With stock markets maintaining elevated valuations and bond prices declining significantly, financial professionals are highlighting portfolio rebalancing as a strategic approach for investors navigating current market conditions.
Recent market performance has created an imbalance in many investment portfolios. The S&P 500 has delivered substantial gains over the past several years, rising 24% in 2023, 23% in 2024, and 16% in 2025, considerably exceeding the long-term average of approximately 10%. In 2026, stocks have continued their upward trajectory, gaining more than 11% despite slight pullbacks from August peaks. Conversely, bond markets have experienced sustained weakness following the Iran war beginning at the end of February. Government bond yields have climbed to multiyear highs as investor concerns about inflation and debt mount, causing long-term bond funds to decline in value. The iShares 7-10 Year Treasury Bond ETF has fallen more than 4% in 2026, while the Fidelity Long-Term Treasury Bond Index Fund has dropped more than 5%.
This divergent performance has shifted most portfolios toward equities, potentially making them riskier than investors intended. Rebalancing—the process of adjusting asset allocation back to target levels—can help address this misalignment. The strategy allows investors to lock in stock gains by shifting proceeds to bonds, effectively implementing a disciplined “buy low, sell high” approach. Financial advisors note that rebalancing also removes emotional decision-making from investing, reducing the temptation to time markets or abandon stocks entirely amid current geopolitical tensions and economic uncertainties.
Financial professionals caution that rebalancing need not occur all at once and stress it does not mean abandoning equities entirely. Investors can use gradual adjustments, direct new contributions toward underweighted asset classes, or employ tax-aware strategies to manage allocations. Those with taxable brokerage accounts should be mindful of potential capital gains taxes, while retirement account holders typically face fewer tax complications. Most major asset managers and retirement plan administrators provide risk tolerance questionnaires to help investors determine appropriate portfolio compositions aligned with their comfort with potential losses.
