What is the difference between strategic and tactical asset allocation?

Question

AcadiFi · Accepted Answer

Strategic asset allocation (SAA) establishes a long-term policy mix aligned with the investor's objectives, constraints, and capital-market expectations. Tactical asset allocation (TAA) deliberately deviates from SAA to exploit short-term mispricing or changing risk premia, then reverts toward the policy weights.

Key differences:
- **Horizon**: SAA spans 5-20 years, reviewed every 3-5 years. TAA operates over 1-12 months.
- **Input drivers**: SAA uses long-run equilibrium returns, risk, and correlations. TAA uses business-cycle indicators, valuation spreads, momentum, and sentiment.
- **Risk budget**: TAA is allocated a tracking-error budget (e.g., 150-300 bps) relative to SAA.
- **Governance**: SAA decided by investment committee; TAA by CIO or asset-allocation team within policy ranges.

Example: Tremaledge Endowment's SAA is 50% global equity, 25% bonds, 15% private assets, 10% real assets, with ±7% ranges. A 2026 TAA view shows US equity overvalued versus emerging markets by 15% P/E differential, prompting a tilt of -3% US, +3% EM within the equity sleeve. The TAA budget caps tracking error at 200 bps.

Value-add debate: academic studies show TAA struggles to beat SAA net of costs, but skilled managers can add 50-100 bps annually. SAA still drives 85-90% of return variability per Ibbotson-Kaplan. CFA candidates must distinguish both from dynamic asset allocation (regime-based, longer horizon than TAA) and rebalancing (risk control, not alpha seeking).
