What is Portfolio Rebalancing and Why Should You Care?

Warren Buffett said that his favourite holding period for an investment is “forever.” But is this approach suitable for every asset you invest in?

Global events like COVID-19, US tariffs, rising geopolitical tensions, etc., have highlighted the importance of portfolio rebalancing. In these unexpected events, your existing investment strategy may not work efficiently, and your money will be at greater risk. 

By rebalancing your portfolio as per the scenario, you can lower risk and stay focused on your long-term financial goals even if the market keeps changing.

Key Takeaways

• Portfolio rebalancing refers to adjusting your asset allocation by buying or selling investments based on changing market conditions.
• It helps manage risk and ensure that your portfolio does not become too aggressive or conservative.
• With regular rebalancing, you can make disciplined investments and improve the long-term performance of your portfolio.

Definition of Portfolio Rebalancing

Portfolio rebalancing means buying and selling investments from time to time to keep your portfolio on track. As market movements cause your investment mix to shift, rebalancing helps mitigate risk. 

Rebalancing investments helps keep your investments in line with your goals as per your risk tolerance. It can also help improve returns by encouraging you to sell high-performing assets and buy undervalued ones.

A Detailed Example of Portfolio Rebalancing

For example, your initial strategy was to invest 30% in gold, 30% in mutual funds, 30% in bonds, and 10% in equity. 

After 1.5 years, market movements shift your allocation to 35% gold, 32% mutual funds, 28% bonds, and just 5% equity. 

To rebalance, you have to sell some gold and mutual funds and use the amount to buy more bonds and equity. Thus, you can restore your portfolio to its original target mix. 

This disciplined approach helps manage risk and keeps your investment strategy aligned with your goals despite market fluctuations.

How to Rebalance Your Portfolio?

Here is a step-by-step process to understand how to do a portfolio rebalancing:

1. Start by setting your ideal asset allocation based on your goals, risk tolerance, and investment timeline. 
2. Next, review your current investments and calculate the percentage each asset holds in your total portfolio.
3. If the current allocation differs from your target, sell assets that are too high and buy those that are too low to restore balance. During the changes, you should be mindful of taxes, especially capital gains. 
4. Finally, review your portfolio every 6 to 12 months and rebalance as needed to stay aligned with your original strategy. 

This keeps your risk in check and helps ensure your investments continue working toward your financial goals.

Why Portfolio Rebalancing is Important for You?

Some investors might wonder, “Why bother rebalancing my portfolio?”. Here is the answer:

• Maintains Your Original Asset Allocation: Portfolio rebalancing ensures your portfolio stays on track with your risk profile and investment goals. This prevents unwanted negative returns due to market fluctuations.
• Enhances Risk Management: It reduces the risk of overexposure to certain asset classes and keeps your investments diversified and balanced.
• Facilitates Strategy Updates: As your goals and risk tolerance change over time, rebalance your portfolio to match your new strategy and goals.
• Promotes Disciplined Investing: By selling high-performing assets and buying undervalued ones, portfolio rebalancing follows the principle of buying low and selling high.

Limitations of Portfolio Rebalancing

Though rebalancing investments has benefits, it also comes with several limitations, such as:

1. Frequent rebalancing can lead to increased transaction costs and reduce your overall returns. 
2. It also requires a certain level of expertise, and mistakes in timing or asset selection may expose the portfolio to greater risks or missed opportunities. 
3. Additionally, selling high-performing assets to rebalance might result in lost gains if those assets continue to rise, and may also trigger capital gains taxes.
4. Rebalancing often involves selling winning assets and buying underperforming ones, a strategy that may feel counterintuitive and emotionally difficult for many investors.

Common Mistakes You Must Avoid While Rebalancing

If you are considering rebalancing your portfolio, you must be careful about the common mistakes:

• Sometimes, investors focus only on profits and losses, overlooking their risk profile, which can lead to impulsive and poorly informed decisions.
• Your personal biases or market predictions should not influence the rebalancing process. Instead, you need to follow a disciplined, rule-based approach to avoid costly errors.
• If you do not consider the impact of taxes and transaction costs, it can minimise your returns. Remember about capital gains taxes and transaction fees before you make any changes.
• In case you try to rebalance on your own without expert advice, it may lead to wrong decisions, especially if your portfolio is complex or you are a beginner.

Final Words

Market-linked returns are always unpredictable. Therefore, as an investor, you should understand and apply the portfolio rebalancing techniques.
