Capacity and tolerance

Chapter 8 of the mutual funds subject said the riskometer measures the scheme and not you. This chapter is the half it cannot measure, and it has two parts that people routinely merge.

Two different questions

Capacity — how much risk your circumstances can absorb. Objective, and computable from facts: your horizon, your income stability, your dependants, your obligations, your other assets.

Tolerance — how much risk you can live with. Psychological, and only partly knowable in advance.

A thirty-year-old with a secure salary, no dependants and a thirty-year horizon has high capacity. If a 20% fall would make them sell everything and stop investing for five years, their tolerance is low. Those two facts are both true and they imply different portfolios.

SEBI's guidance to investors makes profiling non-optional: always ask for your risk profiling before accepting advice, and insist the adviser works strictly from it. A recommendation made before anyone asked about your circumstances is not advice.

Estimating capacity

Five inputs, and the answer falls out of them.

Horizon. When is the money needed? Chapter 12 of the fixed income subject: money needed within about three years has almost no capacity for market risk, whatever your age.

Income stability. A tenured salary has far more capacity than commission income or a single-client business. Unstable income means both the emergency and the market fall can arrive together — chapter 6's correlation point, applied to your own life.

Dependants and obligations. A home loan and school fees reduce capacity, because the outgoings continue whatever markets do.

Other assets. Chapter 7: count the employer exposure, the property, everything.

Flexibility. Could you work two more years, or spend less for a while? Flexibility is capacity, and it is the input people forget they have.

Estimating tolerance, honestly

Harder, because the instrument most used is a questionnaire answered in a calm room.

"How would you feel if your portfolio fell 30%?" asked on a Tuesday afternoon produces an answer, and the answer is close to worthless. People overstate tolerance when nothing is happening and discover the real number during a fall.

Three better methods.

Use rupees, not percentages. "A 40% fall" is abstract. "₹18,40,000 gone from ₹46,00,000, with no idea when it stops" is the actual experience. Write the rupee figure for your own portfolio and sit with it.

Use your own history. What did you do in the last severe fall? Not what you think you would do — what you did. If you stopped a SIP or sold, that is data about you, and it is more reliable than any questionnaire.

Ask what you would do, not how you would feel. Feelings are not the problem; actions are. The question is whether you would sell, and chapter 9 showed that selling is what converts a fall into a loss.

The lower one wins

The rule this chapter exists for.

High capacity and low tolerance means a lower allocation than capacity alone would suggest. The theoretically optimal portfolio is not optimal if you will abandon it in year three, because an abandoned good plan returns less than a mediocre plan held.

Low capacity and high tolerance means a lower allocation too — the willingness to take risk does not create the ability to absorb it. This is the more dangerous mismatch, because it feels like courage.

So: allocate to the lower of the two. A portfolio you will hold is worth more than one you should theoretically own.

Tolerance can be raised, and capacity mostly cannot

A genuinely useful asymmetry.

Capacity is set by circumstances and changes slowly. You cannot decide to have a longer horizon.

Tolerance responds to structure, which is chapter 9's point: an emergency fund, a horizon-matched allocation, automation, a written plan, and looking less often. Each one reduces how much a fall demands of you, and together they can raise the allocation you are genuinely able to hold.

It also rises with experience. Somebody who has held through two severe falls and seen the recovery has evidence that the first-timer does not.

So the sequence over a lifetime is: build the structures, let tolerance rise with them, and move the allocation towards capacity as it does — rather than starting at capacity and discovering tolerance the hard way.

Reviewing it

Circumstances change, and the allocation should follow. A new dependant, a job change to variable income, a large loan, approaching retirement — each reduces capacity, and chapter 8's sequence risk means the last one matters most.

The one trigger that should not change the allocation is the market having moved. Raising equity after three good years, or cutting it after a fall, is chapter 9's behaviour gap with a justification attached.

The point

Capacity is what your circumstances can absorb and tolerance is what you can live with, and the allocation follows the lower of the two. Estimate tolerance in rupees and from what you actually did last time, not from a questionnaire. Capacity changes slowly; tolerance rises with structure and experience, which is the direction to work in.
