Everyone plans to hold through a downturn. Far fewer do, because a 30% fall arrives as headlines rather than as a statistic.
Decide now, because you will not decide well later
Everyone agrees they will hold through a downturn. Far fewer do, because a 30% decline does not arrive as a statistic — it arrives as headlines, as a number in an app, and as a very reasonable-sounding argument that this time is structurally different.
The single most useful thing you can do about a crash is write down, in advance and while calm, what you will do when one happens. Then follow the note rather than the feeling.
Selling converts a fluctuation into a loss
While you hold, a decline is a price. It becomes a permanent loss only when you sell.
And the damage is not just the sale. It is that you then have to decide when to return — and people who sell in a panic overwhelmingly re-enter after the recovery is visible, which means they took the entire fall and missed a large part of the rebound. The best days in a market tend to cluster very close to the worst ones, so being absent for a few weeks can cost years of return.
The market pays a premium for enduring exactly the moments that make you want to leave.
The mechanic that helps: keep buying
If you contribute monthly, a crash means your regular contribution buys more shares for the same money. That is not a consolation prize — it is a large part of where long-run returns come from for someone still accumulating.
Automatic contributions are valuable here precisely because they remove the decision. Nobody feels enthusiastic about investing during a crash, which is why it works better when nobody has to feel anything.
What to actually do, in order
- Check your timeline, not the news. Money you need within a couple of years should never have been exposed. If it was, that is the mistake to fix — carefully, not in a panic.
- Confirm your emergency fund is intact. The real risk in a downturn is being forced to sell because you lost income. Cash reserves are what stop a market problem becoming a personal one.
- Keep contributing. Change nothing about the schedule.
- Rebalance if your allocation has drifted — which mechanically means buying what fell. Uncomfortable, and that is rather the point.
- Stop looking daily. Checking a portfolio during a decline produces anxiety and no information you can act on.
The advice changes, because you no longer have decades to recover and you may be selling to eat. This is what a cash and bond buffer is for: enough to fund a few years of spending so you never have to sell stocks into a fall. If you are within five years of drawing down and have no such buffer, that is worth addressing in a normal market rather than a bad one.
Things that sound smart and are not
- "I will get back in when it settles." It never feels settled at the bottom. That is what a bottom is.
- "I will move to cash until this passes." This requires being right twice — when to leave and when to return — and the second is harder than the first.
- "It is different this time." Sometimes the cause genuinely is novel. The behaviour of markets over long periods has not been.
The honest caveat
Nothing guarantees recovery on any particular timetable. Broad markets have recovered from every historical decline eventually, but "eventually" has occasionally meant many years, and no individual company or country is promised anything.
Which is the argument for being broadly diversified and for only investing money with a long horizon — not the argument for trying to dodge the falls. This is educational content, not investment advice.
