What a Market Drawdown Reveals About Your Real Risk Capacity

The measurement Kabir keeps failing to take

Kabir has been through three significant falls and held on each time, which he takes as settled evidence about his temperament.

What he cannot tell you is what the third one was actually like. He remembers holding, and he remembers being right. He does not remember checking the portfolio eleven times on a Tuesday, or the fortnight of poor sleep, or the afternoon he came close to moving a large part of it to cash and talked himself out of it for reasons he can no longer reconstruct.

The recovery edited the memory, which is what recoveries do. And because it did, the most valuable information he has ever had about his own investing was collected and then lost, three times.

The only honest test is the involuntary one

Before a fall, risk tolerance is a claim. During one, it is an observation.

This is not a criticism of investors. Predicting your own reaction to a loss is genuinely hard, because imagining a number going down and watching your savings shrink while the news explains why it will continue are different experiences. People who answer a risk questionnaire honestly still routinely discover, in the event, that the honest answer was wrong.

Which makes a drawdown unusually valuable. It is the one moment when the information you most need about yourself is available for free — and the one moment when nobody wants to look at it.

What to notice while it is happening

The instinct is to avoid thinking about the portfolio at all, which wastes the measurement. A few things are worth observing deliberately, at the time.

Whether you are checking more often is one of the better indicators, because somebody looking at their portfolio several times a day is not gathering information — there is no decision new data would change — they are managing anxiety, and it is not working.

Whether it is affecting anything outside your finances is the next: sleep, temper, concentration at work, snapping at people. A portfolio costing you those things is too aggressive for you regardless of what any capacity calculation says.

What you are telling yourself you might do matters more than what you have done. "I'll just move it to cash until things settle" is the thought preceding the action, and noticing it as a thought is what gives you the chance to examine it. Watch too for whether you are looking for permission — searching for articles predicting further falls, or asking people until somebody agrees with you, is usually a decision already made and looking for cover.

And ask whether you would buy more at these prices, which separates two things that otherwise feel identical. A calm no because there is no spare money is fine. A flinch means the allocation is above your tolerance.

Write it down while it hurts

The single most useful thing to do in a drawdown is record it, because the memory will not survive the recovery.

After markets rise, people misremember how they felt. The fall becomes an obvious buying opportunity in hindsight, the fear compresses into a footnote, and the lesson is lost — which is exactly why Kabir can be surprised by his own reaction in a fourth crash despite having been through three.

So write down, at the time: the date, roughly how far the portfolio has fallen, what you are feeling, what you are tempted to do, and what you actually did. A few sentences. It takes minutes and it is the highest-quality data you will ever have about your own investing behaviour.

Then read it before you next change your allocation.

What the reaction tells you, and what it does not

If you did nothing and slept fine, the allocation is within tolerance — noting that this is evidence about this fall, since a deeper or longer one may find a different limit, and a fall coinciding with losing your job is a different test entirely.

If you did nothing but it cost you a great deal, that is a warning rather than a pass, and it is the most commonly ignored result because the outcome looked fine. Holding on through gritted teeth works until the one time it does not, and the one time is expensive.

If you sold, the important thing is accuracy rather than shame. You have learned your actual limit, which is more than most investors know. The mistake would be concluding you should never hold equity again; the correct conclusion is that you were holding more of it than you could carry, which is a fixable arrangement.

And if you bought more, check that it was planned rather than exciting. Buying into a fall because it fits a rule you wrote earlier is discipline. Buying because it feels like a bargain is a different activity that happens to look similar.

What capacity looks like when it is genuinely low

Some of what a drawdown reveals is not psychology at all. It is structure, and it matters more.

If the fall coincided with worry about your job, you learned that your income and your portfolio are exposed to related conditions, which is a real reduction in capacity that no questionnaire asks about. If you had to sell something to cover an expense, you learned your emergency fund is too small — and being a forced seller during a fall is the single most damaging thing that can happen to a long-term investor, which is a cash-management problem rather than an investing one. If a goal moved closer while the market fell — a house purchase, a fee payment — you learned that money with a near-term job was sitting in a long-term asset.

Each of those has a fix that is not "hold fewer equities": more cash, more insurance, matching each pool of money to when it is needed.

What to change afterwards, and when

Change it after the recovery, not during the fall.

Reducing risk at the bottom converts a temporary loss into a permanent one and then leaves you deciding when to return — a second decision, at least as hard as the first, and usually made badly. If the allocation is wrong it will still be wrong in a year, and it can be fixed from a position that does not lock in the damage.

The exception is a structural problem: no emergency fund, or money needed soon held in equities. Those should be addressed as soon as you can, because they are not about market levels.

When you do adjust, adjust to what you observed rather than to what you now feel. The note you wrote at the time is the record; the feeling you have after a recovery is not.

What to take away

A drawdown is unpleasant and it is also the only genuine measurement of your risk tolerance you will ever be offered. Take the reading while it is available.

Watch how often you check, whether it is leaking into the rest of your life, and what you are tempted to do. Write it down at the time, because the recovery will edit your memory. Separate what the fall revealed about your temperament from what it revealed about your structure — the second is usually more fixable and more important. And make the changes once it is over, not while the evidence is still falling.
