Rebalancing Investment Portfolios: Yearly Refresh For Optimal Returns

Should you rebalance your investment portfolio each year? Well, it depends.

Rebalancing is the process of buying and selling assets to return your portfolio to its original composition. It is a way to manage risk and ensure your investments remain in line with your financial goals and risk tolerance. While rebalancing is important, doing it too often may cause you to miss out on positive momentum in your stock investments and incur unnecessary taxes. On the other hand, not rebalancing often enough may cause your portfolio to drift too far from your original asset allocation, increasing risk and reducing growth potential.

There are two main approaches to rebalancing: calendar-based and trigger-based. With calendar-based rebalancing, you adjust your portfolio on a regular schedule, such as quarterly or annually. This method is simple to implement but may result in unnecessary taxable capital gains if there have only been small changes in your portfolio since the last rebalance. Trigger-based rebalancing, on the other hand, involves rebalancing when your portfolio drifts beyond certain predetermined limits, such as if an asset class changes by 10% or more relative to its target allocation. This method ensures that rebalancing occurs promptly when needed but may be more difficult to implement and could result in more frequent rebalancing during periods of high market volatility.

So, how often should you rebalance? Generally, it is recommended to rebalance at least once a year. However, the optimal frequency depends on various factors, including your age, transaction costs, personal preferences, and tax considerations. For example, younger investors may not need to rebalance as frequently as those nearing retirement. Additionally, it is important to consider the tax implications of rebalancing, as selling profitable investments may incur capital gains taxes.

Rebalancing reduces portfolio volatility and risk

Rebalancing is an important way to help minimise volatility in a portfolio and may improve long-term returns. It is a process of buying and selling assets to reach an investor's desired portfolio composition. This is especially important during times of significant market volatility.

How Rebalancing Reduces Volatility and Risk

Over time, the market value of each security within a portfolio will earn a different return, resulting in a weighting change. This will change the risk profile of the portfolio. Rebalancing allows an investor to realign their portfolio with their risk tolerance and overall investing strategy.

For example, an investor may start with a mix of 60% stocks and 40% bonds, which has historically provided attractive risk-adjusted returns. If the market value of their stocks grows and their bonds do not, they may end up with 70% of their portfolio value in stocks and only 30% in bonds. To rebalance, they would sell some stocks and buy more bonds to return to their original 60/40 allocation.

There are two main approaches to how often an investor should rebalance their portfolio: a calendar-based approach and a trigger-based approach. The calendar-based approach adjusts a portfolio on a regular timetable, such as quarterly or annually. The trigger-based approach involves rebalancing when a portfolio drifts beyond certain predetermined limits, such as if an asset class changes by 10% or more relative to its target allocation.

While rebalancing is important, it should not be done too frequently as this may cause an investor to miss out on potential momentum gains. On the other hand, not rebalancing enough may cause a portfolio to no longer be on track to meet an investor's financial goals. Therefore, it is recommended that a portfolio is rebalanced at least once a year.

It's important to do annually, but not too often

It is important to rebalance your investment portfolio at least annually, but not too often.

Rebalancing your portfolio is the process of changing the weightings of assets to maintain your target asset allocation and keep your risk levels in check. It is a way of minimising volatility and ensuring your portfolio remains in line with your investment strategy and risk profile.

The optimal frequency for rebalancing depends on a variety of factors, such as age, risk tolerance, and transaction costs. While some professionals recommend rebalancing your portfolio every quarter, once a year is generally considered sufficient. Less frequent rebalancing may even be beneficial, as it allows your winning assets to grow for longer and can lead to greater overall returns. However, if you don't rebalance often enough, your portfolio may no longer meet your investment objectives. It may carry more risk than you are comfortable with, or it may not have enough growth potential to achieve your investment goals.

There are two main approaches to rebalancing: calendar-based and trigger-based. Calendar-based rebalancing adjusts your portfolio on a regular timetable, such as quarterly or annually. Trigger-based rebalancing, on the other hand, occurs when your portfolio drifts beyond certain predetermined limits, such as when an asset class changes by a certain percentage relative to its target allocation. While calendar-based rebalancing is simple to implement, it may be out of sync with the actual changes in your portfolio's asset allocation. Trigger-based rebalancing, on the other hand, ensures that rebalancing occurs promptly when the portfolio drifts too far from its predetermined goals but doesn't rebalance excessively.

When deciding how often to rebalance, it's important to consider the potential tax implications. Rebalancing too frequently can result in unnecessary taxes in a taxable account. Additionally, it's important to remember that rebalancing is not about completely overhauling your portfolio but rather making restorative changes to keep it in line with your original investment strategy and risk tolerance.

Use a robo-advisor to automate the process

Robo-advisors are digital platforms that provide automated, algorithm-driven financial planning and investment services with little to no human supervision. They are a good option for those who want to automate the process of rebalancing their investment portfolio.

Robo-advisors use modern portfolio theory (or some variant) to build passive, indexed portfolios for their users. Once portfolios are established, robo-advisors continue to monitor them to ensure that the optimal asset-class weightings are maintained, even after market moves. They achieve this by using rebalancing bands, which means that every asset class or individual security is given a target weight and a corresponding tolerance range. When the weight of a holding moves outside of the allowable band, the entire portfolio is rebalanced to reflect the initial target composition.

Robo-advisors are often inexpensive and require low opening balances, making them accessible to retail investors. They are best suited for traditional investing and are not the best option for more complex issues, such as estate planning.

Some of the best robo-advisors in the market include Wealthfront, Betterment, Vanguard Digital Advisor, SoFi Automated Investing, and Fidelity Go.

