When markets crash, a pre-written bear market checklist ETF Europe is worth more than any analysis, because it replaces panic with a calm, pre-committed routine. The worst investment decisions happen in the heat of a downturn; a checklist made when you’re calm protects you from your fear-driven self. This guide is the bear-market checklist for European UCITS investors in 2026 — the steps to follow (and not follow) when everything is red.
I keep my own version of this checklist and re-read it during every downturn. The point is to act from the plan, not from the emotion. Here’s the checklist.
Why a checklist beats your judgement in a crash
A falling market is not a place where careful thinking happens. When a globally diversified portfolio drops 25% or 30% in a matter of weeks, the part of your brain that evolved to flee predators takes over from the part that reads spreadsheets. Heart rate climbs, sleep suffers, and the single most expensive instinct — “make it stop” — feels like wisdom. It isn’t. It’s the cause of most permanent losses, because a paper loss only becomes real when you sell.

A checklist works because it removes the decision from the moment of stress. Pilots and surgeons use them for exactly this reason: in a crisis, you don’t rise to the occasion, you fall to the level of your preparation. The checklist is your preparation. Across eleven years I have lived through the 2018 fourth-quarter slide, the 2020 COVID crash, the 2022 bond-and-equity double drawdown, and the volatility of 2025. The single behaviour that separated my good outcomes from my mistakes was whether I followed a written plan or improvised. Improvising lost me money every time.
The bear-market checklist
When markets are crashing and you feel the urge to do something, work through this list:
- Do nothing rash. The first rule. No selling, no panic moves. Sit on your hands for 24-48 hours before any decision.
- Re-read your investment plan. Your written allocation and “I will keep buying” rule, made when you were calm. Trust the calm version of yourself.
- Keep your automated contributions running. Your monthly DCA is now buying at lower prices — this is the opportunity, not the threat. See the DCA guide.
- Check your emergency fund, not your portfolio. Confirm you have cash for living expenses so you’re never forced to sell. See the emergency fund guide.
- Consider rebalancing (not selling). If your allocation has drifted, rebalancing means buying more of what fell — disciplined, not panicked. See the rebalancing guide.
- Stop checking your portfolio hourly. Constant monitoring amplifies fear. Check weekly at most during a crash.
- Zoom out. Look at a 20-year chart. Every past crash is a temporary dip on the long-term uptrend.
Work through the steps in order. The first three are about not destroying value; the last four are about positioning yourself to benefit once the recovery arrives — and it always has, eventually. If your asset allocation strategy was sound before the crash, the crash itself changes nothing about its logic.
Do this / don’t do that: the crash decision table
The fastest way to use a checklist under stress is a two-column “do / don’t” view. Print it, screenshot it, tape it inside a cupboard — wherever you’ll see it when the headlines turn red. The figures below are illustrative, chosen to show the shape of each decision rather than to predict any particular market.
| When the market falls hard | Do this | Don’t do that |
|---|---|---|
| Quality core holdings (broad world ETF) | Hold; keep buying the same fund monthly | Sell to “stop the bleeding” |
| Monthly contribution (e.g. €600) | Leave the standing order running — it buys more units cheaply | Pause it “until things calm down” |
| Allocation that has drifted 8–10% off target | Rebalance: sell what held up, buy what fell | Chase the exact bottom with a lump sum |
| Holdings sitting at a real loss in a taxable account | Consider tax-loss harvesting where your country allows it | Sell purely for the tax break and stay out of the market |
| Near-term spending (next 1–3 years) | Cover it from cash and short-term bond buffer | Fund it by selling equities at a 30% discount |
| Your portfolio screen | Check weekly at most; mute push alerts | Refresh the app hourly and doom-scroll |
If you take one thing from the table, take the middle two rows. Keeping the contribution running and rebalancing into weakness are the two actions that quietly convert a crash from a wealth-destroyer into a wealth-builder.
What NOT to do
- Don’t sell to “stop the bleeding.” Selling locks in the loss and misses the recovery — the best days cluster right after the worst.
- Don’t try to time the bottom. No one calls bottoms reliably. Keep buying steadily instead.
- Don’t abandon your plan. The plan was made for exactly this moment. The crash is the test, not a reason to change strategy.
- Don’t make leveraged bets to “recover faster.” Adding risk in a downturn often deepens the damage.
The market correction buying guide covers the opportunity side, and the panic-selling guide covers the psychology.
Worked example: rebalancing through a 30% drawdown
Theory is easy to nod along to and hard to follow when the numbers are red. So here is the arithmetic, step by step, with a simple two-fund portfolio. The figures are illustrative.
Suppose you start with a €100,000 portfolio at an 80/20 target: €80,000 in a global equity UCITS ETF and €20,000 in a short-term EUR bond ETF. A bear market then takes equities down 30% while bonds hold roughly flat.
| Holding | Before crash | After 30% equity fall | Weight now |
|---|---|---|---|
| Global equity ETF | €80,000 | €56,000 | 73.7% |
| Short-term bond ETF | €20,000 | €20,000 | 26.3% |
| Total | €100,000 | €76,000 | 100% |
Your portfolio is now €76,000 and the equity weight has slipped from 80% to 73.7%. To return to 80/20, equities should be 80% of €76,000 = €60,800, and bonds €15,200. So you sell €4,800 of the bond ETF (which held up) and buy €4,800 of the equity ETF (which fell). That single trade nudges you back to target — and, crucially, it forces you to buy equities precisely when they are 30% cheaper, which is the disciplined opposite of panic.
You can model the long-run effect of those cheaper units with the compound growth calculator, and sketch the target weights themselves with the ETF portfolio builder. The point of the worked example is not the exact figures — it’s that rebalancing turns a frightening number into a mechanical, almost boring instruction.
Tax-loss harvesting: a quiet upside of the downturn
If you hold ETFs in a taxable account and some sit at a genuine loss, a crash can hand you a tax benefit. In many European jurisdictions you can realise a capital loss to offset capital gains — sometimes in the same year, sometimes carried forward — by selling the losing position and reinvesting in a similar-but-not-identical fund so you stay invested. The rules differ sharply by country, and some (Germany’s loss pots, for instance, or wash-sale-style restrictions elsewhere) have specific catches, so this is a “check your own jurisdiction” step rather than a universal rule.
The mechanics matter: harvest the loss, but do not exit the market. Swapping one broad world ETF for another tracking a comparable index keeps your exposure intact while booking the loss. Done carelessly — selling and waiting to “buy back lower” — it becomes market timing in disguise. The dedicated tax-loss harvesting guide walks through the European specifics.
Check the buffer before you check the price
The reason most investors are forced into selling at the bottom is not stupidity — it’s cash flow. A redundancy, a broken boiler, or a tax bill arrives, the bank account is thin, and the only liquid asset left is a portfolio that’s down 30%. That’s how paper losses become permanent. The defence is built before the crash, not during it.
So step four of the checklist is deliberately about the buffer, not the portfolio. Confirm that your cash reserve plus any short-term bond holding covers your near-term spending — ideally the next one to three years of essentials and any known large outlays. If it does, the equity drawdown is simply weather you can sit out. If it doesn’t, that’s the genuine problem to solve, and the emergency fund versus short-term bond ETF comparison shows how to size and structure it.

