Portfolios & risk

Two people, one portfolio, two risk profiles

The instinct is to average them. That produces a portfolio that suits neither and leaves the actual disagreement undiscussed.

It is extremely common

Two people with shared finances routinely produce meaningfully different answers on the same questionnaire, and the difference is usually stable rather than random.

Why averaging fails

It produces an allocation that is too aggressive for one and too conservative for the other. In a decline, the more cautious partner is holding something they never wanted, and the conversation that produces is worse than the one you avoided.

Separate the dimensions first

Frequently what looks like a difference in tolerance is a difference in information, or in whose income the household depends on, or in who has been through a serious decline before.

Capacity is a household calculation and is the same number for both of them. That reframing alone resolves a good proportion of these.

The disagreement is usually not about risk. It is about who feels responsible if it goes wrong.

The practical approaches

Weight toward the more cautious partner, on the basis that the constraint binds. Segment by purpose, so shorter-horizon money is held more conservatively and both can see why. Or, where accounts genuinely are separate, allow them to differ.

The conversation to have

Ask each of them separately what specifically they are worried about. The answers are usually different in kind rather than in degree, and neither has said it out loud.

Do not let one speak for both

In many couples one partner leads financial conversations. The other is still a client, will still be affected, and is frequently the one who calls during a decline.

An adviser who has never had a direct conversation with the quieter partner has a relationship with one client and a risk with the other.
