Rebalancing

Rebalancing is the process of adjusting a portfolio when its actual asset allocation moves away from policy targets or ranges. Drift can result from market performance, capital calls, distributions, spending, new contributions, or valuation changes. The office buys, sells, or directs cash flows so the portfolio returns toward the agreed structure.

Rebalancing is disciplined, but not automatic in every circumstance. Taxes, transaction costs, liquidity, lock-ups, market capacity, and ownership restrictions can make immediate trading undesirable or impossible. Policy ranges allow the investment committee to distinguish meaningful drift from normal movement.

Why it matters for family offices

Without rebalancing, assets that recently performed well can become an increasingly large source of risk. A repeatable process encourages selling some appreciated exposure and adding to underweight areas, which can have the effect of buying lower and selling higher over time. It does not guarantee gains, and an underweight asset can continue falling after purchase.

Family offices need a consolidated view because each account can appear balanced while the whole family is not. Private assets complicate the calculation through delayed values and limited ability to sell. The office may rebalance public portfolios around them, change the pace of new commitments, or use incoming cash rather than force an illiquid transaction.

How it shows up in practice

Suppose a family's policy range for public equities is 30 to 40 percent. Strong markets push total exposure to 44 percent after direct shares and fund look-through are included. At the same time, private fund distributions create $3 million of cash. The office compares selling, directing the cash to bonds, and waiting for an expected tax payment.

The committee uses part of the cash to add fixed income and trims shares in the most concentrated account, bringing equities to 39 percent without selling private assets. It records the tax and liquidity considerations behind the choice. Rebalancing has restored policy risk through coordinated cash flows rather than a mechanical trade in every entity.
