How to Set a Strategic Asset Allocation

Start with obligations and the time available

A long-horizon allocation is a plan for distributing a portfolio among broad asset categories, not a prediction of which one will lead next year. Begin with the purpose of the assets, expected withdrawals, known liquidity needs, and the time each portion can remain invested. A near-term obligation may call for a different reserve from money intended for a distant goal.

Risk capacity and willingness are related but not identical. A household may be comfortable with price changes yet lack the financial capacity to wait through a deep loss, or have the capacity but prefer a steadier path. The plan should account for both without turning a questionnaire result into a guaranteed allocation.

Choose target ranges before selecting products

Write target weights or ranges for the major exposures first, then identify holdings that can implement them. Broad categories may include equities, bonds, cash, and other assets when they fit the purpose. The right classification depends on actual holdings and risks; a fund name alone can conceal concentration or credit exposure.

A range makes room for market movement while keeping the policy distinct from a short-term forecast. Document why the chosen mix fits the stated horizon and liquidity needs. There is no allocation percentage that is appropriate for every person, institution, or goal.

Define how drift will trigger review

A rebalancing rule can use a calendar review, a tolerance band, or a combination. Calendar checks are predictable but may trade when little has changed; bands respond to drift but require monitoring and a decision about transaction costs. The plan should specify what is measured and how a trigger is applied.

Use contributions, withdrawals, or available cash when they can move the portfolio toward its target without unnecessary sales. That approach may reduce trading, but it does not guarantee a higher return or eliminate taxes and fees. Record when a practical constraint justifies an exception.

• Write down the target and the date it was approved.
• State which holdings count toward each exposure.
• Set a review rule and the conditions for changing it.

Review the policy when its assumptions change

A change in cash needs, time horizon, legal obligations, or the portfolio's purpose may warrant a policy review. A market decline alone does not automatically invalidate a long-term allocation, but it can reveal that the assumed loss tolerance was unrealistic. Separate changes in circumstances from discomfort with recent performance.
