Risk & Allocation

What a risk questionnaire can and cannot measure

A short set of questions produces a single score that bundles together three separate things, only one of which is about your feelings.

There is a settled way of talking about risk profiling questionnaires. It is worth asking how much of it survives contact with the detail.

The argument in brief

  • Capacity for loss, tolerance for loss and need for risk are distinct questions.
  • Most questionnaires collapse them into one score.
  • Answers vary with mood and with how questions are framed.

Three questions in one score

Capacity asks what a substantial fall would do to your life, tolerance asks how you would behave, and need asks how much risk your goal actually requires. These can point in completely different directions for the same person.

A single score obscures the disagreement, which is precisely the information you needed. Answering them separately, in writing, is more informative than any composite output.

Framing moves the answers

The same choice described in terms of gains and in terms of losses reliably produces different responses. Questions using percentages get different answers from questions using currency amounts, and currency is the more realistic framing. Whether the questionnaire mentions a time horizon at all changes what people are answering about.

None of this means the instruments are useless, but it does mean the score has wide error bars.

They are asked in the wrong state

Profiling happens in calm conditions, and the behaviour it predicts occurs under stress. People generally underestimate how differently they will act when the loss is real and current.

For most people, a questionnaire completed during a market fall would produce a different profile, which tells you how stable the measurement is. The output is best treated as a conversation starter rather than a measurement.

What they do well

They are consistent, documented and force consideration of questions people would otherwise skip entirely. In many countries they play a regulatory role in demonstrating that suitability was considered, which is a genuine protection. They also surface obvious mismatches, such as someone needing money in two years while selecting a high-risk profile.

Catching the obvious cases is worth having even if precision is limited.

Improving your own answers

Convert every percentage in the questionnaire into your own currency before answering. Answer the capacity questions from your actual obligations rather than from how confident you feel. If you have notes from a previous market fall, use them; they are better evidence than introspection.

Where your answers to different questions conflict, that conflict is the finding worth discussing.

Where the real decision sits

The output of a questionnaire is an input to an allocation decision, not the decision itself. The decision also depends on horizon, other resources, guaranteed income and rules that differ substantially by country.

The useful part is this: nothing general can determine what is suitable for an individual, which is what regulated advice exists to do. Treating a score as an answer is the main way these tools get misused.

The takeaway

Answer capacity, tolerance and need separately. The single score hides the one that binds.

Pick the one that costs you least, and let the rest wait.

Questions readers ask

Should I ignore risk questionnaires?

No. Use them to force the questions, then answer capacity, tolerance and need separately in your own words. The composite score is the least useful part.

Why do different questionnaires give me different results?

Because wording, framing and weighting differ, and because your answers vary with mood. The variation is a fair indication of the precision available.
