How Can a Family Avoid Changing Course Because of Short-Term Market Moves?

Build the investment plan around the family's needs and time horizons, then use it to assess market moves. In my experience, families get into trouble when they treat a short-term price change as a reason to rewrite a long-term strategy without checking what the family needs from its capital.

Start With the Family's Time Horizons

Separate capital for near-term spending from money intended for intermediate goals and long-term preservation or growth. Each pool can have its own tolerance for volatility and illiquidity. If funds are needed soon, a temporary decline can matter more than it does for capital that can remain invested through a full cycle.

This framework also makes performance easier to interpret. Consider a manager's result in light of the role assigned to that manager, the time horizon, and the purpose of the allocation. Comparing every investment with the same short-term measure can encourage decisions that do not fit the family's needs. The return targets for each portfolio segment should reflect those distinct purposes.

Write Down What Would Change the Plan

Before a period of market stress, document why the family chose its allocations, which risks it accepted, and what conditions would lead to a review. That record can distinguish new information about an investment from discomfort caused by price movement alone. A review may be warranted when the investment thesis changes, the family's liabilities change, or the portfolio no longer fits its agreed limits.

Set a regular review cadence and use it consistently. Scheduled discussions give the committee a place to examine results and liquidity, along with changes in the family's circumstances, without turning every market move into an emergency. The way to assess whether the strategy is working should be clear before the review begins.

Give Decisions a Clear Owner

Define who can make routine adjustments, who approves a material allocation change, and what information the family needs before a decision. A clear process helps keep the discussion focused on the original objective and the evidence available. Record the reason for a change, including its effect on liquidity and the family's longer-term plan.

When a proposed shift is driven by near-term volatility, compare it with the investment policy and the family's spending needs. Ask whether the change solves a genuine mismatch or responds to a difficult period. The risk of permanent loss deserves attention alongside short-term results. Liquidity planning can reduce pressure to sell at an unfavorable time.

A family does not need to ignore market information. It needs a disciplined way to decide whether that information changes the plan. When the investment purpose and decision authority are written down, and review conditions are set, short-term moves become inputs to a process instead of prompts to abandon it.

The more important question for the family office is what type of strategies managers should build within each one of these asset buckets that match the liability bucket.