Common mistakes
- Pausing the standing order. Switching off your monthly contribution feels prudent and is the opposite — it cancels the automatic discount the crash is offering you.
- Going to 100% cash to “wait for clarity.” Clarity arrives only after the recovery is well underway, by which point you’ve missed the best days. The market never rings a bell at the bottom.
- Rebalancing on emotion instead of bands. Decide in advance that you rebalance when a holding drifts (say) 5% off target — not when a red day makes you anxious.
- Confusing volatility with risk. For an accumulator a decade from needing the money, a 30% drop is volatility, not loss. Real risk is being forced to sell, or abandoning the plan.
- Tinkering for the sake of action. The urge to “do something” leads to switching funds, adding leverage, or chasing themes. The disciplined response usually looks like inaction plus your normal contribution.
Key takeaways
- Write the checklist while you’re calm; it exists to overrule your fearful self in the moment.
- Keep buying — your monthly DCA turns a crash into a discount, automatically.
- Rebalance into weakness: sell what held up, buy what fell, back to your target weights.
- Check the emergency and bond buffer before you check the price, so you’re never a forced seller.
- Consider tax-loss harvesting where your country allows it — but stay invested while you do.
FAQ
Q: What should I do when the market crashes?
A: Follow a pre-written checklist: do nothing rash, re-read your plan, keep contributions running, confirm your emergency fund, consider rebalancing (buying), reduce monitoring, and zoom out. Act from the plan, not the panic.

Q: Should I sell during a bear market?
A: No — selling locks in losses and misses the recovery (the best days cluster after the worst). For an accumulator, a crash is a buying opportunity.
Q: Should I buy more during a crash?
A: Your automated DCA already is, at lower prices. If you have spare cash beyond your emergency fund, adding more (or rebalancing) is reasonable — but don’t try to time the exact bottom.
Q: How often should I check my portfolio in a downturn?
A: Weekly at most. Hourly checking amplifies fear and the urge to sell. Less monitoring leads to better decisions.
Q: What if this crash is “different”?
A: Every crash feels different in the moment, yet markets have always recovered. Your plan accounts for crashes; trust it rather than the “this time it’s different” voice.
Q: How do I rebalance during a bear market?
A: Compare each holding’s current weight to its target. Sell a slice of whatever held up (often bonds or cash) and buy the asset that fell, until you’re back at target. In a 30% equity drawdown that means buying equities while they’re cheap — disciplined, not reckless.
Q: Should I stop my monthly contributions when the market is falling?
A: No. Pausing contributions removes the biggest advantage you have in a crash — buying more units at lower prices. Leave the standing order running unless your income itself has genuinely stopped.
Q: Is tax-loss harvesting worth it for a European UCITS investor?
A: It can be, in a taxable account, if you have realised gains to offset and your country permits it. Sell the losing fund, reinvest in a similar one to stay invested, and check the local rules carefully — the treatment varies a lot across the EU.
Q: How much cash should I hold so I’m not forced to sell?
A: Enough to cover near-term essential spending and any known large bills — commonly one to three years’ worth across cash and a short-term bond ETF. With that buffer in place, an equity drawdown becomes something you can simply wait out.
Q: How long do bear markets usually last?
A: There’s no fixed answer, and the length matters less than your behaviour. Historically markets have recovered and gone on to new highs; the investors who did best were those who kept contributing and didn’t sell, however long the trough lasted.
The bottom line
For a European investor in 2026: a pre-written bear-market checklist replaces panic with a calm routine when everything is red. The steps: do nothing rash, re-read your plan, keep contributions running (they’re buying cheap), confirm your emergency fund, consider rebalancing, stop checking hourly, and zoom out. What not to do: sell, time the bottom, abandon the plan, or add leverage. The crash is the test your plan was built for. The bull-market discipline guide covers the opposite challenge, and the market correction buying guide covers the opportunity.
