Rebalancing Your Portfolio: Why, When, and How Investors Should Do It

 When you first set up your investment portfolio, you carefully chose your asset allocation—how much to put into stocks, bonds, ETFs, or other assets. But here’s the reality: markets move every day, and over time, your portfolio drifts away from its original balance. That’s where rebalancing comes in.

In this post, we’ll explore why rebalancing is essential, when you should do it, and the best strategies to make it work for you.

📌 What Is Portfolio Rebalancing?

Portfolio rebalancing means adjusting your investments back to your target asset allocation. For example:

• Suppose your ideal allocation is 60% stocks and 40% bonds.

• After a strong rally in stocks, your portfolio may shift to 70% stocks and 30% bonds.

• Rebalancing means selling some stocks (or adding more to bonds) to bring it back to 60:40.

📈 Why Is Rebalancing Important?

1. Controls Risk
   Without rebalancing, your portfolio may become riskier than you intended. A stock-heavy portfolio can expose you to big market swings.

2. Locks in Profits
   Rebalancing forces you to “sell high and buy low.” You trim winners and add to undervalued assets.

3. Keeps You Disciplined
   Instead of chasing trends or following emotions, rebalancing ensures you stick to your long-term plan.

🕰️ When Should You Rebalance?

There’s no one-size-fits-all answer, but here are common approaches:

• Time-Based Rebalancing → Once a year, half-yearly, or quarterly.

• Threshold-Based Rebalancing → When an asset class drifts beyond a set limit (e.g., 5% above or below your target).

• Hybrid Approach → Review at fixed intervals but only rebalance if the deviation is significant.

⚙️ How to Rebalance Your Portfolio

1. Review Your Current Allocation
   Compare it with your original plan.

2. Sell or Buy Assets

   • If stocks are overweight → Sell some and add to bonds.

   • If bonds are overweight → Add to equities or other growth assets.

3. Use New Investments to Rebalance
   Instead of selling, direct your fresh contributions toward the underweighted asset.

4. Consider Tax Implications
   Be mindful of capital gains tax when selling assets. Sometimes it’s better to rebalance within tax-advantaged accounts (like retirement funds).

✅ Final Thoughts

Asset allocation gives your portfolio a strong foundation, but rebalancing keeps it on track. Think of it like a health check-up—you don’t need it every day, but regular check-ins prevent long-term problems.

By staying disciplined with rebalancing, you can control risk, lock in profits, and remain aligned with your long-term financial goals.
