How should strategic geographic equity allocation be determined?

Question

AcadiFi · Accepted Answer

Four common strategic geographic allocation frameworks: **1. Market-cap weights (MSCI ACWI)** — US ~60%, Int'l Developed ~28%, EM ~12%. Pros: efficient, reflects available capital, low tracking error to global benchmark. Cons: heavy US concentration, backward-looking (reflects past performance). **2. GDP weights** — weights tied to country share of global GDP. US ~24%, China ~18%, Europe ~15%, Japan ~4%, rest spread. Pros: forward-looking economic relevance, more EM exposure. Cons: GDP doesn't equal investable market cap; China underweight to its economy. **3. Regional block targets** — e.g., 50% US, 25% Europe, 10% Japan/Pac, 15% EM. Pros: simple, strategic judgment overlays, tactical flexibility. Cons: subjective, may drift from efficient allocation. **4. Risk-parity or equal-risk contribution** — weights set so each region contributes equally to portfolio risk. Result: smaller US weight (~40%), larger EM weight (~20%). Pros: diversification maximization. Cons: higher turnover, sensitive to volatility estimates. **Framework for choosing**: - Liability currency? → Tilts toward matching currency regions. - Return forecasting view? → Overweight regions with more attractive expected returns (tactical). - Risk tolerance? → Risk parity reduces tail risk but introduces estimation risk. - Benchmark constraints? → Consultants often require MSCI ACWI-relative allocation. Worked example: Hollisbrook Foundation (US-based, spending-rate-driven) sets strategic equity: 50% US, 25% Int'l Dev, 10% EM, 15% global small-cap. This blends market cap benchmark with a modest EM overweight and dedicated small-cap sleeve. 10-year expected returns: US 6.8%, Int'l Dev 7.2%, EM 8.5%, small-cap 7.5%. Blended: 7.1% vs 6.9% pure ACWI. ```mermaid graph TD A[Strategic Allocation] --> B[Market Cap