There are different rebalancing strategies

There are several rebalancing strategies that investors can use to maintain their desired level of risk and ensure their portfolio remains aligned with their financial goals. Here are some of the most common strategies:

• Calendar-based rebalancing: This approach adjusts your portfolio on a regular timetable, such as quarterly or annually. The advantage of this method is its simplicity, but it may not always be in sync with the actual changes in your portfolio's asset allocation. For instance, a significant drift could occur between rebalancing intervals, or rebalancing could happen even if there are only minor changes in your portfolio, potentially triggering unwanted taxable capital gains.
• Trigger-based rebalancing: This strategy involves rebalancing when your portfolio drifts beyond certain predetermined limits. For example, if an asset class changes by 10% or more relative to its target allocation. Trigger-based rebalancing promptly corrects deviations from the predetermined asset allocation goal and avoids excessive or unnecessary rebalancing. However, it may be more complex to implement, and during periods of high market volatility, it could result in more frequent rebalancing and potential taxable capital gains.
• Percentage-of-portfolio rebalancing: This approach focuses on the allowable percentage composition of each asset or security in your portfolio. Each asset class or security is assigned a target weight and a corresponding tolerance range. When the weight of any holding goes outside the allowable range, the entire portfolio is rebalanced to reflect the initial target composition. This strategy is slightly more intensive but helps maintain the desired asset ratios based on the investor's risk tolerance.
• Constant-proportion portfolio insurance (CPPI): This strategy assumes that as an investor's wealth increases, their risk tolerance also increases. CPPI involves maintaining a minimum safety reserve in cash or risk-free government bonds and investing the remainder in risky assets. The amount of money invested in stocks is determined using a formula that considers the total portfolio assets and the allowable floor (minimum safety reserve). CPPI must be used alongside other rebalancing and portfolio optimisation strategies as it does not specify the rebalancing frequency.

It's about managing risk, not chasing returns

Rebalancing is the process of buying and selling assets to maintain your desired level of investment risk. It is a way to ensure your portfolio remains aligned with your financial goals, risk tolerance, and investment strategy.

Over time, the value of your investments will change, causing your original asset allocation to shift. This shift can increase or decrease the risk of your portfolio. For example, if you initially invested 50% in a bond fund, 10% in a Treasury fund, and 40% in an equity fund, the equity portion may dramatically outperform the bond and Treasury portions by the end of the year. As a result, your portfolio will now have a higher percentage allocated to the equity fund, increasing the overall risk.

The frequency of rebalancing depends on various factors, such as age, risk tolerance, and transaction costs. While some professionals recommend quarterly rebalancing, others suggest that doing so once a year is sufficient.

There are two main approaches to determining the timing of rebalancing:

• Calendar-based rebalancing: This approach adjusts your portfolio on a regular timetable, such as quarterly or annually. It is simple to implement but may sometimes be out of sync with actual changes in your portfolio's asset allocation.
• Trigger-based rebalancing: This method involves rebalancing when your portfolio drifts beyond certain predetermined limits. For example, if an asset class changes by 10% or more relative to its target allocation. Trigger-based rebalancing promptly realigns your portfolio with your risk tolerance but may be more challenging to implement and could result in more frequent rebalancing during periods of high market volatility.

Strategies for Rebalancing Your Portfolio

• The "While You're at It" Strategy: Each time you invest new money or withdraw funds, identify underrepresented or over-weighted asset types in your portfolio. You can then adjust your position accordingly with each contribution or withdrawal.
• The "Home Base" Strategy: If most of your retirement assets are in a single account, such as a 401(k) or IRA, focus your rebalancing efforts on that main account. This is convenient because what happens in that account has the most significant impact on your overall savings. Additionally, selling within these tax-advantaged retirement accounts won't trigger short- or long-term capital gains taxes.
• The "I Treat All My Children the Same" Strategy: If you have multiple investment accounts with similar amounts, treat each as a separate, fully balanced portfolio. Decide on your target asset allocation mix and deploy the same strategy in each account, taking into account the investment selection and tax status of each account.
• The "Sweat the Biggest Stuff" Strategy: U.S. large-cap stocks often constitute the biggest slice of investors' portfolios. Any shift in this area can create a significant impact on your original allocation. Therefore, if you notice any major shift from your original allocation plan, start by checking your large-cap stock positions to see if adjustments are needed.

Tips for Effective Rebalancing

• Avoid checking investment values too frequently: Checking daily or weekly can create a sense of urgency to act, leading to overtrading and inferior investment returns.
• Create a personal investment policy statement: Develop a statement that includes your investment mix, asset allocation, and rebalancing parameters. Stick to this predetermined plan to maintain consistency.
• Minimize taxes in taxable accounts: In taxable brokerage accounts, explore options to minimize selling high-performing investments. Consider selling losing positions to offset capital gains or using tax-loss harvesting strategies.
• Maintain a long-term focus: It's easy to get distracted by short-term market fluctuations, but acting on these changes can derail your long-term goals. Remember that investing is a long-term strategy for future financial security.
• Consider using a robo-advisor: If you feel overwhelmed, consider using a robo-advisor. These automated services can help with portfolio selection and rebalancing, taking the burden off your shoulders.

In conclusion, rebalancing your investment portfolio is a crucial aspect of managing risk and ensuring your investments remain aligned with your goals and risk tolerance. It's not about chasing returns but rather maintaining a balanced portfolio that can weather various market conditions. By implementing effective rebalancing strategies and staying focused on your long-term objectives, you can make more informed decisions and improve your overall investment experience.
