When markets fall 20–30% in a short time, it rarely feels like a “buying opportunity.” It feels like a crisis.
Your portfolio is flashing red. Headlines scream “bloodbath” and “meltdown.” WhatsApp groups are full of panic. The temptation to “do something” right now is overwhelming.
History and behavioural‑finance research both show that what investors do during crashes often matters more than what they held before the crash. Those who panic‑sell, go to cash and wait for “clarity” often miss the recovery. Those who stay disciplined—or even lean in carefully—tend to come out ahead over full cycles.
Here are three concrete moves to make when (not if) the market plummets.
Move 1: Pause, Protect Your Foundation, and Don’t Panic‑Sell
The first move in a crash is not to buy the dip. It’s to stop yourself from making a permanent mistake out of temporary fear.
Understand your brain is wired to panic
Research on past crashes—from 1987 to the dot‑com bust, 2008 and COVID—shows that investors consistently:
- Overreact to short‑term price moves
- Follow the herd (sell because “everyone is selling”)
- Move to cash and then struggle to re‑enter, missing much of the recovery
A recent review of investor behaviour in crashes highlights the same patterns: herd behaviour, loss aversion, recency bias and the need for control all push people to sell at the worst possible times.
Knowing this doesn’t remove fear, but it helps you name it: “This is my crash‑brain talking.”
Secure your safety net first
Before worrying about trades, make sure your foundation is intact:
- Emergency fund: Ideally 6–12 months of essential expenses in safe, liquid instruments (savings account, short‑term debt, liquid funds).
- High‑cost debt: If you’re over‑leveraged (personal loans, margin, F&O positions you don’t fully understand), priority one is to reduce fragility. Forced selling in a crash is how temporary drawdowns become permanent losses.
- Cash‑flow visibility: If your job or business is vulnerable to a recession, be conservative; you may need that buffer.
You don’t want to be in a position where you are forced to sell quality assets at distressed prices to pay EMIs or expenses.
What not to do in the first 48 hours
- Don’t liquidate your long‑term portfolio just because the index is down sharply.
- Don’t check your portfolio every 10 minutes. That only amplifies anxiety.
- Don’t take big leveraged “revenge bets” to recover losses quickly.
Step one is simple and hard: do less than you feel like doing. Give yourself a cooling‑off period before any major decision.
Move 2: Keep (or Start) Systematic Investing Through the Downturn
Once your foundation is secure and you’ve avoided panic‑selling, the second move is to keep your investment engine running—and, if possible, take advantage of lower prices.
Why stopping SIPs usually hurts you
Systematic investing (SIPs / dollar‑cost averaging) is designed for exactly this scenario:
- You invest a fixed amount at regular intervals, buying more units when prices are low and fewer when prices are high.
- Over time, this lowers your average cost per unit and smooths out volatility.
Multiple analyses show that:
- Dollar‑cost averaging helps investors stay invested, avoid emotional timing errors, and benefit from recoveries after volatile periods.
- For long horizons (20–40 years), disciplined periodic investing can outperform even perfectly timed “buy the bottom” strategies in many historical scenarios, because perfect timing is almost never achieved in real life.
In Indian data too, investors who continued SIPs through the COVID crash in 2020 saw strong gains in 2021–22, while those who stopped or redeemed often missed a large part of the rebound.
When a crash can actually help your long‑term returns
Think of it this way:
- If you believe equity markets will be higher 10–15 years from now, temporary crashes are times when you’re effectively buying future earnings at a discount.
- Your SIPs are quietly accumulating more units at lower prices, which helps when markets eventually recover.
Of course, if your income has been hit or your risk tolerance has fundamentally changed, you may need to adjust amount or asset mix. But in general:
- For long‑term goals (retirement, children’s education in a decade), continuing SIPs through crashes is usually the rational move.
- Stopping SIPs just because markets are falling is like refusing to buy more of your favourite product when it’s on sale.
Practical steps
- Don’t pause SIPs by default. Only adjust if your cash‑flow situation truly demands it.
- If your financial situation is strong and your asset allocation allows, consider modestly increasing SIP amounts during deep drawdowns.
- Automate as much as possible to reduce the urge to micro‑manage entries.
The goal is not to “catch the bottom.” It’s to keep compounding through the bottom.
Move 3: Rebalance and Upgrade Quality, Not Your Risk
The third move during a crash is more strategic: use the volatility to realign your portfolio with your long‑term plan.
Rebalance back to your target mix
If you had a sensible asset allocation before the crash—say, 60% equity / 40% debt or any mix suited to your risk profile—then:
- A market plunge likely dragged your equity weight below target.
- Rebalancing means selling a bit of what held up (often debt / gold) and buying enough equity to get back to your target percentage.
Long‑term studies of classic 60/40 portfolios show:
- Diversified portfolios experience shallower drawdowns than 100% equity, and
- They often recover faster from crashes, precisely because bonds or other defensive assets can be used to rebalance into cheaper equities.
- Over the past 150 years, a 60/40 portfolio experienced about 45% less “pain” (depth and duration of losses) than an all‑equity portfolio during major crashes.
The exact mix for you may differ, but the principle is the same:
Don’t abandon diversification in a crash. Use it.
If you never had an allocation plan, a crash is a good (if uncomfortable) time to define one, so you’re not just reacting to every market move.
Use the crash to upgrade quality
Crashes don’t just pull everything down uniformly. They often:
- Hit weaker, speculative names harder and sooner
- Drag quality companies down for temporary, sentiment‑driven reasons
Instead of:
- Doubling down on the riskiest, most beaten‑down names just because they’re “cheap”, or
- Blindly averaging every loser,
focus on upgrading the quality of your portfolio:
- Increase exposure to strong balance sheets, consistent cash‑flows and market leaders that you understand.
- Reduce or exit positions where:
- The original thesis is broken
- Governance concerns have emerged
- You realise you never properly understood the business
A crash can be an opportunity to swap weak exposure for strong exposure at more attractive valuations, without increasing your overall risk.
Check that your risk level still matches your life
Finally, be honest:
- If a 25–30% drawdown has made you sleepless to the point of wanting to sell everything, it may be a sign your equity allocation was too high for your real risk tolerance.
- Once markets stabilise (not in the eye of the storm), consider gradually adjusting your long‑term mix so you can stick with it through future volatility.
A good portfolio is not just one that looks good on Excel. It’s one you can actually live with in bad times.
Putting It All Together: A Simple Crash Playbook
When the next major sell‑off comes—and it will—having a pre‑decided playbook helps you act calmly when others are panicking. A concise checklist:
- Pause and protect your base
- Don’t panic‑sell your long‑term core holdings.
- Make sure emergency funds and leverage are under control.
- Keep your systematic investing going
- Maintain or modestly increase SIPs / DCA into diversified equity funds if your finances allow.
- Remember: you’re buying more units at lower prices.
- Rebalance and upgrade
- Rebalance back to your target asset allocation.
- Use the crash to move from weak, speculative holdings into higher‑quality assets without raising overall risk.
Crashes are never pleasant in real time. But history, data and behavioural research all point in the same direction:
- Investors who stay disciplined, keep investing systematically and rebalance thoughtfully tend to come out stronger on the other side.
You can’t control when the market will plummet. You can control how prepared you are—and how you respond when it does.
