How Rebalancing Helps Protect Your Investment Strategy

March 10, 2026

Rebalancing is an important part of managing investments over the long term.

If starting an investment portfolio is like buying a car, it takes research, planning, and key decisions. Rebalancing is like routine maintenance. It may take some effort at times, but the goal is to keep things running smoothly so your financial plan stays on track.

What Is Portfolio Rebalancing?

Rebalancing is the process of adjusting your investments to keep your portfolio aligned with your intended asset allocation.

When investors begin building a portfolio, they usually establish a target mix of assets based on their goals, time horizon, and tolerance for risk. For example, someone might decide that their portfolio should consist of 50% stocks and 50% bonds.

Over time, however, market performance causes those allocations to shift. If stocks experience stronger returns than bonds, the stock portion of the portfolio may grow beyond the original 50% target. This change—often called allocation drift—can alter the risk profile of the portfolio.

Rebalancing simply means restoring the original mix by trimming investments that have grown beyond their intended weight and adding to those that have fallen below their target.

Why Rebalancing Matters

Keeping your portfolio aligned with your strategy helps ensure that it continues to support your long-term goals. Each asset class plays a specific role within a diversified portfolio, and maintaining that balance can help keep your risk and return expectations on track.

Here are a few reasons rebalancing can be valuable:

Managing Risk

Higher-risk assets, such as stocks, sometimes outperform lower-risk assets like bonds. While this can boost returns, it can also cause the portfolio to become more heavily weighted toward riskier investments than originally intended.

Rebalancing restores the original balance, helping prevent the portfolio from gradually becoming more aggressive than planned.

Preserving Return Potential

At other times—such as during market downturns—lower-risk investments may outperform. When that happens, these more conservative holdings can represent a larger portion of the portfolio.

While this shift may feel comforting during volatility, portfolios that become too conservative may experience lower long-term growth potential. Rebalancing can help restore the intended balance between stability and growth.

Maintaining Diversification

As markets move, certain holdings can grow disproportionately large relative to the rest of the portfolio. Rebalancing helps redistribute assets so the portfolio remains diversified rather than concentrated in a small number of investments.

Potential Tax Considerations

Taxes can play an important role when rebalancing.

Within tax-advantaged accounts—such as 401(k)s, traditional or Roth IRAs, HSAs, or 529 plans—rebalancing typically does not create immediate tax consequences.

In contrast, rebalancing inside a taxable brokerage account may generate capital gains if investments are sold at a profit. These gains are generally taxable in the year they occur.

Selling investments at a loss may produce capital losses, which can sometimes offset gains or reduce taxable income.

Using new contributions to rebalance can sometimes help minimize taxable transactions.

How Often Should You Rebalance?

Investors typically follow one of three approaches:

Calendar method

Rebalance on a regular schedule, such as annually.

Threshold method

Rebalance whenever an asset class drifts beyond a predetermined range—often around five percentage points from its target.

Hybrid approach

Review the portfolio at regular intervals (for example, quarterly) but only rebalance if allocations have moved meaningfully off target.

While it is important to keep allocations aligned with your strategy, frequent adjustments can lead to unnecessary trading, potential tax costs, and emotional decision-making.

Getting Help With Rebalancing

Although the concept of rebalancing is straightforward, implementing it—especially in taxable accounts—can become more complicated. Some investors also feel uncomfortable executing trades themselves.

Several solutions can simplify the process, including diversified all-in-one funds such as target-date funds, automated portfolio management services, or working with a financial advisor who monitors and rebalances the portfolio on your behalf.

Over time, consistent rebalancing can help keep your investment strategy aligned with your long-term objectives while maintaining an appropriate balance between risk and opportunity.
