What should you do when the stock market drops?
For long-term money, keep investing on schedule and don't panic-sell. Money needed within 5 years shouldn't be in stocks.
New to this?
A stock market drop is when the prices of many company shares fall at once, often by 10%, 20% or more. If you own an index fund or a 401(k), its balance falls too. Drops happen regularly and nobody can predict them. What you do during one can matter more than which funds you picked.

Myth
The market is crashing, so I should sell everything before I lose it all.
Truth
Selling turns a drop on paper into a real loss. In the example, Priya's $20,000 falls to $15,000. If she sells, the $5,000 loss is locked in, and she has to guess when to buy back.
Worth memorizing
- 1
A loss is permanent only when you sell.
Until you sell, you still own the same number of shares. They are just priced lower for now.
- 2
Money for the next 5 years stays out.
Cash you need soon belongs in insured savings, so a drop never forces you to sell stocks at a low price.
- 3
Regular contributions buy more shares when prices fall.
The same $300 buys 4 shares at $75 but only 3 at $100. Stopping contributions during a drop gives that up.
If the money is for something 10 or more years away, I'd look at the balance less often during a drop, not more. Keep the automatic contributions running. If a drop costs you sleep, change your mix later, when things are calm.
Do this today
Write down each investment account and the year you expect to need that money. Move anything needed within the next 2 years to insured savings. Then confirm your automatic contributions are still on, and close the app.
Practice
1 of 3
Your fund falls from $50 to $40 a share. How many shares does $400 buy now, compared with before?
$400 ÷ $40 = 10 shares now, versus $400 ÷ $50 = 8 shares before. Regular contributions buy more shares when prices are lower.
2 of 3
When does a stock market drop become a permanent loss for you?
Until you sell, you own the same shares at a lower price. Selling turns the paper loss into a real one.
3 of 3
Which money should not be invested in stocks?
Money you need within about 5 years could be caught by a drop right before you need it. Keep it in insured savings or similar.
Tips
Check your timeline first
Ask when you will need this money. If it is 10 or more years away, today's drop matters less than it feels. If it is within a year or two, move that money somewhere safer.
Keep automatic contributions running
Leave your 401(k) and IRA contributions as they are. Every paycheck buys shares at the lower price, without you having to decide anything.
Look at your balance less
Turn off price alerts and skip the app for a few weeks. Checking daily makes it harder to stick with a plan you made when you were calm.
Protect your emergency fund
A drop sometimes comes with layoffs. Keep 3 to 6 months of essentials in insured savings so you never need to sell investments to pay rent.
A worked example: holding and buying through a 25% drop
Priya owns 200 shares of a stock index fund at $100 each. The price falls 25% to $75 and stays there for 6 months. She keeps investing $300 a month.
- The drop takes 200 × $100 = $20,000 down to 200 × $75 = $15,000. If she sells now, the $5,000 loss is real.
- She keeps going. $300 a month at $75 buys 4 shares, so 6 months adds 24 shares for $1,800. She owns 224 shares.
- This assumes the price later returns to $100, which is not promised. Then 224 × $100 = $22,400, which is $600 more than the $21,800 she put in.
- Value before the drop$20,000
- 25% drop−$5,000
- Value after the drop=$15,000
- 6 months of $300 buys+$1,800
- Value at the low=$16,800
- Shares she now owns224
- If the price returns to $100$22,400
- Total she put in−$21,800
- Ahead of what she put in=$600

Common mistakes
Stopping contributions during the drop
Pausing your 401(k) when prices are low means you skip buying at a discount, and you may also miss the employer match. Keep contributing if your budget allows it.
Keeping short-term money in stocks
A down payment or tuition bill due next year is the money a drop hurts most. Short-term goals belong in insured savings, CDs or Treasury bills.
Waiting for the all-clear to buy back
There is no signal that the drop is over. People who sell and wait for things to feel safe often buy back after prices have already risen.
Going deeper
When the stock market drops, the usual best move for long-term money is to do very little: keep your regular contributions going and don't sell in a panic. A loss only becomes permanent when you sell, so the real work is making sure money you need soon was never in stocks to begin with.
Drops are a normal part of investing
Stock prices have fallen sharply many times in US history, sometimes by a third or more, and nobody can reliably predict when. Owning stocks means living through drops. Past recoveries do not promise future ones.
Selling locks in the loss
When prices fall, you still own the same shares. If you sell, the loss becomes real and you need to pick a moment to buy back in. Getting both the exit and the return right is very hard.
Your timeline decides how much a drop matters
Money you won't touch for decades has time to wait. Money you need within about 5 years should not be in stocks, because a drop could arrive right before you need it.
Your plan should be set before the drop
Choose your mix of stocks, bonds and cash when markets are calm. Then a drop becomes a moment to follow the plan, maybe by rebalancing, instead of a moment to invent a new one.
What a drop means for your money
When the market falls, the price of each share you own falls. Your balance goes down even though you still own exactly the same number of shares. People call a fall of 10% from a recent high a correction, and a fall of 20% or more a bear market.
A broad index fund owns hundreds or thousands of companies. A single company can go out of business, but a fund holding the whole market would need most of the economy to fail to go to zero. That is why a diversified fund is easier to hold through a drop than a handful of single stocks.
Why selling in a panic hurts
Selling after a big fall feels like stopping the pain. The problem is that you then have to decide when to get back in, and there is no signal that tells you. Prices can rise sharply on days when the news still looks bad, so people who sell and wait for things to feel safe often buy back at higher prices than they sold for.
The SEC's investor education office puts it simply: most investment plans are built for the long term, and if you are able to, keep investing according to your plan even when the market swings.
What to do during a drop
First, check that your emergency fund is in place and that money you need within a few years is in savings, not stocks. If both are true, a drop can't force you to sell.
Second, keep your regular contributions going. Buying a fixed amount every month means you automatically buy more shares when prices are low. This is called dollar-cost averaging.
Third, look at your mix. A big drop in stocks can leave you holding fewer stocks than your plan calls for. Rebalancing back to your target means buying some stocks at the lower price, using new money or by moving some from bonds.
When changing course makes sense
Some changes are reasonable. If you realize you had money in stocks that you need next year, move what you need to savings, even at a loss, so a further fall can't hurt that goal. If the drop showed you that you can't live with the swings, plan a calmer mix with more bonds, and switch gradually once you've thought it through.
What to avoid is a big all-or-nothing move made in a single bad week. A choice you would not have made 6 months ago, when prices were higher, deserves a pause before you act on it.
If you are near retirement
A drop matters more if you need to start withdrawing soon. That is why many people move toward bonds and cash in the 5 to 10 years before retirement, and why target-date funds do this for you.
If you are already retired, keeping 1 to 2 years of spending in cash or short-term bonds can let you avoid selling stocks while prices are down. A fee-only financial planner can help you set this up.
Questions people ask
Should I stop contributing to my 401(k) when the market is down?
Usually no. Your contributions buy more shares at lower prices, and stopping can cost you the employer match. Pause only if you need the cash for essentials, and restart as soon as you can.
Is it a good time to buy when the stock market drops?
Nobody knows if a drop is over or just starting. Rather than trying to time it, keep investing on your regular schedule. If you have extra cash beyond your emergency fund, adding it on a set schedule spreads out your timing.
How long does it take the stock market to recover?
It has varied widely, from months to many years, and the past does not promise the future. That uncertainty is why money for goals in the next 5 years should not be in stocks.
Should I move my investments to cash until things calm down?
Moving everything to cash means you have to guess when to go back in, twice. If the drop showed you that you hold too much in stocks for your comfort, shift your target mix gradually instead.
