaningful deviations from target weights. Most practitioners accept deviations of up to 2-3% as immaterial.
Tax Considerations
BAA's moderate turnover makes it more tax-friendly than VAA but less tax-efficient than buy-and-hold. Holding BAA in a tax-advantaged account eliminates the tax drag entirely and is the recommended approach for most investors.
Frequently Asked Questions
Is BAA better than DAA?
BAA and DAA have different strengths. BAA's broader canary universe and graduated defense typically produce smoother returns with fewer whipsaws. DAA's simpler two-asset canary is easier to understand and implement. In backtests, BAA generally shows slightly better risk-adjusted returns, but the difference is modest enough that either is a strong choice.
Should I use BAA-Balanced or BAA-Aggressive?
BAA-Balanced is better for core portfolio allocations and risk-averse investors. BAA-Aggressive is better as a satellite component within a diversified multi-strategy portfolio. If BAA is your only strategy, BAA-Balanced is the safer choice.
How does BAA handle sudden crashes?
Like all monthly-rebalancing strategies, BAA cannot fully avoid sudden intra-month crashes (like March 2020). However, if canary assets were already showing weakness before the crash, BAA would have partial defensive positioning in place. The graduated mechanism means some defense is usually active before a major event, even if it is not maximum defense.
