Every investment committee seems to end with the same recommendation: diversify more. At Westwick, while we do not disagree with diversification as a principle, we disagree with it as a substitute for conviction.
For example, a family investing across generations does not need exposure to Japanese equities by way of a Nikkei ETF for the sake of diversifying. What they might need is a stake in a Tokyo-based medtech raising capital to secure an international patent: a business they have met, that they believe in, and whose trajectory they can influence. One is averaging. The other is investing.
Families are long-term by construction and strategic by nature. That means conviction, not diffusion. It means internal ratings coherent with the family office's purpose, and the discipline to say no to everything that falls outside them. It also means accepting to be wrong sometimes in exchange for being right over the cycle.
This is what separates family capital from institutional capital. An institution paid on tracking error can accept a bad quarter if the index is down more. A family cannot. Its reference point is not the market. It is its own long-term preservation and growth target. That target is harder than beating a benchmark, and it is met by choosing carefully, not by diversifying widely.
Putting that discipline on paper — the objectives stated, someone accountable for each decision, and the reason for it on record — is what an asset allocation oversight review sets up.
Frequently asked questions
Should a family office diversify its portfolio or maintain investment discipline?
Diversification has become the default answer in family office investment committees, but families are not institutions seeking to reduce tracking error. They seek long-term capital preservation and growth. The choice is not between diversification and concentration. It is between a coherent investment philosophy and the absence of one.
What is the right investment approach for a single family office?
A family office should build its investment approach around the family's actual purpose and time horizon, not around industry benchmarks. The families that preserve wealth across generations choose assets they understand and hold them with discipline, rather than chasing diversification for its own sake.
