What Doosol Points Out
- A stock market crash feels like the end of the world — but historically, every single crash has been followed by a recovery. Every. Single. One.
- The S&P 500 dropped 37% in 2008, 34% in 2020, and nearly 20% in April 2025 after tariff announcements. It recovered every time.
- The people who lost the most money weren’t the ones who stayed invested. They were the ones who panicked and sold at the bottom.
- If you’re investing for 10+ years from now, a stock market crash is a sale — not a disaster.
- This article isn’t about predicting when the next crash happens. It’s about what to do (and what NOT to do) when it does.
Your portfolio is down 15%. The news says “worst week since 2020.” Your coworker just sold everything and moved to cash. Your mom texted you an article titled “IS THIS THE END?”
Take a breath. We’ve been here before.
A stock market crash is terrifying — especially if you’re new to investing and watching your money shrink in real time. But here’s what nobody tells beginners: the crash isn’t what destroys your wealth. Your reaction to the crash is.
Let me show you what I mean.

First: What Counts as a Stock Market Crash?
Not every bad day is a crash. Wall Street has specific terms for this:
Pullback: A 5-10% decline from a recent high. This happens multiple times a year. Totally normal. Like rain in April — annoying but expected.
Correction: A 10-20% decline. This happens roughly every 1-2 years. Uncomfortable, but still part of the regular cycle.
Crash/Bear market: A 20%+ decline. This is the scary one. It happened in 2008, 2020, and briefly in 2022. These are rarer — maybe once every 7-10 years.
Right now in 2026, the S&P 500 is about 5% below its January all-time high. That’s a pullback — not even a correction yet. But with tariff uncertainty, rising oil prices, and geopolitical tensions, people are nervous. That’s exactly when you need a plan.
5 Things to Do During a Stock Market Crash
1. Do Nothing (Seriously)
This sounds like lazy advice. It’s actually the hardest and most profitable thing you can do.
Here’s the data: if you invested $10,000 in the S&P 500 at the absolute worst moment — right before the 2008 crash — and did nothing, your money would have grown to over $50,000 by 2026. You would have ridden through a 37% drop and come out 5x richer on the other side.
The people who lost money in 2008? They sold at the bottom. They locked in their losses and missed the recovery. “Doing nothing” isn’t passive — it’s a deliberate strategy that beats panic selling 100% of the time in historical data.
2. Keep Investing on Schedule
If you’re putting $200 or $500 into your portfolio every month, don’t stop. During a stock market crash, you’re buying the same investments at a discount. This strategy has a name: dollar-cost averaging (DCA).
Think of it like grocery shopping. If your favorite cereal goes on sale from $5 to $3, you don’t stop buying cereal. You buy more. Stocks work the same way — you’re getting more shares per dollar when prices are low.
The catch? It feels terrible. Every contribution feels like throwing money into a fire. But mathematically, buying during a crash is one of the best things you can do for your long-term returns.
3. Don’t Check Your Portfolio Every Hour
This one is psychological but real. Every time you open your brokerage app during a stock market crash, you see red numbers. Red numbers trigger fear. Fear triggers the urge to sell. Selling locks in losses.
The fix is simple: check your portfolio once a week, or even once a month. You wouldn’t check the price of your house every day — why do it with your stocks?
If you need to, delete the app from your phone for a week. I’m serious. The market will still be there when you come back.
4. Review (Don’t Change) Your Allocation
A stock market crash is a good time to review your portfolio — not to blow it up. Ask yourself:
Am I diversified enough? If 90% of your portfolio is in one sector (like tech), a crash will hit you harder than someone with a mix of stocks, bonds, and international exposure. An S&P 500 ETF like VOO gives you 500 companies across every sector — that’s built-in diversification.
Is my timeline still long? If you’re investing for retirement 20 years from now, a crash today is irrelevant. If you need the money in 6 months, you shouldn’t have been in stocks in the first place.
Do I have an emergency fund? If a crash makes you panic because you might need that money for rent, the problem isn’t the market — it’s that you’re investing money you can’t afford to lose. Build 3-6 months of expenses in cash before investing aggressively.
5. If You Have Extra Cash, Consider Buying More
This is the advanced move — and only for people who have their emergency fund covered and genuinely don’t need the money for 5+ years.
Warren Buffett‘s most famous advice: “Be fearful when others are greedy, and greedy when others are fearful.” Every stock market crash in history has been a buying opportunity in hindsight.
During the April 2025 tariff crash, the S&P 500 dropped nearly 20% in seven weeks. Anyone who bought at the bottom saw a 32% gain in the following months. You won’t time the exact bottom — nobody can — but buying when everyone else is panicking has historically been rewarded.
Not sure what to buy? A broad ETF that tracks the entire market is the simplest option. One purchase, instant diversification, no stock-picking required.
What About Tariffs, Oil Prices, and [Insert Scary Thing Here]?
Every stock market crash comes with a different villain. In 2008 it was housing. In 2020 it was COVID. In 2025 it was tariffs. In 2026, it’s a cocktail of tariffs, oil prices, and geopolitical tension.
The specific cause doesn’t matter as much as you think. What matters is the pattern — and the pattern has been remarkably consistent for over 60 years:
- Something scary happens
- The market drops
- News headlines predict the apocalypse
- People panic and sell
- The market recovers
- The people who held on (or bought more) come out ahead
The S&P 500 has survived every recession, every war, every pandemic, and every political crisis since 1957. It doesn’t mean the next one will be easy — it means betting against the long-term trajectory of the American economy has always been a losing bet.
The Worst Thing You Can Do
Sell everything, move to cash, and wait for the market to “calm down.”
This sounds responsible. It’s actually the most expensive mistake in investing. Why? Because you need to be right twice: once when you sell, and once when you buy back in. Almost nobody gets both right.
What usually happens: you sell after a 15% drop, feeling smart. Then the market drops another 5% and you feel like a genius. Then it rebounds 20% in three weeks while you’re sitting in cash, waiting for the “right time” to get back in. By the time you feel comfortable reinvesting, the recovery has already happened without you.
The data backs this up. Research consistently shows that missing just the 10 best trading days over a 20-year period can cut your returns in half. And most of those best days happen right after the worst days — during the exact moments you’d be most tempted to sit on the sidelines.
The Bottom Line
A stock market crash is not a fire you need to escape. It’s a storm you need to sit through.
If your portfolio is diversified, your timeline is long, and you have an emergency fund — you’re already prepared. The best thing you can do during a stock market crash is exactly what you were doing before it: invest regularly, stay diversified, and ignore the noise.
The market has always recovered. Your patience is the only investment that guarantees returns.
