How to Decide When to Rebalance Your Investment Portfolio

Portfolio Health Requires More Than Just Routine Checkups

If you’re working with a financial advisor, you likely meet once or twice a year to review your portfolio and make adjustments based on your goals and market conditions. These scheduled check-ins are valuable—but they’re not always enough. Life doesn’t follow a calendar, and certain milestones or financial shifts may require immediate attention to keep your strategy aligned and effective.

Below, we highlight five pivotal moments when it’s especially important to revisit your portfolio with your advisor. Being proactive during these times can help you avoid costly missteps, stay on course toward your goals, and make smarter decisions with confidence.

Time-Based Rebalancing

Time-based (or calendar-based) rebalancing involves reviewing your portfolio at monthly, quarterly, or annual intervals to assess whether adjustments are needed. This method is straightforward to implement, making it a popular choice among investors and advisors. In fact, your advisor likely incorporates this review during your scheduled financial planning meetings.

While simple and consistent, this approach can sometimes lead to over-rebalancing, especially in volatile markets. Frequent adjustments may result in higher transaction costs, increased tax liabilities, and might potentially disrupt portfolio momentum. It’s important to balance discipline with flexibility to avoid unnecessary rebalancing.

Trigger Rebalancing

Trigger rebalancing is a more specific strategy that activates only when your portfolio drifts beyond a predefined threshold. Instead of rebalancing on a fixed schedule, you monitor your asset allocation and rebalance only when it deviates significantly from your target—say, a 60/40 split between stocks and bonds.

To implement this, you’ll need to define your “tolerance bands,” i.e., the acceptable range of deviation based on your risk profile. For example, you might allow a 5% drift before acting. Collaborating with your financial advisor is key to setting these parameters effectively, ensuring your portfolio stays aligned with your long-term goals without unnecessary trades.

Life Event Rebalancing

Major life changes often call for a reassessment of your financial strategy. Events such as a career shift, marriage, divorce, the birth of a child, receiving an inheritance, or approaching retirement can significantly impact your financial goals and risk tolerance.

In these moments, rebalancing your portfolio helps make it reflect your new priorities. Your advisor also will guide you through all the other financial implications, such as tax considerations, budget adjustments, benefits planning, Social Security strategies, and estate planning, to help you stay on track and make informed decisions during times of transition.

Market Events or Economic Shifts

Each year, portfolios are influenced by a mix of geopolitical tensions, market performance, and economic policy shifts. In 2025, events such as the Middle East crisis, sweeping U.S. tariffs, rising consumer delinquencies, and Federal Reserve rate cuts had a notable impact across sectors. When such disruptions occur, it’s essential to stay informed and assess whether action is warranted. Emotional reactions to market shocks are common, but depending on your long-term strategy and the nature of the event, a quick response could either help or hinder your progress.

To prepare for uncertainty, consider having your advisor stress-test your portfolio against various scenarios. You can also establish guardrails that help you stay disciplined and aligned with your goals, even when markets are volatile.

Year-End Rebalancing

The end of the calendar year is an ideal time to review your financial plan, assess progress, and make strategic adjustments, especially when it comes to taxes. Meeting with your advisor during this period can help identify opportunities to rebalance your portfolio and potentially reduce your tax liability.

One effective strategy is tax-loss harvesting, where you sell investments at a loss to offset capital gains or up to $3,000 of ordinary income. However, it’s crucial to avoid violating the IRS wash sale rule, which disallows a tax loss if you repurchase the same or a “substantially identical” security within 30 days before or after the sale.

To stay compliant and make the most of the benefit, work with your advisor to identify suitable replacement investments and ensure your trades are timed appropriately.
