A prolonged market decline is a reason to review your investment plan—not, by itself, a reason to abandon it. Start with your goal and time horizon, check how your portfolio compares with its intended allocation, and account for cash needs, taxes, and costs before deciding whether anything should change. There is no single allocation that fits every investor.

1. Revisit the goal and when you will need the money

Write down what the money is for and when you expect to use it. Then check whether your goal, time horizon, income, obligations, risk tolerance, or broader financial situation has changed. Those factors—not the market decline alone—help determine whether your intended allocation still fits. An allocation for a distant retirement goal may be unsuitable for money needed soon. The SEC notes that “There is no single asset allocation model that is right for every financial goal.” SEC guide to asset allocation, diversification, and rebalancing.

2. Map your portfolio, including concentration

Review accounts where practical and estimate the current share held in stocks, bonds, cash, and other investments. Compare the combined picture with your intended allocation rather than judging each account in isolation.

Look through mutual funds and ETFs to understand what they own. A fund is not automatically diversified: a narrowly focused fund can leave you concentrated in one industry, company type, or other segment. Check both the balance between asset classes and the concentration within each one. Diversification can help manage risk, but it cannot guarantee against investment losses. SEC guide.

3. Check near-term cash needs and debt

Before considering investment changes, account for upcoming expenses, emergency savings, and high-interest debt. The SEC-led World Investor Week bulletin dated October 5, 2026, says adequate savings can reduce the risk of having to sell investments prematurely. It gives three to six months of living expenses as an example savings goal—not a universal requirement. The bulletin also notes that some credit-card balances may carry rates of 18 percent or more; that is a general example, not a rate for every card or borrower.

4. Separate allocation drift from a change in your plan

Compare your current mix with the target you set for the goal. Market movements can cause portfolio weights to drift. Rebalancing means bringing the mix back toward that target; it is different from changing the target because recent winners look attractive or recent losers feel uncomfortable.

If your goal and circumstances are still consistent with the target, rebalancing may restore the plan. If your horizon, risk tolerance, finances, or goal has materially changed, consider whether the target itself needs review. The decision is personal; the SEC’s rebalancing guide describes the mechanics but does not prescribe a universal mix.

5. Compare practical ways to rebalance before trading

There is more than one way to address a gap between current weights and a target. Which approach is suitable depends on your circumstances; regulators do not rank these options universally.

Approach How it works What to check
Direct new contributions Send new investment money toward categories that are underweight. Whether contributions are available, whether the underweight is meaningful, and how the resulting mix compares with the target.
Sell and buy Sell some overweight holdings and use the proceeds to buy underweight categories. Potential taxes, transaction charges, liquidity needs, and whether trades fit the plan.
Combine both Use contributions where practical and trade only if needed to move closer to the target. The same tax, cost, liquidity, and target-fit considerations as above.

Before acting, review your account statements, fund prospectuses, disclosures, and trade confirmations. Consider tax consequences for your jurisdiction and account type, transaction charges, fund expense ratios, advisory fees, and other account costs. The SEC’s 2025 fee bulletin illustrates why recurring costs matter: in its hypothetical example, $100,000 growing at 4% annually for 20 years becomes approximately $208,000 with a 0.25% annual fee, $198,000 with a 0.50% fee, or $179,000 with a 1.00% fee. These are illustrative calculations, not observed outcomes or forecasts for a particular investment. SEC explanation of how fees and expenses affect a portfolio.

6. Avoid turning a review into a market prediction

A review should answer whether your plan still fits, not attempt to forecast when prices will recover. The SEC-led October 5, 2026 bulletin cautions that short-term trading or trying to time the market can lead investors to buy after highs and sell while markets are falling. It says patient, periodic investing can mitigate short-term swings; that does not guarantee a gain or a recovery on any schedule. World Investor Week 2026 investor bulletin.

7. Get qualified help when the decision is individual

Consider a qualified financial professional or tax adviser if your situation involves a major change in goals, complex holdings, uncertainty about taxes, or difficulty assessing whether your target still fits. Check credentials and disciplinary history rather than relying on a title or sales pitch. U.S. investors can use FINRA BrokerCheck and the SEC’s Investment Adviser Public Disclosure (IAPD); investors elsewhere should verify the relevant local regulator and registration process. Tax rules and account options vary by jurisdiction and can change, so confirm current official guidance before implementing a decision.
