Portfolio Rebalancing – a new perspective

Often we speak of the need to Rebalance the portfolio. This is to ensure that one remains in line with their risk appetite and balances between the risk and rewards. While it is important part of financial discipline ensuring there are no major shocks to your portfolio, one needs to be also aware of playing it optimally for ones advantage. Let us explore some interesting perspectives:

 

 

Alternate strategy that one could explore include:

 

  • Instead of immediately selling existing investments (which might incur capital gains taxes and transaction costs), tweaking your future investment strategy to bring the portfolio back into balance can be a smarter and more tax-efficient approach. Here’s why this makes sense and how it can be executed effectively:

 

 

Advantages of Tweaking Future Investments

 

  1. Tax Efficiency
    • Selling assets for rebalancing can trigger capital gains taxes, especially if you’ve held them for a short time. By channelling your new investments into asset classes that are underweight in your portfolio, you can correct the imbalances progressively while you can also avoid or delay the taxes implications on selling assets in a bid to balance immediately.
  2. Reduced Transaction Costs
    • Selling and buying assets frequently can result in brokerage fees or penalties. Tweaking future contributions minimizes unnecessary trading and the associated costs.
  3. Alignment with Cash Flow
    • New income or windfalls can be directed strategically toward underrepresented asset classes in the portfolio without disrupting existing investments.
  4. Avoiding Behavioural Pitfalls
    • Selling investments, especially winners, can be emotionally challenging. Tweaking future investments allows you to rebalance without making hasty decisions.

 

How to Implement Tweaked Rebalancing

 

  1. Assess Current Allocation
    • Identify which asset classes (e.g., equity, debt, real estate) or sectors are overweight or underweight relative to your target allocation.
  2. Channel New Contributions
    • Direct fresh investments or savings towards the underweighted parts of your portfolio. For instance:
      • If equities are underweight, contribute to an equity mutual fund or stock portfolio.
      • If debt instruments are underweight, invest in fixed-income securities or bonds.
  3. Monitor Regularly
    • Check your portfolio quarterly or annually to assess progress. Avoid reacting to short-term market fluctuations.

 

When Selling May Still Be Necessary

 

While tweaking future investments is ideal, there are scenarios where selling may be warranted:

  1. Excessive Risk
    • If an asset class or stock becomes disproportionately large (e.g., a single stock grows to 50% of your portfolio), it might expose you to undue risk.
  2. Underperformance or Changes in Fundamentals
    • If an asset no longer aligns with your investment goals or its fundamentals have deteriorated, it may be prudent to sell.
  3. Rebalancing Within Tax-Advantaged Accounts
    • If you have investments in tax-advantaged accounts (e.g., NPS funds or ULIPs or other retirement accounts in India), rebalancing within these accounts can avoid immediate tax consequences.

 

Also one needs to be aware that exiting from a equity heavy portfolio in a bid to balance in a bullish phase of the market may lead to the lost opportunity on optimising on the rising portfolio. Having said that, it is very important to have a deeper understanding of your stock/portfolio, its performance, the business, the sector, the company’s future growth prospectus and the general economic conditions influencing the business of the company, the economic phase and many other such variables that influence the portfolio besides time to your goals. There are no right answers, every situation is unique and one may use strategies like scaling out to book profits in the tax advantageous manner.

 

Let us try to understand with an example how tweaking future investments can be used as a strategy rather than exiting from current holdings in a bid to achieve immediate balance in portfolio.

 

Example: Tweaking Future Investments to Rebalance

 

Scenario:

Your target asset allocation is 60% equity and 40% debt, but due to a strong stock market rally, your portfolio shifts to 75% equity and 25% debt.

Current Portfolio Value:

  • Total Portfolio: ₹10,00,000
    • Equity: ₹7,50,000 (75%)
    • Debt: ₹2,50,000 (25%)

Desired Portfolio Allocation:

  • Equity: ₹6,00,000 (60%)
  • Debt: ₹4,00,000 (40%)

Gap to Correct:

  • Overweight in equity: ₹1,50,000
  • Underweight in debt: ₹1,50,000

 

Action Plan: Tweaking Future Investments

  1. New Contributions:
    • Suppose you have an additional ₹1,00,000 to invest in the next year. Instead of putting it into equity (which is overweight), you direct the entire ₹1,00,000 toward debt instruments like PPF, debt funds, or bonds.
  2. Systematic Investment Plan (SIP):
    • Start a monthly SIP of ₹10,000 in a debt fund for 12 months, ensuring consistent rebalancing over time.

 

Outcome After One Year:

  • New Contributions to Debt: ₹1,00,000 (additional savings + reinvested income).
  • Adjusted Portfolio:
    • Equity: ₹7,50,000 (remains unchanged).
    • Debt: ₹3,50,000 (₹2,50,000 existing + ₹1,00,000 new contributions).
    • Total: ₹11,00,000.
  • New Allocation:
    • Equity: ~68% (₹7,50,000/₹11,00,000).
    • Debt: ~32% (₹3,50,000/₹11,00,000).

 

This strategy avoids disruption and tax costs while methodically correcting imbalances.

 

For ease of understanding the continuing yield /returns in the portfolio is ignored in the above working.

 

Now let us see how this changes because the portfolio will continue to generate returns over the period. Let us assume the returns are 12% on equity and 7.5% on debt, let us see how long it may take to rebalance with this strategy?

 

With the given assumptions:

 

  • Equity returns: 12% per annum
  • Debt returns: 7.5% per annum
  • Annual new contributions to debt: ₹1,00,000

It would take approximately 5 years to bring the portfolio’s equity allocation down to close to the target 60% equity and 40% debt (achieving ~57.34% equity and ~42.65% debt).

 

Final Portfolio After 5 Years:

  • Total Portfolio Value: ₹23,05,065
    • Equity Value: ₹13,21,756 (57.34%)
    • Debt Value: ₹9,83,309 (42.65%)

 

This strategy has reduced the equity-heavy bias without selling any stocks and incurring capital gains taxes. Over time, as you continue to prioritize new investments into debt instruments, your portfolio will naturally align closer to the desired 60:40 target.

 

 

Other ways to minimise tax impact:

 

 

Key strategies to minimize tax cost while rebalancing:

 

  • Harvesting losses: If you need to sell in your taxable account, consider selling assets that are currently at a loss to offset capital gains from other investments, reducing your overall tax liability, as also locking in the gains.
  • Specific considerations with Capital Gains Tax:  
  • Long-term capital gains tax: In India, long-term capital gains on equity investments held for more than 12 months are taxed at 12.5% (above Rs. 1.25 lakh per year), so consider holding assets for the long term to qualify for this lower tax rate.
  • Short-term capital gains tax: Short-term capital gains (held for less than 12 months) are taxed at 20%, so prioritize selling long-term holdings when rebalancing.
