How to Protect Your Investments During a Market Crash

A market crash cannot be made risk-free. Use a plan built around your goals, diversify, protect money needed soon, and avoid rushed or fraudulent decisions.

You cannot make a portfolio crash-proof or know when a market decline will happen. You can prepare to manage risk, keep near-term needs separate from long-term investments, and avoid being forced into rushed decisions. The steps below reflect general U.S. regulator guidance, not a personal allocation recommendation.

Start with your plan, not a prediction

When markets fall, first check whether your investment plan still fits your goals, financial circumstances, risk tolerance, and the time horizon for each goal. The SEC says asset allocation depends on factors such as risk tolerance and investing timeframe; there is no single allocation that suits everyone. See the SEC’s Beginners’ Guide to Asset Allocation, Diversification, and Rebalancing and its Investor.gov Tips for 2026.

  • Ask when you expect to use the money and whether a decline could interfere with that goal.
  • Consider whether your finances and ability to tolerate losses have changed since you set the plan.
  • Avoid making an all-or-nothing buy-or-sell decision solely to react to market headlines. The cited guidance does not predict crashes or prescribe a universal response.

Use diversification to spread risk, not eliminate it

Diversification means spreading investments across asset categories and within each category, rather than relying heavily on one holding or narrow part of the market. It can reduce overall risk, but it cannot ensure gains or prevent losses. The SEC’s Investor.gov puts the limit plainly: “Diversification can’t guarantee that your investments won’t suffer if the market drops.” Read Diversify Your Investments for the SEC’s overview.

Review whether your holdings are diversified in a way that supports your plan; do not assume every asset category will rise when stocks fall. Diversification is a way to manage exposure, not a reliable short-term forecast or a guarantee against a market decline.

Separate money for near-term needs from long-term investments

If you expect to withdraw money soon, that portion deserves special attention. A downturn can occur at the same time you need cash, potentially forcing you to sell investments at an unfavorable moment. A 2020 bulletin from the SEC, CFTC, FINRA, NFA, and NASAA says investors expecting near-term withdrawals may consider more conservative, liquid investments for that money. The bulletin does not name one suitable investment for everyone: Tips for World Investor Week 2020.

Keep the decision tied to when the money is needed and your circumstances. The cited guidance does not establish a universally appropriate security or allocation.

Keep an emergency reserve if you can

Accessible savings for unexpected expenses can reduce pressure to sell investments when markets are down. A 2022 bulletin from the SEC, CFTC, FINRA, NFA, and NASAA gives three to six months of living expenses as an example emergency-savings goal—not a requirement for every household. Your needs and ability to save may differ. See Investor Resilience – World Investor Week 2022.

Rebalance when your holdings drift from your plan

Rebalancing brings a portfolio back toward its chosen allocation after market movements change the proportions of its holdings. It is a way to maintain a plan, not a method for predicting the market’s next move. The SEC describes two possible review approaches:

  • Calendar-based: review the allocation on a schedule.
  • Threshold-based: review when an allocation moves a specified amount away from its target.

The SEC says rebalancing generally works best relatively infrequently. Before acting, account for possible transaction fees and tax consequences, which can depend on your account and circumstances. The SEC’s asset allocation guide discusses rebalancing and these considerations.

Watch for scams that exploit market anxiety

Fear and urgency can make extraordinary promises sound appealing. Be wary of claims of high guaranteed returns with little or no risk, and independently check information before acting. The SEC’s 2026 bulletin advises investors to verify information and guard against impersonation; the 2022 multi-agency bulletin also urges research and vigilance against investment fraud. See Investor.gov Tips for 2026 and Investor Resilience – World Investor Week 2022.

If you need help applying general guidance to your goals, account, taxes, or financial circumstances, consider consulting a qualified financial professional.
