HAA Balanced: How Keller's Canary Strategy Handles Bear Markets
The HAA balanced strategy, also known as Hybrid Asset Allocation — Balanced (HAA-B), offers a systematic approach to navigating volatile markets while pursuing steady growth. For investors seeking a middle ground between pure growth and maximum capital preservation, HAA-B stands out by blending tactical signals with asset class diversification. In an environment where traditional 60/40 portfolios have struggled during equity bear markets and bond drawdowns, the HAA balanced strategy addresses a critical challenge: how to participate in upside while containing losses during periods of severe market stress.
Understanding how HAA-B, and specifically Keller’s “Canary” adaptation, handles bear markets is essential for investors who want more than passive buy-and-hold or simplistic trend-following. By combining early warning signals with adaptive allocation, HAA-B aims to sidestep major drawdowns without sacrificing long-term returns. This article explores the mechanics of the strategy, its historical performance through multiple crises, and where it fits in the spectrum of tactical asset allocation. For those evaluating tactical approaches on PortfolioWiser, a data-driven understanding of HAA-B is vital for informed portfolio construction.
What Is the HAA Balanced Strategy?
The HAA balanced strategy is a rules-based asset allocation model that sits between aggressive tactical momentum and pure defensive frameworks. Inspired by Wouter Keller’s Hybrid Asset Allocation research, HAA-B combines multiple signals: trend-following, relative momentum, and—uniquely—the “Canary” early warning system. The goal is not just to chase returns, but to proactively reduce risk exposure when major market regime shifts are detected.
Unlike classic momentum or trend-following models that may swing fully between risk-on and risk-off assets, HAA-B seeks a smoother ride. It typically allocates across global equities, bonds, and alternative assets, with the allocation dynamically adjusted based on the health of “canary” assets—those that tend to deteriorate before broad market downturns. This approach is particularly relevant for investors wary of the maximum drawdown potential of buy-and-hold strategies.
How the HAA Balanced Strategy Works: Mechanisms and Signals
Step 1: Asset Universe Selection
HAA-B generally operates on a diversified universe, including U.S. and international equities, government bonds, inflation-protected securities, gold, and sometimes real estate or commodities. The blend is designed to provide exposure to multiple risk factors while avoiding overconcentration in any single asset class.
Step 2: The Canary Early Warning System
Central to Keller’s Canary approach is the use of specific “canary” assets—often small-cap equities and high-yield bonds. These assets tend to show weakness before broader markets roll over. When the canaries flash warning signals, the strategy shifts toward a more defensive allocation.
The mechanics of the canary signal typically involve a combination of trend and momentum filters. If enough canaries breach their risk thresholds, HAA-B reduces its allocation to risk assets and increases exposure to safer holdings such as Treasuries or cash.
Step 3: Adaptive Allocation Based on Signals
Each month, HAA-B evaluates both the canary warning and the trend/momentum status of the broader asset universe. If the canaries are “healthy,” the model allocates across the top-performing assets based on recent momentum and trend direction. If the canaries are “sick,” the model moves defensively—often concentrating in government bonds, TIPS, or gold.
This dual-layered decision-making process distinguishes HAA-B from strategies that rely on a single signal. It also means the model can remain partially invested in risk assets during mild corrections but will systematically de-risk during major regime changes.
Step 4: Rebalancing and Execution
HAA-B typically rebalances monthly, in line with common practice for tactical allocation. Investors can learn more about the practicalities of monthly rebalancing in Monthly Rebalancing: What to Do on Signal Day.
HAA Balanced Strategy Performance: Long-Term and Crisis Periods
Evaluating the HAA balanced strategy requires a look beyond headline return numbers. Its effectiveness lies in the interplay between growth and risk control, especially during bear markets. The following table summarizes HAA-B’s core metrics since inception:
| Metric | HAA Balanced (HAA-B) |
|---|---|
| Compound Annual Growth Rate (CAGR) | 10.21% |
| Maximum Drawdown (MaxDD) | -9.29% |
| Sharpe Ratio | 1.12 |
For context, these numbers place HAA-B well above traditional 60/40 portfolios on a risk-adjusted basis, and in line with other advanced tactical approaches. The Sharpe ratio of 1.12 indicates strong risk-adjusted returns, while the MaxDD of -9.29% reflects substantial drawdown mitigation relative to pure equity or even balanced static portfolios. For a deeper understanding of these risk metrics, see What Is Maximum Drawdown and Understanding Risk-Adjusted Returns.
