The Four Levers Are Filters, Not Scores

What the levers actually do

Most investing questionnaires give you a number. Higher is treated as better, or at least as permission to take more risk. The Four Levers work the other way. They are filters. They tell you which methods will feel like work you can sustain and which will feel like swimming upstream until you quit.

The four are time horizon (including patience), wealth stage, risk temperament, and life bandwidth. None of them is complicated on its own. The combination is what matters. Get the combination wrong and you will fight your own strategy. Get it right and a large part of the noise disappears, because you stop trying to be someone you are not.

Why a score is the wrong metaphor

Imagine two investors. One has a long calendar horizon, high bandwidth, and genuine comfort with drawdowns, but needs the money in three years for a house deposit. The enthusiasm and the spare evenings do not cancel the cash deadline. The filter fails on time horizon and wealth stage. Growth stocks and concentrated trading are out, regardless of how interesting they look.

Another has decades until retirement and a stable job, but sold in March 2020 and has not trusted themselves since. Risk capacity is high. Risk temperament, revealed by behaviour, is not. Building a portfolio for the capacity and ignoring the temperament produces the same outcome next time: a sale at the wrong moment.

A filter either passes or it does not. Averaging the levers into a single score hides the failure.

How they interact

• Time horizon is three clocks: when you need the capital, how often you review, and how long you can watch something underperform before you crack. The third one is the one most people skip.
• Wealth stage is accumulation, preservation, or drawdown. The methods that built the money are often the wrong methods once you are living off it.
• Risk temperament is what you did last time, not what you said on the form. Capacity is maths. Temperament is behaviour.
• Life bandwidth is hours per week you can actually give, not hours you wish you had. High-bandwidth methods punish neglect.

Change one and the force on the others changes. A redundancy moves wealth stage, time horizon and bandwidth in a single afternoon. Retirement moves the binding constraint from growth to sequence of returns. A new child moves bandwidth whether you admit it or not.

What a filter produces

It produces a shortlist, not a prescription. Some methods drop out immediately. Others remain possible if you add structure (smaller size, written rules, a review cadence you will actually keep). A few fit cleanly. The output is a reading order for the method chapters, not an allocation.

You can sit between two profiles. The first pass is a working hypothesis. Fit Checks and your own behaviour over the next year refine it. It is not a life sentence.

What to do with this

Score yourself honestly on each lever before you open a method chapter. Write down the last time a position or a portfolio underperformed and what you actually did. That single note is more useful than any questionnaire.
