Benchmarks for model portfolios: how small RIAs choose, record and change them
A benchmark is the index, or blend of indices, a model portfolio is measured against. For a small RIA, the operational work is choosing one benchmark per model that reflects what the model actually holds, recording it in the model's definition and in the IPS of accounts that follow it, and keeping a dated history when it changes, so any past comparison can be reproduced with the benchmark that applied at the time.
A client asks how their portfolio did against "the market". The adviser answers with one index. The quarterly report uses another. The IPS names a third, chosen years ago for a model that has since changed. None of them is wrong on its own. Together they make the answer impossible to check.
What is a benchmark for?
It gives a reference point: a reasonable comparison for what the model is trying to do. A balanced model measured against an all-stock index will look poor in rising markets and great in falling ones, which tells the client very little.
How do you choose one per model?
| Question | Why it matters |
|---|---|
| Does it match what the model holds? | Asset classes, regions and style should line up with the model's allocation |
| Single index or blend? | A blend often fits a multi-asset model better than one index |
| Is the data available and consistent? | You need to be able to reproduce the comparison later |
| Can you explain it in one sentence? | If a client can't follow it, it won't help the conversation |
Where should the benchmark be recorded?
- In the model's definition, alongside its allocation and rebalancing rules.
- In each version of the model, so a model revision that changes the benchmark is dated.
- In the IPS of accounts that follow the model, if the IPS describes how performance is measured.
- In reports, named clearly, with the period it applies to.
A worked example
Take a hypothetical firm with three models: growth, balanced and income. It assigns a blended benchmark to each that mirrors the model's stock and bond split.
| Model | Benchmark | Recorded |
|---|---|---|
| Growth | Blend weighted mostly to a broad stock index | Model v3, effective 1 January |
| Balanced | Even blend of a stock index and a bond index | Model v2, effective 1 January |
| Income | Blend weighted mostly to a bond index | Model v4, effective 1 July (changed when the model added income stocks) |
When the income model changed in July, the benchmark changed with it. Comparisons before July use the old benchmark, after July the new one, and both are on record.
Common mistakes
- One benchmark for every model, regardless of what it holds.
- Changing the benchmark without dating it, so past comparisons can't be reproduced.
- The IPS and the report naming different benchmarks.
- Choosing a benchmark after the fact because it makes results look better.
When is this overkill?
A firm with one model needs one benchmark, written down once. The versioning matters as soon as models change or multiply.
How Advorra fits
In Advorra, each versioned model carries its benchmark alongside its allocation, rebalancing rules and philosophy, chosen from a catalog of 147 indices, and the IPS fills the benchmark from the client's strategy. See the product page, or read model versions and the strategy of record and time-weighted vs money-weighted returns.
One thing to do this week: for each model, check that the benchmark in the model, the IPS and your last client report is the same one.
About recording benchmarks consistently, not investment advice. Ask your compliance consultant before using benchmark comparisons in marketing.
Questions advisors ask
Can one benchmark be a blend of indices?
Yes. A blended benchmark, for example a mix of a stock index and a bond index, often matches a balanced model better than a single index. Record the blend and how often it is rebalanced.
How often should a benchmark change?
Rarely, and only for a reason such as a change in the model's strategy. Frequent changes make comparisons hard to trust.
Should the benchmark be in the IPS?
If the IPS describes how the portfolio is measured, yes, and it should match the model. When the benchmark changes, update the IPS too.
Does using a benchmark affect marketing?
Showing performance against a benchmark in marketing has its own rules. Ask your compliance consultant before using benchmark comparisons in any advertising.
Is this investment advice?
No. It is about recording and maintaining benchmarks consistently. Choosing them is the adviser's decision.
