What should I do if the stock market crashes?

Market crashes are inevitable. Since 1950, the S&P 500 has experienced more than a dozen bear markets—declines of 20% or more—and countless smaller corrections. Yet despite this history, when the next crash comes, investors panic, sell at the worst possible time, and lock in losses that could have been avoided.

The question isn't whether the market will crash—it's what you'll do when it happens. Your response in those moments will determine whether you preserve and grow wealth or suffer lasting damage to your financial future.

Here's what business owners and professionals need to know about handling market crashes.

Why Market Crashes Happen

Markets crash for various reasons: economic recessions, geopolitical crises, financial system failures, pandemics, or simply overvaluation correcting itself. Sometimes the cause is clear in hindsight; other times, crashes feel like they came out of nowhere.

What's consistent is that crashes are driven by fear. When investors collectively lose confidence, selling accelerates, prices plummet, and panic feeds on itself. Markets overshoot on the downside just as they overshoot on the upside during bubbles.

But here's the critical truth: every market crash in history has been followed by a recovery. The S&P 500 has always—eventually—reached new highs. Investors who stayed disciplined through downturns have been rewarded. Those who panicked and sold have not.

What NOT to Do During a Market Crash

Don't Panic Sell

Selling during a crash locks in losses and guarantees you won't participate in the recovery. Historically, the best market days often come shortly after the worst days. If you're out of the market trying to avoid further losses, you'll likely miss the rebound.

Studies show that investors who sold during the 2008 financial crisis and stayed on the sidelines missed the entire recovery. Those who stayed invested—or better yet, bought more—saw their portfolios fully recover and then some.

Don't Try to Time the Bottom

It's impossible to know when the market has hit bottom. By the time it's obvious, much of the recovery has already occurred. Waiting for the "perfect" moment to get back in means you'll miss significant gains.

Don't Abandon Your Plan

If you built a financial plan based on your goals, timeline, and risk tolerance, a crash doesn't change those fundamentals. Reacting emotionally and abandoning your strategy is how long-term plans fail.

Don't Check Your Portfolio Obsessively

Constantly monitoring your portfolio during a crash amplifies anxiety and increases the temptation to make emotional decisions. The more you check, the more likely you are to panic. Step away from the screens.

Don't Ignore Your Risk Tolerance

If a market crash causes you to lose sleep, panic, or make rash decisions, your portfolio may be too aggressive for your temperament. But don't adjust your allocation in the middle of a crash—that's selling low. Make a note to adjust once markets stabilize.

What You SHOULD Do During a Market Crash

Stay Invested

The most important action is inaction. If your asset allocation was appropriate before the crash, it remains appropriate during the crash. Stay the course.

Rebalance Your Portfolio

Crashes create opportunities to rebalance back to your target allocation. If your stocks have fallen and bonds have held steady, selling some bonds to buy stocks forces you to "buy low." This disciplined approach improves long-term returns.

Keep Contributing

If you're still working and contributing to retirement accounts, keep those contributions going—or increase them if possible. You're buying shares at lower prices, which will pay off when markets recover. Dollar-cost averaging during downturns accelerates wealth building.

Consider Tax-Loss Harvesting

If you have taxable investment accounts, you can sell investments at a loss to offset gains elsewhere, reducing your tax bill. You can then immediately reinvest in similar (but not identical) assets to stay invested while capturing the tax benefit.

Avoid Looking at Your Statements

Seriously. If seeing red numbers causes you to panic, don't look. Your financial plan is measured in decades, not days or weeks. Short-term fluctuations don't matter.

Review Your Emergency Fund

Make sure you have 3–6 months of expenses in cash or cash equivalents. If your emergency fund is solid, you won't be forced to sell investments at a loss to cover unexpected expenses.

Focus on What You Can Control

You can't control the market, but you can control your savings rate, your spending, your tax efficiency, and your behavior. Focusing on these factors reduces anxiety and keeps you productive during volatility.

Opportunities During Market Crashes

Roth Conversions

Market downturns can be excellent times to convert traditional IRA funds to Roth IRAs. You'll pay taxes on the conversion at lower account values, and the future recovery happens tax-free inside the Roth.

Buying Opportunities

If you have cash on the sidelines or are receiving new income, market crashes offer the chance to buy quality investments at discounted prices. Some of the best long-term returns come from investing during periods of maximum pessimism.

Reassess Risk Tolerance

Crashes reveal your true risk tolerance. If you found yourself panicking, that's valuable information. Once markets recover, consider adjusting to a more conservative allocation that lets you sleep at night.

How Long Do Crashes Last?

It varies. The 1987 crash was sharp but recovered quickly. The 2000–2002 bear market lasted over two years. The 2008 financial crisis saw the market bottom in March 2009, with full recovery taking several years. The 2020 COVID crash was one of the fastest on record—down 34% in weeks and fully recovered within months.

The lesson? You can't predict how long a crash will last, so don't try. Focus on staying invested and maintaining perspective.

The Role of Asset Allocation

Your asset allocation—the mix of stocks, bonds, and cash in your portfolio—is your primary defense against market crashes. A portfolio with 100% stocks will experience the full brunt of a crash. A balanced portfolio with bonds and cash will cushion the blow.

The right allocation depends on your timeline and risk tolerance:

  • If you're decades from retirement, you can withstand volatility and should maintain higher stock exposure to capture long-term growth.
  • If you're near or in retirement, a more conservative allocation protects you from being forced to sell stocks at depressed prices to fund living expenses.

The key is setting your allocation when markets are calm—not adjusting it in panic during a crash.

When to Seek Professional Guidance

Market crashes test even the most disciplined investors. If you're feeling uncertain, anxious, or tempted to make major changes to your portfolio, talking to a financial advisor can help.

A good advisor provides:

  • Perspective and reassurance based on historical data
  • Behavioral coaching to prevent costly emotional decisions
  • Strategic guidance on rebalancing, tax-loss harvesting, and Roth conversions
  • A plan that keeps you focused on long-term goals, not short-term noise

Working with an advisor doesn't eliminate market volatility, but it can prevent you from making the mistakes that turn temporary losses into permanent ones.

Your Next Step

Market crashes are stressful, but they're also a normal part of investing. The investors who build lasting wealth are those who stay disciplined, stick to their plan, and resist the urge to react emotionally.
