How to Handle a 20% Market Fall Without Panic Selling

Market falls are uncomfortable, and they are also normal. Investors who stay in the market for long enough will go through several. The ones who do well are not those who feel nothing. They are the ones who decided what to do before the fall began.

Where the Indian market stands

The Nifty 50 reached a record of 26,373.20 on 5 January 2026. By 5 October 2026 it was near 22,500, about 15 percent below that peak. A 20 percent fall from the same high would put it near 21,100. Going further back, the Nifty fell about 38 percent in the Covid crash of early 2020 and regained its earlier high within roughly a year. In 2008 it fell about 60 percent and took around three years to get back. These are approximate figures from index history, and every fall had its own causes. What they show is that large falls happen, and recoveries, when they come, take time.

What the fall does to you

A falling portfolio is hard to look at. The pain of a loss tends to feel stronger than the pleasure of an equal gain, a pattern described in our note on loss aversion. The mind starts to look for a way to stop the pain, and selling is the quickest way. That is why decisions made in a fall are often poor ones: they are driven by relief, not by reasons.

Three questions before any sale

• Has the reason I bought changed? A lower price alone is not a reason. A broken business is.
• Do I need this money soon? Money needed within a few years should not have been in shares. If it is, that is a plan problem to fix, calmly.
• What was my plan? If you wrote an exit level or a review date, follow it. If you did not, a fall is a bad time to start improvising.

If you can answer all three and still want to sell, it is a decision. If you cannot, it is probably panic.

Prepare in calm

The best protection is an if-then plan written while the market is quiet. For example: if my portfolio falls 15 percent, I will review each holding against its reason. If it falls 25 percent, I will not add new money until I have finished the review. If a holding breaks its exit level, I will exit it, whatever the rest of the market does. Write the plan down and keep it where you can see it. Our note on drawdown maths explains how to set a personal limit.

Part of the plan should be about cash. Keep the money you expect to need over the next two or three years outside shares, in safe instruments. Then a fall in the market cannot force you to sell shares at low prices to pay a bill, and you can sit through the decline with a calmer mind.

SIPs during a fall

A SIP keeps buying through falls, which means it buys more units at lower prices. That feels wrong while it is happening, and many people stop their SIPs near the lows, which defeats the design. If your income is stable and your emergency fund is intact, continuing the SIP is the plan doing its job. If your income is under strain, reduce the amount before you stop it.

What not to do

• Do not check your portfolio every hour. It raises anxiety and changes nothing.
• Do not try to buy the exact bottom. Nobody calls it reliably, and waiting for certainty usually means missing the recovery.
• Do not borrow to buy the dip. A leveraged position can be forced out before the recovery arrives.
• Do not size up to win losses back, which is the pattern in revenge trading.

Common questions

Should I sell before it falls further?

No one can know where the low is. If your plan has an exit rule, follow it. If it does not, selling out of fear usually locks in a loss at a poor moment.

How long do falls last?

There is no fixed pattern. Some recover in months and some in years, as the examples above show.

Is a fall a buying chance?

It can be, for investors with cash set aside and a plan. It is not a reason to buy everything or to spend money you may need.
