What is goals-based asset allocation and how does it use modules?

Question

AcadiFi · Accepted Answer

Goals-based asset allocation (GBAA) structures a private client's wealth into distinct sub-portfolios, each aligned with a specific goal, time horizon, and required probability of success. Unlike traditional mean-variance optimization that treats wealth as a single pool, GBAA acknowledges human cognition and biases by separating 'buckets' for safety, lifestyle, aspiration, and legacy.

Module concept: each goal is mapped to a pre-built portfolio module — a risk-appropriate mix optimized for that goal's characteristics. Common modules:

1. **Capital preservation (short-term)** — ~90% fixed income, 10% equity. Target: cover 1-3 years of expenses.
2. **Core lifestyle (medium-term)** — 40-60% equity, 40-60% fixed income. Target: cover 10-30 years of planned spending.
3. **Aspirational (long-term growth)** — 75-95% equity + alternatives. Target: fund discretionary goals (second home, business).
4. **Legacy/perpetual** — 70-85% equity + privates. Target: multi-generational wealth or charitable endowment.

Process:
1. List goals with horizon, amount, and priority (needs, wants, wishes).
2. Assign required probability of success (e.g., 95% for essential goals, 50% for wishes).
3. Map each goal to a module with appropriate expected return and volatility.
4. Size module allocations so total wealth covers each goal probabilistically.

Example: Althea Beringer (client) has $18M. Goals: $4M essential lifestyle 30 years, $6M children education 8-18 years, $5M aspirational second home 5 years, $3M legacy to grandchildren 50+ years. Modules: $4M in 60/40 lifestyle (95% success), $6M in 70/30 growth with glide path, $5M in 50/50 conservative-growth, $3M in 90/10 aspirational.

CFA candidates should understand GBAA trades some efficiency for client alignment — risk is measured per goal rather than across total wealth, which may leave some diversification on the table.
