Building a successful investment portfolio is about more than simply choosing quality investments. As markets fluctuate, your portfolio naturally changes over time, potentially exposing you to more risk than you originally intended. That's why portfolio rebalancing is one of the most important, and often overlooked aspects of long-term investing.
Whether you're saving for retirement, funding your children's education, or building generational wealth, maintaining the right investment mix helps keep your financial plan aligned with your goals.
At Dunbrook Associates, we believe successful investing requires ongoing monitoring and adjustments—not emotional reactions to market headlines. Rebalancing your portfolio is a disciplined approach that helps manage risk while supporting long-term financial growth.
Portfolio rebalancing is the process of adjusting your investments to restore your desired asset allocation.
Asset allocation refers to how your investments are divided among different asset classes, such as:
For example, suppose your investment strategy is:
After several years of strong stock market performance, your portfolio may shift to:
While this growth may seem positive, your portfolio now carries significantly more risk than originally intended. Rebalancing involves selling a portion of the investments that have grown beyond their target allocation and purchasing investments that have become underweighted.
The goal isn't to maximize returns in any given year it's to maintain a level of risk that matches your financial objectives.
Every investment grows at a different pace.
During strong equity markets, stocks often outperform bonds, causing equity allocations to increase. During periods of economic uncertainty, bonds or defensive investments may outperform equities.
Without periodic adjustments, your carefully designed investment strategy gradually changes.
This phenomenon is known as portfolio drift, and over time it can significantly alter both the expected return and risk level of your investments.
Many investors focus exclusively on returns while overlooking risk management.
Rebalancing helps accomplish several important objectives.
Your portfolio was likely built based on your financial goals, investment timeline, and comfort with market fluctuations.
Allowing investments to drift too far from their target allocation may expose you to greater volatility than you're comfortable accepting.
Maintaining your intended allocation helps ensure your investments continue reflecting your personal risk profile.
One of the greatest benefits of rebalancing is that it removes emotion from investment decisions.
Instead of chasing the latest market trends or reacting to news headlines, rebalancing follows a consistent, rules-based approach.
It naturally encourages investors to:
This disciplined process can help improve long-term investment outcomes.
Diversification remains one of the most effective ways to manage investment risk.
Over time, certain sectors, industries, or geographic markets may outperform others.
Without rebalancing, your portfolio may become overly concentrated in a single area.
Maintaining diversification helps reduce dependence on the performance of any one investment or asset class.
There isn't a single "perfect" time to rebalance. Instead, financial professionals generally use one or a combination of several approaches.
Many investors rebalance on a predetermined schedule.
Common intervals include:
Annual and mid year reviews often provide a good balance between maintaining discipline and avoiding unnecessary trading.
Regular reviews also allow investors to revisit financial goals, retirement plans, tax strategies, and changing personal circumstances.
Some advisors recommend rebalancing whenever an asset class moves beyond a predetermined threshold.
For example:
Target Allocation:
Rebalance if:
This "tolerance band" approach allows portfolios to fluctuate naturally while preventing excessive drift.
Your financial goals may change significantly over time.
Major life events often warrant a portfolio review, including:
These milestones may require adjustments to your investment strategy beyond simple rebalancing.
Risk tolerance often changes as retirement draws closer.
Someone with 30 years before retirement may be comfortable with a higher allocation to equities.
However, someone planning to retire within five years may benefit from gradually reducing portfolio volatility.
Regular rebalancing ensures your investments continue matching your changing time horizon.
Large market swings often create substantial shifts in asset allocation.
For example:
Following a strong bull market:
Following a market correction:
While market downturns can be uncomfortable, disciplined rebalancing often encourages investors to purchase investments when prices are lower rather than waiting until markets recover.
A common misconception is that rebalancing always improves investment returns.
In reality, the primary purpose of rebalancing is risk management, not return maximization.
During prolonged bull markets, portfolios that aren't rebalanced may actually generate higher returns because they maintain larger equity positions.
However, those same portfolios often experience larger declines during market downturns.
Rebalancing seeks to create a smoother investment experience that aligns with your long-term objectives rather than chasing maximum short-term gains.
Selling investments to rebalance may trigger capital gains taxes in non-registered investment accounts.
For this reason, financial professionals often consider tax implications before making adjustments.
Possible strategies include:
A comprehensive financial plan evaluates both investment strategy and tax efficiency together.
Many investors hesitate to rebalance during declining markets because selling stable investments to purchase falling assets feels counterintuitive.
However, history has shown that market declines eventually recover, although the timing is never guaranteed.
Rebalancing during market corrections may allow investors to purchase quality investments at lower prices while maintaining their long-term investment strategy.
Rather than attempting to predict market bottoms or tops, disciplined investors focus on maintaining an appropriate asset allocation.
Some investors go years without reviewing their portfolios.
During that time, allocations can drift substantially, increasing unintended risk.
Investing more heavily in last year's best-performing asset class often results in buying high.
Successful investing typically requires looking beyond recent performance.
Concentrating investments in one company, industry, or market increases portfolio risk.
Diversification remains one of the most effective long-term investment strategies.
Fear and greed often lead investors to buy high and sell low.
Rebalancing introduces discipline and consistency, helping remove emotion from investment management.
Investment portfolios should be reviewed regularly not just during periods of market volatility.
Annual or semi-annual meetings with your financial advisor provide opportunities to review:
A comprehensive financial review ensures your investment strategy continues supporting your broader financial plan.
Financial markets experience periods of growth, decline, uncertainty, and recovery.
Attempting to predict every market movement is extremely difficult, even for experienced professionals.
Instead of focusing on short-term fluctuations, successful investors typically benefit from:
These habits often contribute more to long-term success than attempting to time the market.

For most investors, however, long-term investing offers a more practical path toward meaningful financial goals. Rather than trying to predict the market’s next move, a long-term strategy focuses on building a diversified portfolio, remaining invested through changing conditions, and allowing time and compounding to do much of the work.
When building an investment portfolio, one of the most important decisions is whether to focus primarily on growth, income, or a combination of the two. Both growth investing and income investing can play a valuable role in a long-term financial plan, but they are designed to meet different needs.
Whether you're just beginning your financial journey or approaching retirement, developing strong financial habits today can significantly improve your financial future. The good news is that these habits don't require perfection they simply require consistency.