Performance During Major Bear Markets
The real test for any tactical allocation model is its behavior during severe drawdowns. HAA-B’s canary mechanism is designed to rapidly de-risk when early warnings flash. The following table illustrates HAA-B’s crisis period performance during the most significant market shocks of the 21st century:
| Crisis Period | HAA-B Drawdown | S&P 500 Drawdown |
|---|---|---|
| 2008 Global Financial Crisis | +2.26% | -55.2% |
| 2020 COVID Crash | +2.99% | -33.9% |
| 2022 Rate Shock | +3.67% | -24.5% |
| 2025 (Scenario) | -2.02% | -22.8% |
The data shows HAA-B’s drawdowns remain in the single digits even when equity markets experience losses of 25% to over 50%. This pattern is consistent with the core goal of tactical allocation: capturing growth while minimizing the behavioral and mathematical consequences of large losses.

When the HAA Balanced Strategy Works—and When It Struggles
Strengths of HAA-B in Bear Markets
HAA-B’s greatest advantage emerges during fast, deep equity selloffs and protracted bear markets. The canary mechanism provides a lead time advantage over strategies that wait for broad asset weakness, enabling HAA-B to shift defensively before losses compound. Its diversified universe means that it can often find at least one asset class in an uptrend, further smoothing the equity curve and reducing volatility. This makes HAA-B particularly attractive for investors with a low tolerance for drawdowns or those relying on portfolio withdrawals.
Periods of Relative Underperformance
No strategy is invulnerable. HAA-B’s multi-signal, diversified approach means that in sharp, V-shaped recoveries—where markets rebound quickly after a crash—it can lag more aggressive trend-followers. Defensive allocations may persist for several months after the initial market bottom, leading to missed upside. This “whipsaw risk” is a common feature of tactical allocation; investors are sometimes late in re-engaging with risk assets after false positives from the canary signal.
Additionally, in environments where all asset classes decline together—such as 2022 when both stocks and bonds fell—HAA-B can only mitigate, not eliminate, drawdowns. Its risk control is robust but not absolute. For a detailed exploration of these limitations, refer to Anatomy of a Drawdown and Backtesting Pitfalls.
Comparing HAA Balanced with Traditional and Tactical Alternatives
HAA-B vs. 60/40 and Static Portfolios
Relative to a classic 60/40 or all-equity portfolio, HAA-B delivers higher risk-adjusted returns and dramatically lower drawdowns. The canary signal’s early warnings are a key difference, allowing for a more dynamic risk posture. In extended bull markets, a 60/40 can outperform on a nominal basis, but HAA-B’s protection during deep declines compounds over time thanks to the power of compounding and avoiding large losses.
HAA-B vs. Other Tactical Strategies
Compared with pure momentum or trend-following models, HAA-B exhibits less volatility and fewer “all-in/all-out” moves. It is more conservative than approaches like Bold Asset Allocation (BAA) or Dual Momentum, but more adaptive than static alternatives like the Permanent Portfolio or All Weather Portfolio. Investors can examine these distinctions in 7 Tactical Asset Allocation Strategies Compared and see how blending strategies can further stabilize outcomes in How to Blend Investment Strategies for a Smoother Ride.
While HAA-B is not the highest returning tactical model in runaway bull markets, its balance of defense and offense is supported by a long track record of “winning by not losing”. This makes it a strong candidate for core portfolio allocations, or as a complement to more aggressive tactical sleeves.

Conclusion: The Role of HAA Balanced Strategy in Modern Portfolios
The data shows that the HAA balanced strategy provides a compelling solution for investors seeking robust risk control without sacrificing long-term growth. By combining canary early warning signals, trend/momentum filters, and diversified asset selection, HAA-B has consistently minimized drawdowns in major bear markets while delivering a CAGR of 10.21% and a Sharpe ratio of 1.12. Its crisis period performance confirms its utility as a core holding or defensive anchor in a tactical portfolio.
No single approach is perfect, and HAA-B may lag during rapid recoveries or when all asset classes decline simultaneously. However, its measured response to risk and ability to adapt to changing regimes make it a resilient choice for those who value drawdown protection alongside growth. As with all systematic strategies, past performance does not guarantee future results, and ongoing diligence is required. For those looking to move beyond static allocation, the HAA balanced strategy merits careful consideration and hands-on exploration through PortfolioWiser’s research platform.
