Importance of rebalancing

Importance of rebalancing. All you need to know.

Previously we discussed what is the net asset value? Now we will discuss what is rebalancing? And its importance

Over time, your portfolio might not align with your investment or savings objective because of the volatility in the market. Sometimes, some asset classes may outperform the other asset class in your portfolio and vice versa. So, accordingly, you need to rebalance your portfolio.

What is rebalancing?

Rebalancing a portfolio means changing the weightage of assets in your portfolio holdings.

It is not necessary or compulsory to change your portfolio allocation. Not taking any call for rebalancing is also the process of rebalancing. In simple words, let’s say if you are holding equity as 50% and debt as 50% in your portfolio, as per the market conditions, financial goal, and considering other factors, you may not require changing the allocation.

You may require doing a frequent review of your portfolio but may not require rebalancing. Keeping track of your portfolio and rebalancing it whenever required is essential.  

For example, suppose you want to accumulate Rs 1 Crore for your daughter’s higher education over 15 years, so you need to start with a SIP Amount of Rs 17,018/- per month.

Target Amount for Education₹ 1,00,00,000
Investment Horizon15 Years
SIP Amount₹ 17,018
Actual Wealth Accumulated₹ 1,00,00,153
Portfolio XIRR14.57%

Let’s see how your portfolio has grown over time, even in turbulent times, if you were doing portfolio rebalancing. We will see in comparison with BSE Sensex as Benchmark.

By looking at the above graphical presentation, you can see that the portfolio has been rebalanced from time to time. All the arrows represent when the rebalancing has been done. Here, we did not try to time the market.

If you look at the period from January 2019 to December 2021, the portfolio’s volatility is reducing. To understand this better, look at the March 2020 crash period.

BSE Sensex has been down by almost -29% from its recent pick in Dec ’19, whereas the portfolio is down by almost 5% only because rebalancing in the portfolio is being done continuously.

When you do goal-based investing, the idea is to achieve the goal with optimized risk instead of running out of cash. The above portfolio has been rebalanced to reduce the risk when you are close to your target; the risk comes down to low risk from the high-risk category.

In the end, the capital should be preserved because, in a pre-defined event like child education, child wedding, retirement, etc we cannot delay it, but we can preserve our capital gains by shifting them to a safer asset class.

The below table shows how the risk in the portfolio has been reduced.

Now, you may say that if you remain invested without rebalancing your portfolio, you could have achieved your target because the market has recovered after that crash. Yes, you are right, but that would be with a very high risk.

Let’s assume a situation where the market did not recover after the crash. Then, you will not be able to fund your daughter’s education.

So basically, you derailed from the entire goal. The time and money you have invested for the past 15 years come down to zero. Because that downside risk is very high, you cannot push that pre-defined event/goal.


Rebalancing the portfolio is critically essential. In a pre-defined event/goal, you cannot delay it. But with the help of rebalancing, you can achieve it even if the market is crashed. So, consider rebalancing a crucial part of your portfolio.
