Every January, a client forwards us a market outlook. Sometimes from a brokerage, sometimes from a newspaper, most often from a WhatsApp group. The question attached to it is always a version of the same one: does this change what I should do?
Almost always, no.
Not because the outlook is wrong. Some of them turn out to be right. A forecast is simply the wrong instrument for the job. A forecast is a claim about the world, and what determines your outcome is a claim about yourself: what you will do when the number on the screen is thirty per cent lower than it was.
We would rather spend our time on the second claim. We call those guardrails.
What a Guardrail Is
Think of the railing on a ghat road. It does not pick your route, it does not drive the car, and on every ordinary journey you never touch it. It exists for the one moment when you would otherwise go over the edge.
A guardrail in a portfolio works the same way. It is a rule you write down while you are calm, which constrains what you are allowed to do when you are not.
That is the whole idea. It is unglamorous, and it predicts nothing. A guardrail does not need to know whether a correction is coming. It only needs to exist before the correction arrives, because the one thing we can say with confidence is that you will not be thinking clearly in the middle of one. Nobody is. The reason to write the rule early is that the person who writes it and the person who has to follow it are, in a meaningful sense, two different people.
The market does not care what you decided in advance. You will.
The Four We Actually Use
Every client’s set looks different, because the constraints that matter depend on what the money is for and when it is needed. But four show up in almost every plan we write.
None of what follows is a recommendation to you. Which of these belong in your own plan, and at what levels, depends on facts about you that a blog post cannot know.
An allocation band, with a rebalancing trigger. We write these as a band rather than a single target. If equity is meant to be 60 per cent of a portfolio, the rule says what happens when it drifts to 70 or falls to 50, and it says it as an action rather than an intention. Rebalancing is the rare discipline that forces you to sell what has run and buy what has not, at exactly the moment your instincts argue for the opposite. Its value to us is not that it raises returns, and we make no claim that it does. Its value is that it is mechanical, so it survives the moment when judgement does not.
A reserve that sits outside the portfolio. We size these in months of actual expenses rather than in rupees. The point of the reserve is not return. It is that it removes the most destructive reason anyone ever sells an investment, which is needing the money this week. In our own experience, the permanent losses we have watched careful investors take have usually started with a liquidity problem somewhere else in their life, not with the investment itself.
A written sell policy that does not mention price. Most people cannot say, in advance, what would make them sell something. So when it falls, the fall itself becomes the reason, which is circular, and which is how a temporary decline gets converted into a permanent loss. In the policies we help write, the conditions are the ones that would genuinely invalidate the original decision: a change in the mandate, a change in your own goal or time horizon, a rebalancing trigger. Price is not on that list.
A cooling-off rule. Any unscheduled change waits seventy-two hours and requires one conversation. This is the least sophisticated of the four and probably the most useful. A great many decisions that feel urgent on a Monday evening are simply gone by Thursday.
Why It Has to Be Written
A guardrail you only hold in your head is not a guardrail, because memory is obliging. Under stress it quietly revises what you decided into whatever you want to do now, and it feels like consistency while it does it.
So the rules go into a document, dated, in the client’s own words wherever possible.
When markets fall and a client calls, our first move is not to offer a view on the fall. It is to read their own rules back to them. That conversation is easier than one starting from a blank page, and it is easier precisely because the client wrote the page.
What Guardrails Do Not Do
They do not prevent losses. Nothing does. A diversified portfolio in a falling market falls, and no amount of process changes that arithmetic.
They do not improve returns directly, either.
What they do is narrow the range of things you might do badly. They remove the unforced errors: the panic sale near the bottom, the concentrated bet taken after a good year, the plan abandoned in month eight of an eighteen-month rough patch. Over a long enough period, our experience is that avoiding those errors matters more than most of the decisions people agonise over. We cannot prove that to you, and we would be sceptical of anyone who claimed they could.
They are also not a substitute for the portfolio being appropriate in the first place. A well-guarded allocation that was wrong for your goals is still wrong for your goals.
The Point
We are not in the business of telling you where the market is going. We do not know, and we are sceptical of people who say they do.
What we can do is help you write down, while nothing is going wrong, what you intend to do when something does, and then hold you to it. The objective is not to be right about the next twelve months. It is to still be invested at the end of them, on terms you chose yourself.
