Benchmark

A benchmark gives investors a meaningful point of comparison. Without one, it is impossible to know whether a portfolio's return of, say, eight percent in a given year reflects skill, luck, or simply a rising market that delivered ten percent to anyone who showed up. Families managing substantial wealth typically specify benchmarks formally inside an investment policy statement.

Benchmark selection matters more than it might seem. A portfolio of global equities judged against a domestic-only index is an apples-to-oranges comparison that can flatter or penalize a manager unfairly. Sophisticated families often use blended benchmarks — for example, a weighted mix of equity and fixed-income indexes — that reflect the actual asset allocation the portfolio is meant to maintain.

Consider a hypothetical family office holding a mix of public equities, private credit, and real assets. Choosing a pure stock index as the single benchmark would be misleading, since private and real assets behave very differently. Constructing a composite benchmark — even an imperfect one — produces a more honest conversation about results. The mechanics of benchmark use in practice are explored further at Benchmarks and Performance.

A common confusion: beating a benchmark does not automatically mean the portfolio did well in absolute terms, and trailing a benchmark does not automatically mean it did poorly. Context — particularly the level of risk taken — is essential to any honest evaluation.
