Expert Tips on Rebalancing Your Portfolio to Manage Risk and Improve Returns

Portfolio rebalancing is an important strategy for any investor aiming to achieve long-term success.

Whether you're new to investing or have been in the game for years, rebalancing helps you manage risk and keep emotions out of your decision-making process.

What is Portfolio Rebalancing?

In simple terms, portfolio rebalancing is the process of adjusting your investment mix back to its target allocation.

Say you’ve started with $100,000 and spread it evenly across ten different stocks, with each getting $10,000. Over time, some of these stocks will perform better than others, which means the balance of your portfolio will shift.

For example, one stock might grow to $30,000 while another drops to $8,000, leaving your portfolio skewed.

Rebalancing helps bring things back into order. It’s about selling a portion of your higher-performing stocks and potentially investing more into those that haven’t done as well, bringing your portfolio back to its intended balance.

Why is Rebalancing Important?

1. Managing Risk: Over time, certain stocks or sectors may begin to dominate your portfolio. This can increase your exposure to risk, especially if that sector takes a hit. Rebalancing ensures you’re not too dependent on any single asset, keeping your risk in check.
2. Emotional Control: Let’s be honest, investing can be emotional. When a stock is doing really well, the temptation to hold on for even greater returns can be strong, even if it means taking on more risk. Rebalancing forces you to take a disciplined approach, keeping your emotions from driving your investment decisions.

How Often Should You Rebalance?

There’s no hard and fast rule, but many investors choose to rebalance their portfolios either quarterly or annually.

Some might only rebalance after a significant market movement. The key is consistency; rebalancing regularly helps you maintain control over your portfolio without letting things get too out of balance.

The Psychology Behind Rebalancing

Investing often brings out two powerful emotions: fear and greed. Fear can push you to sell when markets dip, while greed might keep you holding onto winning stocks for too long, hoping for even more gains.

Neither of these emotions is helpful when making investment decisions.

By sticking to a rebalancing strategy, you take emotions out of the equation. You’re forced to sell some of your winning stocks and invest more in those that are lagging behind.

While this can feel counterintuitive at times, it’s a sound strategy that helps you avoid making emotional decisions that could hurt your portfolio in the long run.

Diversification and Rebalancing

Many investors believe diversification is essential, and they’re right. However, diversification for the sake of it isn’t always the best approach.

For example, holding a stock like Telstra in your portfolio just to say you’re exposed to the telecom sector might not be the best decision if that stock has been underperforming for years.

Rebalancing allows you to focus on the assets that align with your investment goals and risk tolerance, rather than sticking with a stock simply because it’s part of a particular sector.

Active vs. Passive Rebalancing

Some investors prefer to actively rebalance their portfolios, adjusting their holdings frequently based on market trends. Others take a more passive approach, only rebalancing when their allocations drift too far from their targets.

Both methods can work, depending on your investment style and how much time you’re willing to dedicate to managing your portfolio.

Income vs. Growth: Tailoring Your Rebalancing Strategy

Your investment goals will also influence how you approach rebalancing. If you’re focused on generating income, you may want to overweight stocks that offer high dividends.

On the other hand, if you’re seeking capital growth, you might prefer stocks with more growth potential, even if they come with higher risks.

For example, a retiree might prioritise high-dividend stocks for steady income, while a younger investor with a longer time horizon may lean towards riskier growth stocks with higher upside potential.

Time Horizon and Rebalancing

Your investment time frame should always factor into your rebalancing strategy. If you’ve got a long time horizon, you can afford to take on more risk, as you’ve got time to ride out any market volatility.

However, if you’re nearing retirement, your focus may shift to preserving your capital rather than seeking high returns, and your rebalancing strategy should reflect that.

Examples of Portfolio Rebalancing

Blue-Chip Stocks

Imagine you invested in Nvidia when its shares were just $10 each, and you initially bought $10,000 worth. Over time, Nvidia's price soared to $40, leaving it as a massive chunk of your portfolio. This raises the question: should you sell and lock in those gains or hold on for even more potential growth?

Rebalancing helps you avoid emotional decisions here. By selling off some Nvidia shares, you can lock in profits and reduce your exposure, but still keep a portion of your investment for further growth.

Small-Cap Speculative Stocks

In another example, let’s say you invested in a small-cap stock that skyrocketed in value. While it’s tempting to hold onto it and hope for more gains, the high risk associated with small-cap stocks means a sudden drop could wipe out those gains.

A gradual rebalancing approach, selling off small portions over time, allows you to protect your profits without drastically affecting the stock’s price.

Common Mistakes to Avoid When Rebalancing

1. Averaging Down: Some investors try to average down by buying more of a stock that’s underperforming. While this might work occasionally, it’s generally risky. You could end up throwing good money after bad. Instead, focus on why the stock is underperforming and whether it still fits your overall strategy.
2. Emotional Attachment: It’s easy to become emotionally attached to certain stocks, especially if they’ve performed well in the past. But holding onto a stock purely for sentimental reasons can cloud your judgment. Rebalancing forces you to remain objective, which is crucial for long-term success.
3. Timing the Market: Trying to time the market is difficult, even for the pros. Rather than trying to guess when the market will peak or dip, regular rebalancing helps you stay disciplined and focused on your long-term goals.

Final Thoughts

Rebalancing your portfolio isn’t just about managing risk, it’s about staying focused on your long-term investment goals. Whether you rebalance quarterly, annually, or after a major market shift, the key is to remain consistent and disciplined.

Remember, rebalancing is a process that requires careful consideration of your risk tolerance, investment horizon, and goals. Stick to your plan and don’t let emotions drive your decisions.

By making portfolio rebalancing a regular part of your investment strategy, you’ll be better positioned to navigate market ups and downs, keeping your long-term goals in sight.
