What to do in a market crash (usually, nothing)

The investors who outperformed over 36 years weren’t the smartest. They were the calmest.

We’ve been through four serious market crashes since starting Invest Drive in 1988 — the 1992 Harshad Mehta scandal, the dot-com burst in 2000, the global financial crisis in 2008, and the COVID-19 crash in 2020. Each one felt unprecedented at the time. None of them turned out to be permanent.

The clients who built the most wealth over those 36 years weren’t the smartest. They weren’t even the best stock-pickers. They were the calmest. Here’s the playbook we share with our clients when markets fall hard.

Step 1: Stop checking your portfolio every day

The first and most powerful intervention is to check your portfolio less often, not more. When markets fall, the temptation is to check three times a day “to know what’s happening.” This is exactly backwards. You’re not going to make better decisions by being more anxious.

If your plan was sound when you made it (six months ago, when markets were calm), it’s still sound. Daily checking adds nothing but stress.

The investors who built the most wealth over four crashes weren’t the smartest. They were the calmest.

Step 2: Do nothing

For most investors most of the time, the right action during a market crash is no action. Specifically:

  • Don’t stop your SIPs. The single biggest mistake we see. Falling markets are when SIPs do their best work — you’re buying more units per rupee.
  • Don’t sell out of equity into “safety.” You’re locking in a temporary loss as a permanent one.
  • Don’t switch fund managers. Don’t punish a fund for being down 25% when the whole market is down 25%.
  • Don’t time the bottom. No one calls bottoms. The recovery is usually faster and sharper than the fall.

From 2008 to 2024, the Sensex went from 21,000 (Jan 2008 peak) to 75,000+. But if you missed just the 10 best days during that period, your return would have been less than half. The best days clustered tightly around the worst days. Staying invested means staying in.

Step 3: Rebalance, if you have a plan in place

This is the only “action” we recommend, and only if you have a target asset allocation. If your plan was 60% equity / 40% debt and the equity portion is now down to 50%, you sell some debt and buy more equity to restore the 60-40 mix.

This sounds counterintuitive — buying more of what’s falling — but it’s mathematically rebalancing back to your original plan. Over a full cycle, it adds 50-100 basis points to your annual return.

Don’t do this freelance. Do it with a written plan and a quarterly or semi-annual cadence.

Step 4: If you have spare cash, deploy it gradually

If you have idle savings (an emergency fund excess, a bonus, a recent inheritance) — and your existing plan is on track — a market crash can be a good time to deploy that cash. Two rules:

  1. Don’t deploy all at once. Spread it over 6-12 months via a Systematic Transfer Plan (STP) from a liquid fund into equity funds. Trying to call the bottom usually fails.
  2. Don’t deploy money you’ll need in under 5 years. Even at the “bottom,” equity can fall further before recovering.

Step 5: Recognise what you can’t control

Markets, geopolitics, inflation prints, RBI rate decisions, US Fed announcements — you can’t control any of these. What you can control:

  • Your savings rate
  • Your asset allocation
  • Your costs (expense ratios, transaction fees)
  • Your tax efficiency
  • Your behavioural response

Spend your mental energy on those five. They compound over decades. The rest is noise.

The hardest part

The hardest part of all this isn’t intellectual — it’s emotional. When your ₹50 L portfolio falls to ₹35 L over six months, “stay the course” sounds easy in a blog post but feels terrible in real life.

That’s why having an advisor matters more during crashes than during bull markets. Our job in good times is to set up sensible plans. Our job in bad times is to be the steady voice that says: “Yes, this is uncomfortable. No, you should not sell. Yes, you will look back on this in 5 years and be glad you held.”

We’ve had that conversation hundreds of times across 36 years. It’s almost always been right. The handful of times clients overrode us and sold during a crash, they almost always regretted it — and a few never re-entered equity at all, missing the full recovery.

A simple test

If a market crash is making you lose sleep, the problem usually isn’t the market. The problem is that your asset allocation was too aggressive for your true risk tolerance. The fix isn’t to sell now — it’s to rebalance gradually toward something you can live with, and then to stay there through the next cycle.

Your portfolio should let you sleep at night. If it doesn’t, that’s a planning conversation worth having — preferably before the next crash, not during.
