Portfolio rebalancing is a crucial aspect of investing in mutual funds. It involves periodically reviewing one's investment portfolio and adjusting to align it with the original asset allocation. This can potentially help investors to capture upside returns while keeping risks within defined limits. In the Indian mutual fund industry, where thousands of new investors participate each year, understanding the risk-return dynamics of portfolio rebalancing is essential.

In this article, we discuss the key risks-return trade-offs in portfolio rebalancing for mutual fund investors and strategies to optimise the gains while managing downside risks.

Understanding risks in portfolio rebalancing

Equity markets are inherently volatile in the short term, and disproportionate exposure to equities can potentially pose a risk to portfolio values. Several factors can impact Indian equity markets and the rebalancing process. Let us take a look at the key factors.

Market risk: Sharp corrections in equity markets can lead to losses for funds heavy on equities during rebalancing. For example, the 2020 market crash impacted many investors' portfolios.

Liquidity risk: During periods of high volatility, mutual funds may impose redemption restrictions, exposing investors to liquidity risk. The 2020 crash saw such restrictions by some funds.

Interest rate risk: Changes in interest rates can impact debt funds' net asset values during rebalancing. Rising rates may potentially lead to capital losses for existing fixed-income instruments in a portfolio.

Company/sector-specific risk: Overexposure to particular stocks or sectors carries risk of losses from company or sector-specific events.

Thus, risks from market conditions, mutual funds' liquidity profiles, interest rate movements and company performances need to be accounted for while rebalancing. Diversification across asset classes, companies and sectors can help mitigate such risks.

Optimising return potential in portfolio rebalancing

While risks persist, a rebalanced portfolio also provides opportunities to enhance the return potential over the long term. Below are some pointers.

Capturing upsides: Rebalancing enforces systematic selling of past outperformers and buying of underperformers, thereby capturing some of the potential upsides.

Reducing volatility: A disciplined rebalanced portfolio maintains the intended asset allocation mix, improving the risk-adjusted return potential over time through lowered volatility.

Triggering capital gains: Over time, profit booking during periodic rebalancing results in long-term and short-term capital gains, optimising the post-tax returns for investors in applicable tax brackets.

Asset allocation gains: Sticking to the strategic asset allocation as markets fluctuate can potentially help investors to capture benefits from the varied cycles of different asset classes, thus enhancing the risk-adjusted return potential.

Reinvestment rates: Systematic investments/SIPs during market corrections can benefit from the rupee cost averaging effect, improving the portfolio return potential in the long run.

The risk-return trade-off in portfolio rebalancing

The central challenge in portfolio rebalancing is navigating the risk-return trade-off. Aggressive rebalancing to increase upside potential may raise volatility risks. Conversely, conservative rebalancing focused only on risk control may forego potentially available return opportunities. Striking a nuanced balance is important.

Some key considerations around the trade-off include

  • Understanding your individual's risk profile and time horizon
  • Maintaining systematic discipline in rebalancing
  • Using tactical opportunities judiciously
  • Executing rebalancing gradually instead of making abrupt changes.

For example, a young investor can afford to take on relatively higher risk and to optimise the long-term return potential. In contrast, a retired investor relies more on risk control for steady cash flows and capital preservation. Gradual execution and diversification can help mitigate trade-offs in both scenarios.

Strategies for minimising risks & optimising return potential in portfolio rebalancing

Based on the above factors, here are some viable strategies mutual fund investors may adopt for successfully navigating the risk-return trade-offs of portfolio rebalancing.

  • Define clearly your return expectations and risk appetite
  • Maintain asset allocation discipline through periodic, systemic rebalancing
  • Diversify widely across asset classes, sectors, market caps and companies
  • Invest in high-quality equity and debt funds with long-term track records
  • Consider flexi-cap funds for their tactical asset allocation abilities
  • Rebalance gradually in volatile phases instead of attempting market timing
  • Book profits selectively from past outperformers for locking gains
  • Redeploy profits in undervalued segments/schemes for upside potential
  • Leverage SIPs for participation in downward price movements
  • Synchronise rebalancing with financial goals to maintain required returns
  • Take expert advice if needed on navigating dynamic market conditions


A disciplined, diversified and goal-based approach to portfolio rebalancing is imperative for mutual fund investors seeking optimal risk-adjusted returns over long periods of market volatility and uncertainty. Understanding risks, returns and mutual fund trade off in portfolio rebalancing can assist investors in making prudent investment decisions. By doing this effectively, investors can leverage the full potential of regular rebalancing practices for potentially meeting their life goals.


What is the ideal frequency for rebalancing a portfolio?
A. The ideal frequency for rebalancing a portfolio is said to be every 3-6 months. Regular rebalancing ensures the asset allocation of the portfolio stays aligned with the investor's risk tolerance and investment objectives.

How can I determine my risk tolerance level?
A. You can start by considering your investment time horizon and to what extent short-term fluctuations in your portfolio would affect you emotionally. Answering questionnaires designed to assess your reaction to different investment outcomes can also provide insight into your risk tolerance. Speaking to a financial advisor and reflecting on your personal financial situation and goals can further help you identify the level of risk you are comfortable taking with your investments.
